AKG Performance Parts for BMW

BMW Rear Trailing Arm Bushings, Poly 75D – E30, Z3, 318ti, 2002

Part#: RTAB30D

Product Description

These BMW E30, 318ti, Z3, 2002 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 E30, 318ti, Z3, 2002 poly 75D rear trailing arm bushings (RTAB).

These extremely hard, race-spec 75D durometer polyurethane BMW E30, Z3 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/or big grip cars. 

About Our 75D Polyurethane

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.

AKG bushings are the only aftermarket bushings for BMW molded in the USA in accordance to ISO 9001:2015 certified standards – the gold standard in manufacturing. Our exclusive polyurethane raw stock costs up to 5x that of the cheap generic poly and plastic used by others. It is formed with our very own precision molds through a meticulous, state of the art molding process – providing the quality, reliability and consistent performance our parts are known for.
