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.

Because of all of this, it is important that you do not wait any longer to get the necessary work done to restore the optimal efficiency and drivability of your vehicle.

Engine power follows the path of least resistance. That's why one wheel spins freely when you are stuck in the mud. Without grip on the turf, your horsepower escapes in a whirl of muck. Jeep differential lockers keep the power output balanced across your axles. Upgrade your driveline, and make sure the tires that grip get the power they need.

Why Aren't Axles Solid?
You like to turn corners sometimes, don't you? When you drive your Jeep around a bend in the road the inside wheels must spin at a slightly slower speed than the outside wheels. The distance around the arc of the curve is farther for the on the outer edge than on the inside edge of the curve.

Your differential allows just enough speed variance between the wheels to keep your vehicle stable. The problem is that power from your engine can escape through the less efficient side, but a solid axle would be a nightmare to drive on the pavement. You wouldn't lose efficiency, but your tires would drag around corners and wear out. This is hard on the suspension and body as well.

The Best of Both Worlds
A limited slip differential solves a lot of problems. They allow enough play at low speeds to facilitate normal driving. At high rotational speeds, they mechanically lock in place. Both sides of the axles are firmly joined together providing even distribution of power to both wheels. When stuck in the mud, linking the axles together provides power to both wheels.

Selectable lockers are similar, but these can be manually activated. You decide when your axles are locked together. This feature comes in handy when fine control of your Jeep is needed to navigate tricky terrain. Get clear of the muck and slop when the wheel with grip can do the work for you.
