AKG Performance Parts for BMW

BMW Differential Bushing, Poly 95A – E30, E36 318ti, Z3

Part#: DM309

Product Description

This BMW E30, E36 318ti, Z3 Polyurethane (95A) Differential (Diff) Mount Bushing significantly reduces differential movement for improved power transfer to the rear wheels. The stock rubber diff bushing deflects as torque moves through the drivetrain, which allows the differential to move. Reduce this movement and allow your diff to operate more effectively with our BMW E30, E36 318ti, Z3 poly 95A differential bushing.

This medium-hard 95A durometer polyurethane BMW E30 diff mount bushing is our performance-spec compound bushing (as opposed to our race-spec 75D compound). It is designed for those who want a noticeable increase in performance out of their BMW, but would still like to retain as much of a comfortable ride as possible – such as with a daily driver. Remember: the material used for the diff mount bushing location(s) must match the material used for the subframe bushings.

About Our 95A Polyurethane

Our U.S. Military Spec 95A durometer compound is hard, yet slightly pliable – with elasticity and memory. This exclusive compound allows us to manufacture a bushing with high performance characteristics which is free from the deformation that plastic bushings (Delrin, UHMW) are very prone to. 

AKG bushings are the only performance bushings for BMW molded in the USA under ISO 9001:2015 certified quality standards – the gold standard in manufacturing. Our exclusive Mil-Spec polyurethane raw stock costs up to 5x that of the cheap poly and plastic used by others. All of our bushings are 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.
