AKG Performance Parts for BMW

BMW Rear Upper Shock Mount Bushings, Poly 85A – E90, E92, E82

Part#: RSM82908

Product Description

These BMW E90, E92, E82 Polyurethane (85A) Rear Upper Shock Mount Bushings are true, performance rear shock mounts that drastically reduce the deflection that occurs with the factory upper rear shock mount bushings. The stock shock mount bushings deflect under load – negatively affecting the rear shock damping, especially with a modified suspension and increased shock valving. Upgrading your factory shock mount bushings to our BMW E90, E92, E82 polyurethane (85A) rear upper shock mount bushings will drastically reduce this movement, helping to keep the rear shock in place so that it may operate properly.

These medium 85A durometer polyurethane BMW E90, E82 upper rear shock mount bushings are our street-spec compound bushings (as opposed to our performance-spec 95A compound). They are designed for those who want to retain a relatively comfortable ride with slightly improved performance over the stock oem bushings. We recommend pairing these rear upper shock mount bushings with our BMW Poly Rear Lower Shock Mounts to eliminate movement at the bottom of the shock as well, for the ultimate in performance and reliability.

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 usually 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.

About Our 85A Polyurethane

Our U.S. Military Spec 85A durometer compound has elasticity and memory. This exclusive compound allows us to manufacture a bushing with superior performance characteristics that is free from the deformation which plastic bushings (Delrin, UHMW) are very prone to. Perfect for street-going cars which do not have large increases in horsepower over stock.

AKG bushings are the only performance bushings for BMW molded in the USA under ISO 9001:2015 certified quality standards – the gold standard in manufacturing. Our exclusive Mil-Spec polyurethane raw stock costs up to 5x that of the cheap poly and plastic used by others.
