What's That Sound
One of the best indicators of troubles with your differential is unusual sounds from your Jeep. Both clicking when firing up the engine and a whirring noise in the rear when operating can be signs that your differential is shot, or about to be, and that it's time to start looking to replace it with a new and improved system. The whirring will become more severe, even reaching howling levels, if you continue to leave it unchecked. Don't wait until your failing differential causes you to lose traction at a vital time before your replace it.

ARB Air Locking Differentials
For added traction, you can do no better than an ARB differential. The ARB Air Locker™ is designed with aerospace-grade high alloy wheels, the strongest and most functional differentials on the market. As a bonus, engineers at ARB include Timed Gear Technology to guarantee the gear teeth interlock correctly and maintain the right amount of force. Rotation force loads more consistently and uniformly due to the added number of pinion gears to the design of the ARB differentials. Check out our selection of high quality performance differentials, one of the largest collections out there, and get your entire ARB Air Locker™ install kit from us, too.

ARB Differential Covers
Intended to keep your ARB Air Locker™ safe and improve its lifespan, differential covers are produced with a highly durable and malleable iron. The engineers at ARB improved upon the standard design so much, in fact, that their design does not only serve its intended purpose, but even enhances the durability of smaller axle assemblies. At 4 Wheel Parts, all our ARB differential covers come with a drain plug and magnetic dipstick.
