Differentials

Differentials improve engine performance and offer added traction when you want your 4x4 to take on corners and snaking trails with ease. Your differential is made up of a series of gears including the ring gear and pinion gear to synchronize the varying speeds your tires spin at during a turn. We carry an impressive selection of open, limited slip and torque-vectoring differentials with variations on design from top brands like Detroit, Eaton and Crown Automotive.

Differentials
Make sure your vehicle's axles have what they need whether you are looking for a Detroit locker for Toyota or Detroit lockers for a Jeep. Your differential goes from one that is a conventional open type to an axle of the full spool type. This ensures that both of your wheels are getting 100 percent power no matter where you're driving.

Why Your Differential Matters
The differential on your vehicle works to make sure that the wheels are able to rotate at different speeds while it also drives both of the wheels. If a car does not have a differential, both of the wheels have no choice but to rotate at an equal speed. When this part is present on a vehicle, it allows for a more effective and efficient ride because they are not forced into a rotation that is not optimal.
