The SuperPro Rear Differential Pinion Mount Bushing Kit replaces the forward differential mount bushings, commonly known as pinion mount bushings. The original equipment manufacturer (OEM) units, made of soft rubber, are prone to rapid wear, especially under demanding use.
Worn bushings contribute to increased movement of the rear differential during load changes. Initially, this can result in a noticeable decrease in responsiveness, feeling slower and less precise. As the OEM bushings approach the end of their lifespan or fail, this can be accompanied by noise, vibration, and secondary movements under changing loads, particularly during acceleration and deceleration.
SuperPro's differential mount upgrades are designed to maintain OEM levels of noise, vibration, and harshness (NVH) isolation within the cabin, ensuring your vehicle retains its factory comfort. Simultaneously, performance is significantly enhanced due to the more accurate positioning of the differential across a wider range of conditions. The service life is also dramatically improved, as SuperPro materials maintain peak performance throughout their lifespan, unlike natural rubber, which gradually softens and degrades.
