AKG Performance Parts for BMW

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

Part#: RTAB36D

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 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.

Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a bushing that has virtually the same performance as a solid bushing, but without the harshness on the chassis associated with solid metal bushings. Likewise, its elasticity and memory means they are also free from deformation which plastic bushings (Delrin, UHMW) are very prone to.

Made of our exclusive U.S. Military Spec polyurethane (75D hardness) with stainless steel sleeves. Engineered for a perfect fit. Set of four. Read why our polyurethane bushings are the highest quality bushings available.
