Concept

all a cart system

An “a la cart” (spelled as “all a cart” in the transcript) ordering system means you can buy individual suspension components instead of being forced to purchase a complete kit. For off-road builders, this can make it easier to upgrade only the parts you need (like specific brackets) and match components to your existing setup.

Term

integrated bump stop

A bump stop is like a safety cushion for your suspension. When the suspension compresses a lot on rough trails, it hits the bump stop to prevent damage and keep things from slamming into the end of travel.

Term

Johnny joints

Johnny joints are special connection joints used in off-road suspension. They let the suspension move through rough terrain without binding, and they can be rebuilt so you don’t have to replace everything when they wear out.

Term

hymes

Hymes are basically heavy-duty ball-and-socket style joints used in suspension. They help the suspension links move freely as the wheels travel up and down over rough ground.

Term

aluminum links

Aluminum links are the suspension arms that connect parts of the lift kit. Using aluminum can make them lighter, and in this case the host says the kits include them without extra cost.

Topic

Trail Revival program

Trail Revival sounds like a community program that helps support and maintain off-road trails. The host says they got to participate and do maintenance on a famous trail.

Wrangler Rubicon
Car

Wrangler Rubicon

The Jeep Wrangler is an off-road SUV made for driving on rough trails. The podcast mentions using it for maintenance related to the Rubicon Trail, which fits how people use Wranglers on challenging routes. It’s a popular choice because it’s built specifically for 4x4 driving.

Ford Ranger
Car

Ford Ranger

The Ford Ranger is a pickup truck, meaning it has a cargo bed for hauling things. People talk about it in off-road podcasts because it can be set up to drive on rough trails and still be useful for everyday tasks. It’s also popular because there are lots of parts and upgrades available.

Aston Martin Vanquish
Car

Aston Martin Vanquish

The Aston Martin Vanquish is a luxury sports car designed for speed and comfortable highway driving. It’s not an off-road vehicle by design. In the podcast, it’s mentioned as a specific car name they could use or talk about.

Term

V eight

“V8” means the engine has eight cylinders arranged in a V shape. They’re saying it’s not about being super fast—it’s about how smooth and nice it feels to drive.

Term

NVH

NVH is how noisy and bumpy a car feels—things like road noise and vibration. They’re saying the Lexus is much quieter and smoother than their Jeep.

Jeep Grand Cherokee
Car

Jeep Grand Cherokee

They’re talking about a Jeep Grand Cherokee from the early 1990s. It’s an SUV that people use for trails, and they’re pointing out that even back then it had lots of basic electronic warnings and features.

Term

electronic everything

They mean the truck/SUV has lots of features controlled or monitored by electronics. Instead of simple switches and gauges, it can show warnings on a screen for things like lights or doors.

Jeep JK
Car

Jeep JK

“JK” is a Jeep Wrangler generation. In this conversation, they’re comparing how the JK feels compared to an older Jeep, especially in terms of features and electronics.

Term

almost no electronics

They’re talking about having a simpler off-road vehicle with very few electronic features. The point is that it can be easier to deal with when you’re out on trails because there’s less complicated stuff that can break.

Term

poverty edition

They’re using a joking term for a “basic” version of the vehicle with fewer features. Here it means the windows/controls aren’t as convenient as on a more fully equipped trim.

Lexus GX470
Car

Lexus GX470

The Lexus GX470 is a Toyota-based luxury SUV with a V8 engine and a sturdy off-road-style frame. It’s related to the Land Cruiser/4Runner family, but it’s the more “luxury” GX version.

Lexus GX460
Car

Lexus GX460

The Lexus GX460 is the newer version of the GX compared with the GX470. The number in the name is meant to hint at the engine size (displacement).

Term

displacement

Displacement is basically how big the engine is inside—how much space the cylinders move through. The bigger the displacement, the more air/fuel the engine can potentially move, which is why car model names sometimes reference it.

Land Cruiser
Car

Land Cruiser

The Toyota Land Cruiser is a tough, off-road SUV that’s known for being built to last. People often spend a lot of money turning them into serious trail rigs, so it has a different “build budget” and culture than cheaper Toyota projects.

Concept

modular

“Modular” just means the system is built from parts that can be rearranged or reused. They’re saying their portal setup is designed so you can move it to a different truck/SUV without starting from scratch.

