AKG Motorsport - BMW Rear Subframe And Diff Bushing Set, Poly 85A – E30

This BMW E30 Polyurethane (75D) Rear Subframe and Differential Mount Bushing Set eliminates virtually all subframe and differential movement for effective power transfer through the rear end to the wheels. Rear subframe bushings are also the first step in maintaining proper rear-end geometry and alignment. The stock rubber subframe and differential bushings deflect as torque moves through the drivetrain, allowing the entire rear end to move. Virtually eliminate rear subframe movement and allow your diff to operate effectively with our BMW E30 poly 75d rear subframe and differential bushing set.

These extremely hard, race-spec 75D durometer polyurethane subframe and diff 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 aluminum sleeves. Engineered for a perfect fit. Set of two subframe bushings and one differential mount bushing.
