ECS complete polyurethane performance differential bushing set. 95A-durometer red polyurethane bushings with black-anodized 6061-T6 aluminum sleeves replace the factory rubber differential mounts, removing deflection from the driveline for crisper throttle response and reduced wheel hop under hard acceleration.

Fitment: BMW 1/3 Series - E82/E88, E90/E91/E92/E93 chassis (confirm exact differential/engine at checkout).