Term

adapter plates

Adapter plates are mounting interfaces that let the same hardware fit multiple vehicle platforms. Here, they’re used so portal components can be removed from one SUV and installed on another without replacing the whole system.

Term

one ton axles

“One ton axles” means beefier, heavier-duty axle parts meant to handle more stress. The point here is that upgrading axles on one vehicle doesn’t guarantee the same parts will work on another.

Term

IFS rig

IFS means the front wheels move independently from each other. That can affect whether certain off-road parts (like axle setups) will work the same way as they do on a solid front axle.

GX 470
Car

GX 470

The Toyota GX 470 is an SUV built to handle rough roads. In this story, they added portal-style gearing to make it easier to clear obstacles by lifting the wheels higher.

Place

Hollister

They took the GX to a nearby place called Hollister to try it out off-road. It’s basically where they tested the setup in real conditions.

Concept

break in period

A break-in period is the early stage after something new is installed or rebuilt, when parts need time to “seat” properly. They’re basically saying they might not have followed that fully before going off-road.

Concept

portals

“Portals” are an off-road upgrade that raises the vehicle’s axle area using gearing near the wheels. The goal is more ground clearance so the truck can go over obstacles without scraping.

Part

TRD 2024 runner shocks

They’re talking about replacing the shocks—one at each wheel—with TRD shocks. Shocks help keep the tires planted on rough terrain, and the “better” shock design is meant to handle repeated bumps without fading.

Term

piggybacks

Piggyback shocks have an external reservoir mounted on top of (or alongside) the main shock body. That extra reservoir helps manage hydraulic fluid and heat, which can improve damping consistency during repeated hard off-road use.

Term

IVP two point five

“IVP 2.5” is a model/spec detail for the shock. It’s basically part of how the shock is built and tuned so it can better handle rough driving and keep the ride controlled.

Term

Gen three bump stops

Bump stops are like safety cushions for your suspension. They keep the suspension from getting crushed when you hit big bumps, and “Gen three” means a newer version of that design.

Place

King of the Hammers

King of the Hammers is a famous off-road race where people drive over very rough rocks and obstacles. If they’re talking about it, they mean the vehicle is being tested in extreme conditions.

Place

Johnson Valley

Johnson Valley is a well-known off-road area in California. It’s where big events like King of the Hammers happen, and the terrain is tough on vehicles.

Place

Turkey Claw

Turkey Claw is a specific rough obstacle they went to test on. It’s the kind of spot where you might get stuck and need a winch.

Term

rock crawling

Rock crawling is when you drive slowly over rocks and rough trails. The goal is to keep the tires gripping while the suspension moves a lot. It’s a good way to test whether a 4x4 setup can handle tough terrain without breaking.

Term

whoops

“Whoops” are rough, bumpy sections of trail made of repeated dips and rises. They make the suspension bounce quickly and can shake the truck hard. Hitting them is a good stress test for parts that might loosen or break.

Term

airbags popped out

“Airbags popped out” here likely means the truck’s air-suspension components extended a lot when the suspension flexed. That usually happens when the vehicle is pushed to its limits on rough terrain. It’s a clue that the suspension travel is being used up.

Term

rear springs

Rear springs are the parts that help your truck or SUV ride over bumps without getting slammed. If you don’t have them, the suspension has to rely on the backup cushions instead.

Concept

stress testing

Stress testing means pushing a vehicle or component through demanding conditions to reveal weaknesses before they become failures. In this context, the long drive and portal suspension load helped uncover a small issue early so it can be resolved proactively.

Place

Poison Spider

Poison Spider is the name of a specific off-road trail section. People who wheel there recognize it as a distinct part of a bigger route.

Concept

trifecta

In off-road event talk, “trifecta” means completing three named trail sections or obstacles as a set. Here it’s tied to a specific route sequence—Poison Spider, Golden Spike, and Gold Bar Rim—so it’s a structured challenge rather than a generic “three trails” idea.

Place

Golden Spike

Golden Spike is another named trail section the group tackled as part of their three-part route. In off-road communities, these named sections are used like “stages,” so the name signals a particular obstacle and typical driving approach.

Place

Gold Bar Rim

Gold Bar Rim is another named trail section they drove as part of their three-part challenge. It’s the kind of place off-road groups talk about by name because it has its own difficulty.

Term

rear lunchbox locker

A “lunchbox locker” is a traction upgrade inside the rear axle. It helps both rear wheels work together when you’re stuck or climbing over slippery rocks, so you don’t lose traction as easily.

