ECS Performance Polyurethane Diff Bushing Set

Featuring a tough 95A durometer polyurethane and Black anodized 6061-T6 aluminum sleeve, our BMW E39 Performance Poly Dif Bushing eliminates the deflection factory rubber bushings permit. The connection between your right foot (and your seat) to the wheels is improved. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts.
