These BMW E30, E36, E46, Z3, Z4 Aluminum Rear Shock Mounts (12mm) with Poly Bushings are true, performance rear shock mounts that virtually eliminate the deflection that occurs with the factory shock mounts. The stock rubber upper shock mounts deflect under load negatively affecting the rear shock damping, especially with a modified suspension and increased shock valving.Upgrading your stock rear shock mounts to our BMW E30, E36, E46, Z3, Z4 aluminum rear shock mounts with poly bushings will drastically reduce this movement, helping to keep the rear shock in place so that it may operate properly. These may also be paired with our BMW Rear Shock Mount Reinforcements.

Made of solid CNCd 7075-T6 aluminum with U.S. Military Spec 12mm polyurethane bushings (replaceable). Hard anodized for corrosion resistance.Set of two shock mounts with heavy-duty stainless hardware.

Original AKG design.
