OEM Factory bushing are very soft and flexible, which allows the differential to move under hard driving conditions. Also, the factory configuration only includes 2 front bushings and 1 rear bushing, allowing the differential to flex excessively when bushings are worn. This excessive flex can lead to failure in the differential cover.

With the use of the ISR Performance multi-piece differential bushing you can help eliminate unecessary driveline movement and help prevent differential cover damage! The ISR Performance differential bushings use a multi-piece construciton which features a hardened Delrin bushing and an aluminum sleeve, and include a 4th bushing to further reinforce the differential.
