Made in the USA These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

Must re-use factory cupped washers!

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.

Powerflex's new Rear Lower Shock Mounting Bushing and Bracket kit offers a stout lower anchor for even the most radical motorsport-derived shocks and coilovers.

These new bushings also feature CNC-machined 6082 aluminum brackets that help enhance longevity and weight reduction when compared with cheaper imitations. NOTE: 80A durometer bushings are intended for both street and track use and will result in a slight increase in NVH versus stock rubber bushings.
