AKG Motorsport Rear Trailing Arm Bushings, Poly 75D – E36, E46, Z4

Product Description These BMW E36, E46, Z4 Polyurethane (75D) Rear Trailing Arm Bushings (RTAB) virtually eliminate movement of the rear trailing arms to prevent geometry changes – keeping alignment and handling consistent. In addition, our unique bushing design incorporates grease grooves for easy lubrication. The factory rubber rear trailing arm bushings are soft and wear out quickly, creating fluctuations in suspension geometry that adversely affects everything from cornering to braking stability. Virtually eliminate these issues with our BMW E36, E46, Z4 poly 75D rear trailing arm bushings (RTAB). These extremely hard, race-spec 75D durometer polyurethane BMW E36, E46, Z4 rear trailing arm bushings are the hardest available (aside from solid aluminum). They are the best option for race classes where solid bushings are not allowed, or for those who do not wish to deal with the issues that may arise when using solid metal bushings. This is the proper durometer for high horsepower and