Term

coilovers

Coilovers are suspension parts that help the wheels move smoothly over bumps. Off-road builds use them to keep the truck stable and maintain traction on rough trails.

Term

long arm

“Long arm” refers to a suspension upgrade where the control arms are lengthened compared to stock. This typically increases suspension articulation and improves ride quality on trails, because the suspension geometry stays more favorable as the wheels move up and down.

Term

40s, 42s

“40s, 42s” means they’re running very large tires—around 40 to 42 inches. Larger tires help you clear rocks and ruts, but they can make the truck heavier and harder to drive without the right setup.

Term

V notch

A “V notch” is a tricky spot on a trail that looks like a V-shaped dip or cut. It can make one wheel lose contact or traction, so you have to pick the right line and keep control of your throttle.

Term

front right tire lifted off the ground

When one tire lifts off the ground, it stops gripping the trail. If the other tires don’t have enough traction, the vehicle can start sliding instead of climbing.

Term

winch

A winch is a motorized cable that can pull your vehicle out when it gets stuck. Off-road, it’s a backup plan when the tires can’t get enough grip to keep moving.

Term

optional line

An “optional line” is a different way to go through the obstacle. It’s usually chosen when you want an easier or safer route than the main, harder path.

Term

wedgie

“Wedgie” sounds like the name of a specific obstacle on that trail. It’s likely a wedge-shaped section that makes it harder to keep traction and stay pointed the right way.

Term

hard right turn

A “hard right turn” means you turn the steering sharply. On rough trails, that can shift the vehicle’s weight and grip, which may make it lurch or lose its smooth climb.

Term

double step up

A “double step up” is a trail feature with two raised sections close together. It’s hard because the truck has to climb both parts without losing traction or getting hung up.

Term

40 inch tires

“40 inch tires” are huge off-road tires that sit higher and roll over rocks and ruts more easily. They also usually require other upgrades so they can fit and still steer and ride properly.

Term

spacer leveling kit

A leveling kit is a simple lift that raises the truck to make it sit more level. It can help fit bigger tires, but it’s not the same as a full suspension lift designed for serious off-road travel.

Term

ring gear

The ring gear is a big gear inside the axle that helps send power to the wheels. When you drive hard off-road, the axle takes big hits, and a stronger ring gear helps it survive.

gladiator
Car

gladiator

The Jeep Gladiator is a pickup truck that’s meant for off-road use. The discussion is about how strong its axle internals are, which matters when you hit obstacles hard on a trail.

Term

M220

M220 is an axle/differential model designation used by Jeep for certain Gladiator configurations. It’s being referenced here because different axle models use different internal gear sizes and designs, which affects how much abuse they can take on trails.

Term

Dana, forty fours

Dana makes a lot of the axles used in trucks and SUVs. “44” is a common way people refer to a particular axle family, and it’s used as a quick strength comparison for off-roading.

Term

throttle

Throttle is how much you’re asking the engine for power. On rough trails, the timing of when you press or lift off the throttle can affect traction and whether parts get hit with damaging shock loads.

Concept

backup

“Backup” here means reversing to see if the vehicle is still mechanically okay. If it can move in reverse, it suggests the drivetrain didn’t fully break.

Toyota FJ Cruiser
Car

Toyota FJ Cruiser

The Toyota FJ Cruiser is an off-road SUV made for driving on rough trails. The episode mentions a red one they saw during a long day out, which shows how common and memorable these vehicles are on trails. It’s a popular choice for people who want something rugged and easy to recognize.

Term

aired up

“Aired up” means you pumped your tires back to a higher pressure. Off-roaders often lower tire pressure for better grip on dirt, then raise it again when they’re heading back to normal roads.

Part

rear diff

The rear diff is the gearbox for the back axle. It helps the two back wheels turn at slightly different speeds, which matters when you’re turning or driving on uneven ground. If it breaks, you may need to swap in another one that has the right gear setup.

Term

same gearing

“Gearing” means the gear ratio inside the differential. If you replace a diff, it needs to have the same ratio as the original so the wheels and drivetrain stay in sync and the truck drives the way it should.

Term

dropout thirds

“Dropout thirds” is a design that lets you remove the differential’s center section more easily. That means you can swap or repair the diff faster instead of doing a much bigger teardown.

Topic

EJS industry

EJS is a big off-road event in Moab where lots of Jeep and off-road people gather. It’s a time when you’ll see a lot of builds, parts, and repairs happening.

