Home/Engine & Driveline

Engine & Driveline

This department is the mechanical side of the catalogue: gaskets and seals, clutches and flywheels, differential and axle parts, engine internals, forced induction, transmission and transfer case parts, and timing components. Gaskets make up most of it, largely from SCE Gaskets. Clutch parts come from Advanced Clutch, Centerforce and Clutch Masters, and Edelbrock, Motive Gear and PRW fill in the engine and gear side.

Much of the fitment points at classic and performance cars rather than trucks: the Ford Mustang, Chevrolet Camaro, Chevrolet Corvette, Ford Fairlane, Ford Torino, Ford Galaxie 500, Mercury Cougar and Chevrolet Impala, alongside the Ford F-150. Rugged Ridge, ARB and Crown Automotive add off-road driveline parts.

Pick the section by the job. For a leak or a teardown, match gaskets and seals to the engine rather than only the car, since one model was often built with several engines. For a clutch, decide how much torque it has to hold and how the car is driven; multi-disc designs such as the Clutch Masters twin-disc and triple-disc units spread the load over more friction surfaces. The small parts are sold separately too, including pilot bushings, release bearings, hydraulic lines and fittings.

For axles, Motive Gear sells the shims, spacers and setup kits used when fitting a new ring and pinion, where correct pinion depth and backlash are what keep new gears quiet. PRW main girdle stud kits and other internals are for engines that are already apart. Each product page lists the years, makes and models it fits. To narrow the grid, browse differential and axle, engine internals or transmission and transfer case.

From the air box to the axles — SCE Gaskets, Advanced Clutch, Edelbrock and more. Engine components, gaskets and seals, clutches and flywheels, differentials, gears and the hardware that ties them together.

Most of what sits here is a repair or a rebuild rather than an upgrade, and the two want different things from you. A rebuild wants exact specification: bore, stroke, bearing size, gasket thickness and the tolerances your machinist gave you. An upgrade wants a matched set — a clutch that suits the torque you now make, gears that suit the tire diameter you now run, a cooler sized for the way the vehicle is actually used.

Gear ratio is the one most often left too late. Fitting substantially taller tires without regearing costs throttle response, shift quality and fuel economy all at once, and the axle does not care that the tires looked right.

Many listings in this department carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.

Working by system. On the engine itself: gaskets and seals for a leak or a rebuild, engine internals and engine hardware and fasteners once the short block is apart, timing components on interval. Behind it: clutch and flywheel matched to the torque you now make, differentials and axles when tire diameter has outgrown the gear ratio, and transmission and transfer case parts between the two.
