E-lockers

An E-locker is a device that helps a truck or SUV get traction when one wheel starts slipping. It locks the two wheels together on the same axle so both can push instead of one just spinning.

Brand

ARB

ARB is a company that makes off-road traction parts. Here, they’re being compared to other locking-differential systems to see how they differ for off-roading.

Term

locking differential

A locking differential is a traction device that stops one wheel from spinning faster than the other on the same axle. It helps the vehicle keep moving when one side loses traction.

Term

IFS

IFS means the front suspension is designed so each front wheel can move more independently. That can make some off-road builds harder because the suspension parts are more complex and take more work to strengthen for rough trails.

Term

rock-crawler build

A “rock-crawler build” is a truck or SUV set up to crawl over rocks slowly. It usually includes extra clearance and protection so the vehicle can survive bumps and scrapes.

Term

37s or 40s

“37s or 40s” means very large off-road tires, around 37 inches or 40 inches tall. Bigger tires can help the truck climb over obstacles, but they’re heavier and more expensive.

4Runner Forerunners
Car

4Runner Forerunners

The Toyota 4Runner is an SUV made for rough roads and off-road trails. It’s built to handle long trips and tough conditions, and people often modify them for camping and driving on dirt. The podcast mentions different generations because the 4Runner has changed over time.

Term

front-wench bumper

A winch bumper is a stronger front bumper built to hold a winch. The winch helps you pull yourself (or others) out if you get stuck off-road.

Term

skid plates

Skid plates are protective covers on the bottom of the truck. They help prevent damage when you hit rocks or drive over rough ground.

Term

33 to 35 inch tires

“33 to 35 inch tires” are big off-road tires. The bigger size helps the truck clear obstacles, and it’s part of the common build formula the host is criticizing.

Term

bolt-on market

The “bolt-on market” means aftermarket parts you can install without major custom fabrication. The host is saying that makes lots of builds look similar unless you choose different components.

Term

two to three inch lift

A lift raises your truck higher off the ground. That extra clearance can help you drive over obstacles without scraping the underside.

Term

33s

“33s” means the truck is running about 33-inch-tall tires. Larger tires can grip better and clear bumps, but they can change how the truck drives.

Term

rock sliders

Rock sliders are metal rails under the sides of a truck. They’re there to protect the body when you scrape or hit rocks on the trail.

Term

winch

A winch is a motorized cable that can pull a vehicle out of trouble. Off-roaders use it for recovery when they get stuck.

Term

Bilstein 5100 lift

Bilstein 5100 is a well-known suspension upgrade brand/model used to raise a truck a little. It usually means better shocks/struts set up for a higher ride height so the truck still drives reasonably well.

Term

long travel

Long travel means the suspension is set up to move farther up and down than normal. That helps the tires stay on the ground when you hit rough terrain.

Term

swing out

A “swing out” is a rear-mounted piece that opens like a door on hinges. Off-road rigs use it so you can reach the back of the truck more easily, often for a spare tire or gear.

fifth gen forerunners
Car

fifth gen forerunners

That phrase is talking about a specific generation of the Toyota 4Runner. Builders mention the generation because the truck’s body and mounting points change, so the same off-road parts don’t always fit the same way.

third gen Tacomas
Car

third gen Tacomas

That phrase means a specific generation of the Toyota Tacoma pickup. Off-road builders talk about generations because the truck’s shape and mounting points change over time, which affects what mods will fit.

Wrangler Rubicon
Car

Wrangler Rubicon

The Jeep Wrangler is an off-road SUV made for driving on trails. People often talk about it when they go on famous off-road routes like the Rubicon. In the podcast, they’re mentioning the kinds of comments that come up during those trips.

Place

Rubicon Trail

The Rubicon Trail is a well-known off-road trail in California. It’s famous for being challenging, and when you go there, people pay attention to how different trucks are built.

Part

shock towers

Shock towers are the strong mounting points where the suspension shocks bolt to the vehicle. Off-road builders sometimes redesign them so the shocks can move more without hitting other parts.

Term

12s

“12s” here likely means 12-inch shocks (bigger shocks). Bigger shocks can give more suspension movement, but they can also be harder to fit without hitting other parts.

Term

up travel

Up travel is how far the suspension can move upward when the wheel hits a bump. More up travel can help the tire stay on the ground, but it has to fit without rubbing or blocking other parts.

Term

full widths

In off-road slang, “full widths” usually means wider tire coverage—like fenders or flares that cover the tires more completely. It helps keep the truck cleaner and protects the body when you run bigger tires.

Term

forties

“Forties” usually means 40-inch tires. Bigger tires help off-road traction, but they often require lift and trimming so they fit without rubbing.

Term

frame rails

“Frame rails” are the main strong beams running along the truck’s length. If you mount a winch to the frame rails, the truck can handle the pulling force much better than if it were mounted only to the bumper.

Term

chrome bumper

A “chrome bumper” is the shiny bumper finish you often see on older or classic-looking builds. They’re saying the build kept the chrome bumper looking intact even with the winch installed.

Term

interstate

An interstate is a big highway where cars enter and exit using ramps. It’s usually faster and busier than regular roads, so merging takes more care.

Term

blinker

A blinker is your turn signal. It tells other drivers which way you plan to go so they can react safely.

Term

blind spot

A blind spot is a part of the road you can’t see from the driver’s seat. That’s why cars can “show up” when you change lanes, and why it’s important to check mirrors and be patient.

Term

slow lane

The “slow lane” is the lane where cars usually go slower on a multi-lane highway. The host is saying the other truck was in that lane, which made it harder to notice in time.

Toyota Tundra
Car

Toyota Tundra

A Toyota Tundra is a big pickup truck. The host is talking about a second-generation Tundra with a V8 engine, and using it as an example of a car that can appear in your blind spot during lane changes.

Term

V8 5.7

“V8 5.7” means the truck has an 8-cylinder engine that’s about 5.7 liters in total size. The host is using it to identify which kind of Tundra it was.

Jeep Cherokee
Car

Jeep Cherokee

The Jeep Cherokee is an SUV, not a pickup truck. People use it for everyday driving, and some also modify it for off-road trails. In the podcast, they’re talking about a specific Cherokee that’s being built for that purpose.