Topic

Moab

Moab is a famous off-roading area where people drive challenging trails. Because the terrain is tough, it’s common to do repairs while you’re there.

Term

third member

A “third member” is basically the center gearbox section inside the differential. Off-roaders swap it out because it’s faster than tearing everything apart when gears or bearings get damaged.

Term

used gears

“Gears” are the differential’s internal gear teeth that set the ratio. Changing them affects how the truck pulls at low speeds versus how it feels at higher speeds.

Topic

Cliffhanger

“Cliffhanger” is the name of a trail/obstacle the group drove. The host is implying it’s tough enough that they needed to swap parts (like the differential) to be ready. Trail names like this usually mean there’s a known difficult section ahead.

Concept

pre run

A “pre run” is when you drive a trail ahead of an event to learn the route, identify difficult sections, and plan your vehicle setup and recovery strategy. The host connects it to their differential choice and their decision-making at the breaking point—taking it easy and using recovery options rather than repeating mistakes. In off-roading, pre-running can reduce surprises and help you match traction hardware to the terrain.

Lexus GX
Car

Lexus GX

The Lexus GX is a rugged 4x4 SUV. In this discussion, they’re talking about the rear axle/differential setup, which affects how the truck handles and how strong it is. They mention different rear gear sizes used across model years.

Toyota 4Runner
Car

Toyota 4Runner

The Toyota 4Runner is a popular off-road SUV. Here they’re talking about the rear axle/differential gears, which can change strength and gearing. They say it used one gear size for earlier years, then changed in 2010.

Term

8.2

“8.2” is a shorthand for the size of the rear differential’s main gear. That gear size can matter for how the axle is built and how it performs under load. The hosts are using it to compare different rear-axle versions across years.

Term

factory locker

A factory locker is a rear-axle feature that forces both wheels to turn together. It helps when one tire starts slipping, like on rocks or mud.

Term

8.2s

“8.2s” here means a specific size of rear differential setup. The point is that some people think it may not hold up well if you push it hard off-road.

Term

ring and pinion

Ring and pinion are the main gears in the rear differential. They determine the “gear ratio,” which changes how the vehicle pulls and how it feels at speed.

Term

carrier

The carrier is the internal housing that holds the differential gears in place. A stronger carrier can help the differential survive harder off-road driving.

Term

4.9 inch

“4.9 inch” sounds like a shorthand for a specific rear differential/gear setup. They’re comparing different axle/diff options to find one that works best for their build.

Term

nine inches

“Nine inches” refers to the popular Ford 9-inch-style differential ecosystem (ring gear size and associated axle/diff parts). Enthusiasts like it because there’s a wide aftermarket and many gear/locker options, making it easier to build a strong, trail-capable setup.

Term

10 and a half inch tundra axle

They’re talking about using a larger Toyota Tundra rear axle/differential setup. The idea is that the bigger hardware can be stronger and may fit better for their off-road goals.

Term

clearance

Clearance is how much space you have between the ground and the lowest parts of the truck. More clearance means you’re less likely to scrape the rear axle on rocks or ruts.

Term

factory E locker

A “locker” is a feature that forces both wheels on an axle to turn together. The “E” part means it’s controlled electronically, helping you get traction when one wheel starts slipping.

Term

373 gears

“Gears” here means the differential ring-and-pinion ratio, commonly written as a number like 3.73. A lower numerical ratio (like 3.73) generally helps balance highway drivability with off-road torque needs, depending on tire size and vehicle gearing.

Term

unsprung weight

Unsprung weight is everything that moves with the wheels instead of being supported by the suspension. If it’s heavier, the suspension has a harder time keeping the tires planted over rough ground.

Term

unit bearing pattern

The “unit bearing pattern” is the way the wheel bearing mounts to the axle. If the pattern doesn’t match, the upgrade won’t fit or line up correctly.

Term

stub shaft

A stub shaft is a short part of the axle near the wheel. For an axle upgrade to work, it has to match the portal’s input so the gears and splines line up.

Term

input gear

The input gear is the gear that takes power coming into the portal/axle unit. It has to match the rest of the drivetrain parts so everything locks together and drives correctly.

Term

30 spline

Splines are the ridged connection that lets two parts slide together and transfer power. “30 spline” means the ridges count must match for the parts to fit and drive correctly.

