Rear shock mounts are tasked with securing shocks while absorbing noise, vibration and harshness that would otherwise be associated with a solid mount. Factory rubber bushings are a compromise between a cushy ride and responsive handling.

Powerflex polyurethane rear shock mounts are firmer than OEM bushings, resulting in better handling, a more responsive rear-end, and more efficient suspension articulation - all with minimal sacrifice to ride quality.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Made in the USAIf you're installing racing rear shocks with a spherical bearing end you will need this adapter mount for the top of the rear shock. Spherical or rod-end bearings are common on race shocks but they are somewhat universal and mounts are not usually included. We designed and engineered these mounts for our E9X M3 and E90 328i IMSA/CTSCC racecars. Our cacing upper shock mount is machined out of aircraft grade aluminum with a tough anodize finish and high grade hardware. Due to the wide variety of spherical bearings and rod-ends found on race shocks, the bushing kit is sold seperately (see chart for bushing sizes).
