Product Description

The SuperPro SPF2433K Rear Differential Support Bracket Mount Bushing Kit replaces the factory rubber differential mount bushings with durable, high-performance polyurethane components. The upgraded bushings provide improved control of differential movement during hard acceleration, gear changes, and spirited driving while maintaining excellent NVH characteristics for everyday street use.

Designed specifically for the Subaru GD/GG Impreza platform and the Saab 9-2X, this kit improves drivetrain stability, enhances power transfer, and offers substantially greater durability than the original rubber bushings. Each kit includes precision-engineered polyurethane bushings and steel crush tubes for a direct-fit installation using the original mounting hardware.