Tacoma
Car

Tacoma

They’re talking about the Toyota Tacoma pickup truck. They mention older and newer generations because off-road parts often work across those model years.

GX470 and GX460
Car

GX470 and GX460

They’re mentioning two Toyota GX models from different years. Even though they’re similar SUVs, the exact generation can change how parts and electronics fit.

second gen Sequoia
Car

second gen Sequoia

They’re also including the Toyota Sequoia from the second generation. The idea is that even though it’s a different model, it can still use the same general setup.

LX570
Car

LX570

They mention the Lexus LX570, which is closely related to the Toyota Land Cruiser. They’re saying their parts/setup can apply to both, not just the Toyota.

second gen Tundra
Car

second gen Tundra

They’re talking about the Toyota Tundra from the second generation. They’re grouping it with other Toyota/Lexus models because parts and electronics can be similar within that timeframe.

Term

knuckle

A knuckle is a metal part in the front suspension that helps the wheel steer. If the knuckle shape is the same, it’s easier to make parts fit and work correctly.

Term

ABS

ABS is the system that helps your brakes keep the wheels from locking up. They’re saying it can be tricky to work around because it’s tied into the car’s electronics and computers.

Term

computers get more and more complicated

Modern cars have more computer-controlled systems than older ones. If you change something the computer relies on, it can cause warning lights or make the car behave differently.

Term

long travel kits

Long travel kits are suspension upgrade packages designed to increase wheel travel—how far the suspension can move up and down. More travel helps the tires stay in contact over uneven terrain, which matters for rock crawling and big-tire setups. The guest contrasts long travel options with what’s best for “going fast” versus crawling-focused clearance and design.

Brand

Marlin Crawler

Marlin Crawler is a company that makes off-road suspension parts, especially for rock crawling. Here, they’re using Marlin Crawler’s kit as a “baseline” that people compare other Toyota suspension builds to. It’s considered a strong starting point for clearance and big tires.

Term

one ton swap

A “one ton swap” is when you upgrade to heavier-duty axles from a bigger truck class. It’s meant to make the drivetrain handle tougher off-road use and bigger tires. They’re comparing this option to just upgrading the current axles.

Brand

Accutune

Accutune is a company that makes suspension lift kits for off-road trucks. In this episode, they’re using it as an example of a lift kit choice for a Toyota build that’s serious but not the most extreme. The goal is to fit 33s or 35s without going portal.

Term

Fox 2.2 point 0s, 2.5s

Fox makes off-road shocks. The “2.2” and “2.5” are different shock sizes, and bigger ones are often chosen for heavier or more extreme off-road setups. Here they’re talking about which shock sizes go with their lift kit plan.

Term

regearing

Regearing is when a shop changes the gear ratios in the axle. It helps the truck feel right again after changes like bigger tires or a lift, especially for slow off-road driving.

Term

RCB axle shafts

Axle shafts are the parts that transfer power from the drivetrain to the wheels. RCB axle shafts are upgraded replacements meant to handle tougher off-road use and reduce the chance of breaking.

Term

chromoly axle shafts

Chromoly axle shafts are stronger upgraded axle parts made from a tough steel alloy. They’re used to better survive hard off-road driving where the drivetrain takes a lot of stress.

Term

axle truss

An axle truss is a brace that stiffens the axle. It helps the axle resist bending when you hit rocks or load up the suspension hard off-road.

Term

lift kit

A lift kit raises the truck so it sits higher. That usually helps with tire clearance and ground clearance, but it can also require other upgrades to keep everything working correctly.

Term

IFS clamshell ones

This is a type of lift-kit setup for trucks with independent front suspension. It uses special bracket pieces (“clamshell” style) and usually takes more work to install correctly.

Term

axle trust

This sounds like they mean an axle brace (an axle truss). It’s added to keep the axle from bending as much when you drive off-road.

Term

35

“35” is a shorthand for tire size—usually 35-inch tires. Bigger tires can rub or require extra changes, so the hosts talk about needing additional work. Portals can help make the fitment easier.

Term

transferability

In this context, “transferability” means how easily the expensive off-road upgrade (like portal hardware) can be moved from one vehicle to another later. The hosts frame portals as an investment because you can transfer them between vehicles, unlike some one-off modifications. This is a cost-of-ownership consideration rather than a technical performance term.

Term

mid travel

“Mid travel” means the suspension can move farther than stock, but not as far as a full “long travel” off-road setup. Here, the hosts are saying portals can give you some extra movement, especially when crawling slowly. It’s more about controlled flex than extreme suspension travel.

