Product Description

The SuperPro SPF2637K Rear Differential Pinion Mount Bush Kit replaces the factory rubber bushings at the front mounting point of the rear differential with precision-engineered polyurethane components. The upgraded bushings minimize differential movement during acceleration, shifting, and aggressive driving, resulting in improved drivetrain stability, more consistent power delivery, and enhanced vehicle control.

Designed for Nissan Skyline R32, R33, and R34 models, along with the S14/S15 Silvia, 200SX, and North American 240SX applications, this kit includes replacement polyurethane bushings, steel crush tubes, and washers for a complete installation. SuperPro's proprietary polyurethane offers exceptional durability and resistance to wear while maintaining excellent NVH characteristics, making it an ideal upgrade for both high-performance street vehicles and motorsport applications.
