SuperPro 1990 Mazda Miata Base Rear Differential Mount Insert Bushing Kit

SuperPro 1990 Mazda Miata Base Rear Differential Mount Insert Bushing Kit This kit replaces the forward differential mount bushings, known as the pinion mount bushings. The OEM units are made of soft rubber and tend to break down quickly, especially under heavy use. Worn bushings allow increased movement of the rear differential under changing loads. This can initially be felt as slower and less responsive handling. As the OEM bushings wear out, it can lead to noise, vibration, and secondary movements under changing loads, particularly during acceleration and deceleration. SuperPro's differential mount upgrades maintain OEM levels of noise, vibration, and harshness isolation in the cabin, preserving the factory comfort levels. At the same time, performance is significantly improved with the differential more accurately located under a wider range of conditions. The service life is dramatically extended, with materials maintaining peak performance throughout their lifespan, unlike natural rubber which softens and degrades over time.
