SuperPro 1990 Mazda Miata Base Rear Differential Mount Bushing Kit

Superpro is known for making well-built suspension and drivetrain components. If you're working on the rear end of your 1990-1997 or 1999-2005 Mazda Miata, this kit replaces the forward differential mount bushings, often called pinion mount bushings. The original rubber bushings can break down over time, especially with harder driving, leading to extra movement in the rear differential. This extra play can make your car feel less responsive when you get on and off the throttle, and worn bushings can also cause noise and vibration.

This kit uses Superpro's durable materials to keep the differential located more precisely, improving how the car feels when you change loads. Importantly, these bushings are designed to maintain the factory levels of comfort inside the cabin, so you won't get extra noise or vibration from the upgrade. They are built to last much longer than the original rubber, maintaining their performance over time instead of softening and degrading.
