The SuperPro Rear Differential Pinion Mount Lower Bushing Kit replaces the forward differential mount bushings, commonly known as the pinion mount bushings. Original equipment manufacturer (OEM) units are typically made of soft rubber, which can degrade relatively quickly, with wear accelerating under demanding use.
Worn bushings contribute to increased movement of the rear differential during load changes. This can result in:
SuperPro's differential mount upgrades are designed to maintain OEM levels of noise, vibration, and harshness (NVH) isolation within the cabin, preserving your vehicle's factory comfort. Simultaneously, performance is significantly enhanced due to the differential being more accurately positioned across various driving conditions. The service life of these bushings is also dramatically improved, as SuperPro materials maintain peak performance throughout their lifespan, unlike natural rubber which can soften and degrade over time.
