Differential Mount Bushing, Poly 85A for BMW E30, E36 318ti, Z3. The stock rubber diff mount bushing deflects as torque moves through the drivetrain, which allows the differential to move. Upgrading your stock rubber diff bushing to AKG's 85A polyurethane differential mount bushing will tighten up this differential movement for improved power transfer to the rear wheels. The material used for the diff mount bushing location(s) must match the material used for the subframe bushings.
This medium 85A durometer polyurethane differential mount bushing is our street-spec compound bushing (as opposed to AKG's performance-spec 95A compound). It is designed for those who want to retain a relatively comfortable ride with slightly improved performance over the stock oem bushings.
AKG's U.S. Military Spec 85A durometer compound has elasticity and memory. This exclusive compound allows AKG to manufacture a bushing with performance characteristics that are free from the deformation which plastic bushings (Delrin, UHMW) are very prone to.
Made of AKG's exlusive U.S. Military Spec polyurethane (85A hardness) with stainless steel sleeve. Engineered for a perfect fit. Read why AKG's polyurethane bushings are the highest quality bushings available