Term

37s, 38s

“37s, 38s” means even bigger tires—around 37-inch and 38-inch. The hosts are saying portals give you enough clearance that you can move up to those sizes without doing as much extra modification. Bigger tires help with traction and obstacle clearance.

Part

control arms

Control arms are parts that hold the wheel in place and let it move over bumps. They also affect alignment, like how the tire sits in relation to the road.

Term

camber

Camber is the tilt of the tire—whether the top of the tire leans in or out. Getting it right helps the tire wear evenly and grip better.

Term

scrubber radius

Scrub radius is a steering-geometry measurement that affects how the truck feels when you turn. It can change steering effort and how the steering reacts when the tires hit uneven ground.

Term

offset

Wheel offset is how far the wheel sits inward or outward compared to the hub. Moving it changes tire clearance and can also change steering feel.

Term

mechanical trail

Mechanical trail is a geometry measurement that affects how “self-centering” your steering feels. More mechanical trail usually makes the car want to go straight and feel more stable, especially at speed.

Term

caster angle

Caster angle is the tilt of the steering “pivot” in the front suspension. If it’s small, the steering can feel twitchier and you may have to keep correcting to stay straight; more caster helps the car track better.

Term

wheel spacer

A wheel spacer is a part that moves your wheel slightly outward from the truck. That can help stop rubbing when you run bigger tires, but it needs to be set up correctly so everything still fits and handles safely.

Term

body mount chuck

“Body mount chop” (often shortened to “chuck” in casual speech) is trimming or modifying the truck’s body mount area to create more tire clearance. It’s commonly needed when increasing tire size beyond what suspension geometry alone can accommodate.

Term

scrub radius

Scrub radius is a steering geometry measurement that affects how the tire “tracks” as you turn. In this segment, they’re saying the portals change scrub radius, which can help or hurt tire clearance depending on the setup.

Term

lower control arm

The lower control arm is a suspension link that helps hold the wheel in the right spot. If you adjust it, you can move the wheel slightly so the tire rubs less when you turn all the way.

Concept

portal pros

Portal-style axles use extra gearing near the wheels to lift the truck higher. It can make it easier to crawl over obstacles, but it also changes how the drivetrain and axle parts have to be set up.

Term

RCLT kit

RCLT here refers to a particular long-travel suspension kit option. They’re comparing how much the kit costs now versus before, and then adding the other parts you still need to finish the build.

Term

RAVflow shocks

RAVflow shocks are the upgraded shock absorbers they’re budgeting for. With long-travel suspension, you need shocks that can handle the extra movement so the truck stays controlled on rough trails.

Term

Aki tunes rear suspension kit

Aki tunes rear suspension kit is a rear suspension parts package they’re comparing for cost. Rear suspension upgrades are often needed to make long-travel builds work properly, especially when you’re running big tires.

Term

RCVs

RCVs are upgraded axle-joint parts that help the drivetrain survive rough off-road use. They’re part of the front-axle upgrade cost when building for extreme suspension and big tires.

Term

rear axle

The rear axle is the main drivetrain part that connects the rear wheels to the rest of the truck. When you lift the truck and change suspension, you often need to update the rear axle setup so everything still fits and works correctly.

Term

Dana 60

Dana 60 is the name of a rugged axle used on many off-road trucks. They’re saying you can upgrade gears/parts for a Dana 60 in a relatively straightforward way, which helps when you’re running huge tires.

Term

drive shaft install

A drive shaft (prop shaft) transfers power from the transmission to the differential(s). When you lift a truck or change axle components, the drive shaft often needs replacement or rework to maintain correct length and angles for smooth, reliable operation.

Term

full float

A full-float axle is a design where the wheel is supported by bearings in the axle housing, not by the axle shaft. That can make the axle shaft less stressed and is common in serious off-road setups.

Term

35 spline

Splines are the ridges/teeth that lock a shaft to a matching part. The host is saying the portal conversion uses a 35-spline connection for the portal side.

Term

stock diff

The differential (diff) is the gear in the axle that lets the wheels turn at different speeds when you’re cornering. They’re saying the portal parts have to match the stock differential so everything connects correctly.

Term

ARB

ARB is a well-known off-road brand that makes upgrades for the differential, like locking it for traction. The host is saying you can upgrade to an ARB setup that matches the 35-spline driveline parts.

