Truck Engine & Drivetrain Components

Engine gaskets and seals, intake piping, starting motor, alternators, and starters are all important parts of the engine and drivetrain. Whether your truck needs a new exhaust pipe elbow or a new fuel line, we at Big Rig World can help you get the right parts for your Semi’s make and model.

Engine Components, Alternators, & Starters 

One of the most important components of the engine is the engine gasket and its seal. Engine gaskets & seals are critical to the engine's overall function, and they seal the engine's engine and cylinder head. In addition, the intake piping, fuel lines, and exhaust pipe elbows need to be inspected and replaced as needed. You can get the specified gasket, seal, and O-ring to resolve oil leakage, engine installation and engine failure issues in your truck. We also sell turbos, engine control units, rebuild kits and more.

We carry a wide variety of alternators, starters, and components for Peterbilt, Kenworth, and other heavy-duty trucks. Whether you need a Bosch alternator for your Paccard or a starting motor for your Cummins, we've got you covered. Our alternators and starters are made with the highest quality materials, designed to last, and are designed to fit your specific truck's engine.

Air & Fuel System Components

It's important to keep your truck's air fuel system in good condition by regularly cleaning and replacing the air tubes, intake piping, and other parts.

The Peterbilt, Kenworth, and other heavy-duty trucks use a similar air fuel system. The system includes fuel lines, intake piping, air tubes and pipes. All of these parts need to be cleaned and replaced regularly to ensure smooth running and efficient fuel consumption.
