Engine & Drivetrain

Customer Guides

The internal combustion engine provides the power to drive the vehicle’s wheels and the drivetrain is made up of components that transfer this power to the wheels.

Car engines can be classified by fuel type (gasoline, diesel), number of cylinders (4, 6, 8, 10), arrangement of cylinders (inline, flat, V-type), Valve train type (OHV, OHC, DOHC), and to a lesser extent cooling system type (air, liquid). The major parts of the engine include the lower cylinder block, upper cylinder head(s), and the cooling & lubricating systems. If properly maintained, the engine will last many years before a rebuild or replacement is necessary. We offer a complete line of quality engine components from gaskets and timing belt kits to oil pans and engine mounts.


The drivetrain consists of the transmission, clutch, driveshafts, axles, transfer cases, differentials, and wheel hubs & bearings. All of these components are very durable, but may need periodic maintenance to extend their life. If you hear clunking and whining sounds or feel vibrations, searching our comprehensive line of drivetrain components may be necessary.
