10mm Rear Polyurethane Shock Mounts for BMW E30 E36 E46 Z3 Z4

These Aluminum Rear Shock Mounts (10mm) 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 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.

Features:

• High Performance - Eliminates deflection of factory shock mounts under load and reduces the negative effects from rear shock damping, especially with improved suspension and additional shock valves. Helps to keep the rear shock absorber in the proper position for its proper operation. Also improves ride experience by eliminating rear end knocking caused by rubber wear in the original rear shock mount.
• 85A Polyurethane bushings with superior performance - Polyurethane has less compression variability, high stability, shock resistance, and aging resistance. It is superior to the common rubber in the market.
• Reinforcement parts - Made of aluminum and steel. Prevents breakage above the rear shock absorbers.
• Perfect fit - 10mm hole pitch.
• Corrosion and abrasion resistant - Surface anodised.

IMPORTANT: The 10mm/12mm sizing refers to the inner diameter of the shock mount sleeve. The size of your shock dictates which size you need (OEM is 10mm; aftermarket shocks vary and must be measured). If you aren’t sure which size you need, measure the OD of the top threaded portion of the shock, or check with the manufacturer.

10mm (shock shaft diameter) fits standard shocks and some coilover systems such as for BMW OEM Shocks,For Bilstein PSS9/PSS10.For H&R Coilovers,For FK Coilovers,For Raceland,For ST Coilovers,For KW V1, V2, V3,For Koni Sport/Dinan and For All AST 4XXX/5XXX Series .
12mm fits racing coilovers such as for Tein（some), For MCS, for JRZ, For Ohlins and For TC Kline S/A or D/A. Does NOT fit convertible models.
