speed of air pistons

They’re talking about a special piston setup that uses air/airflow to work. The claim is that it improves efficiency enough to save you money over time.

Term

fuel economy

Fuel economy is just how far you can drive on a tank of fuel. Higher fuel economy means you spend less on fuel for the same miles.

Term

torque

Torque is the engine’s pulling strength. More torque usually means the truck feels stronger, especially when towing or climbing.

Term

lead times

Lead time means how long you have to wait after you order something before it shows up. Short lead times help you avoid delays in repairs or builds.

Term

cranks

The crankshaft is the main spinning part inside the engine. It turns the pistons’ motion into the rotation that drives the wheels.

Term

valve train upgrades

The valve train controls when the engine’s intake and exhaust valves open and close. Upgrades can help the engine breathe better, especially when you’re pushing more power.

Term

rods

Rods are internal engine parts that connect the pistons to the crankshaft. Stronger rods can help an engine survive higher stress.

Term

lubricity

Lubricity means the fuel can “lubricate” the precision parts in a diesel engine. If the fuel doesn’t lubricate well, those parts wear out faster and repairs get expensive.

Brand

C-tane

C-tane is basically a way to talk about how easily diesel fuel ignites. Better ignition can mean smoother running and easier starts.

Concept

maintenance curve

It’s basically a plan for when to do routine service. If you follow that schedule, small problems are less likely to turn into big, costly repairs.

Concept

fuel up schedule

A “fuel up schedule” is a routine cadence for when you refuel, often used as a trigger for adding fuel treatments or additives. In this segment, it’s framed as the easy way to keep a maintenance-related step consistent.

Term

diesel fuel

Diesel fuel is what diesel engines burn. The quality of what you buy at the gas station can influence how smoothly the truck runs and what maintenance problems show up.

Term

35 inch tires

“35-inch tires” means the tires are about 35 inches tall. Bigger tires are often used for off-roading because they can help the truck clear obstacles, but they can also change how the truck drives and whether everything fits correctly.

Term

stock suspension

“Stock suspension” is the suspension the truck originally had when it left the factory. If it’s “not stock,” that means someone changed it—often to make it better for rough roads or to fit bigger tires.

Term

off-road suspension

“Off-road suspension” is suspension that’s designed for rough trails instead of smooth pavement. It usually helps the truck ride higher and absorb bigger bumps so the tires stay planted.

Brand

Mickey Thompson

Mickey Thompson is a company that makes tires, especially for off-road and performance use. The hosts are pointing out that even though it’s “just tires,” it has a strong off-road reputation.

Concept

mechanic shortage

A mechanic shortage is when there aren’t enough mechanics to handle all the repairs people need. If more mechanics retire than get replaced, trucks can end up waiting longer for service.

Topic

diesel space is changing very rapidly

They’re saying diesel trucks and how people work on them are changing fast. Newer technology means mechanics may need different skills than they used to.

Concept

diagnostics

Diagnostics is the process of figuring out what’s wrong with a diesel truck. A mechanic uses computer readings and tests to find the exact cause, so repairs are more accurate.

Term

6.7

The “6.7” means the engine is about 6.7 liters in size. Bigger diesel engines like this are usually chosen because they can pull heavy loads with strong low-end power.

Term

high output

“High output” means the engine is tuned or configured to produce more power and/or torque than a standard version. On diesel trucks, that typically translates to stronger towing and hauling performance.

Term

20 inch wheels

“20 inch wheels” just means the wheels are 20 inches across. Bigger wheels can change how the truck rides and how it looks.

Term

37 inch tires

“37 inch tires” means the tires are very large—often used for off-road capability. They can help with clearance, but they may also make the truck feel different and can impact efficiency.

Term

spares in the back of the bed
