Differential Mount Bushing Set, Poly 75D – BMW E46 (M3), Z4 (M)

Product Description

Differential Mount Bushing Set, Poly 75D for BMW E46 (M3), Z4 (M). The stock rubber diff mount bushings deflect as torque moves through the drivetrain, which allows the differential to move. Upgrading your stock rubber diff bushings to our 75D polyurethane differential mount bushings will eliminate virtually all differential movement for increased 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.

These extremely hard race-spec 75D durometer polyurethane differential mount bushings are the hardest available (aside from solid aluminum) and 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 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 aluminum sleeves. Set of three. Engineered for a perfect fit. Read why our polyurethane bushings are the highest quality bushings available.