Term

transfer cases

A transfer case is the box in a 4x4 that sends power to both the front and rear wheels. The comment is basically saying “don’t put the change in the wrong spot in the drivetrain,” because that area is critical to how power gets distributed.

Term

gussets

Gussets are reinforcement pieces—usually metal plates—that make a bracket or frame area stronger. They help the parts resist bending when you hit rocks or ruts.

Term

gear reduction

Gear reduction means the drivetrain turns the wheels more slowly but with more pulling power. Portal setups use this to help the vehicle crawl and climb better at low speeds.

Term

floor jack

A floor jack is the tool you use to lift the vehicle off the ground so you can work underneath it. They’re saying the install can be done at home, but you may need basic lifting tools first.

Term

jack stands

Jack stands are the safety supports that hold the car in place while you’re working under it. Using them is important because a jack alone isn’t meant to be the only support.

Term

airbag suspension

“Airbag suspension” is suspension that uses air-filled bags to support the vehicle. They’re joking that trail damage can hit the air suspension first, before you ever get to the portal parts.

Place

Rubicon trail

The Rubicon Trail is a well-known tough off-road trail in California. They’re saying they want to do an install test there, where the terrain is rough enough that you might need to fix things on the trail.

Super Duty
Car

Super Duty

“Super Duty” is Ford’s heavy-duty truck line. The hosts are talking about whether their off-road portal axle kit should be offered for that truck, and what tire sizes they can safely cover under warranty.

Part

14 bolt

“14 bolt” is a type of axle used on some GM trucks, named for the differential cover’s bolt count. Off-road builders choose it because it’s strong and easy to find parts for.

Term

43 inch stickies

“Stickies” means tires designed to grip really well on rocks and dirt. Bigger “stickies” (like 43-inch) can stress the truck’s drivetrain more, which is part of why they’re worried about warranty coverage.

Term

taller lift

A “taller lift” raises the truck higher off the ground. It helps with tire clearance and obstacles, but it can also make other parts work harder, especially when you go bigger on tires.

Term

deeper ratio

“Deeper ratio” means the gearing is changed so the truck has more pulling power at low speeds. That helps when crawling over obstacles instead of trying to go fast.

Term

junk art axles

“Junk art axles” sounds like a nickname for cheaper axle setups. They’re saying some people buy the cheaper stuff to save money, but then might still end up spending a lot later.

Term

ungear

“Ungear” here means changing how the drivetrain is geared so the truck can roll and not feel like it’s fighting the gearing. They’re debating whether they’d have to adjust gearing for the new tire size and setup.

Term

Dana 40

Dana 40 is the name of an axle assembly from a company called Dana. Axles are the parts that transfer power to the wheels, and the hosts are saying these portal/axle setups have to survive bigger tires and hard driving.

Term

burnouts

A burnout is when you spin the tires on purpose to make them slip and heat up. The hosts are pointing out that this kind of hard driving is tough on drivetrain parts.

Term

42 inch tires

That means the tire is roughly 42 inches tall from top to bottom. Larger tires can help you get over rocks and ruts more easily, but they’re heavier and may require other upgrades so everything fits and works right.

Term

R and D

“R and D” is short for research and development. It means they test and improve a product step-by-step, often by trying it in real conditions to see what breaks and what needs changing.

Term

power steering pump

The power steering pump helps your steering by supplying the system with pressurized fluid. If it goes bad, the steering can suddenly feel very hard, which is dangerous when you’re trying to maneuver on a trail.

Term

power steering fluid

Power steering fluid is the liquid that helps your steering feel lighter. If it leaks out, the steering can get hard and the pump that moves the fluid can overheat. That’s why they’re worried about not running it completely dry.

Term

B lock

“B lock” is shorthand for a locking differential (often discussed as “locker” in off-road circles). A locking differential forces the left and right wheels on an axle to rotate together, improving traction when one wheel would otherwise spin. The speaker is saying they don’t have that traction aid, which affects how the Jeep behaves on difficult terrain.

Term

Fox 2.5 shocks

Fox 2.5 shocks are heavy-duty shock absorbers made by Fox. The “2.5” refers to the shock’s size, and bigger shocks usually help the truck ride better over bumps and rough trails.

Concept

lower my suspension

“Lowering the suspension” means making the truck sit closer to the ground. Off-road builders sometimes do this for handling or looks, especially if another mod (like portals) still keeps enough clearance for trails.
