Rogue Engineering Rear Shock Mounts will make your rear end clunk a thing of the past. These high-quality and easily-serviceable rear shock mounts make you wish the factory had put this much effort into designing the OE parts.

BMW's factory rear shock mounts are designed with soft rubber in order to provide the quietest ride possible. Unfortunately, that means they're not very durable. Upgrading to OE E46 M3 rear mounts for your E30, E36, or E46 is a popular choice, but the factory design is simply week and known to fail, resulting in squeaking, rattling, clunking, and deflection of the rear shock mount. That's not only annoying, but it means your rear suspension isn't working optimally.

Rogue's RSMs are machined from 6061-T6 aluminum with Shore A 65 durometer rubber bushings (approximately 30% stiffer than the factory bushings) to allow for some level of street comfort. The design makes it impossible for the bushings to "pop out" like the factory mounts do when they fail. The bushings are also replaceable, so you can change just the bushing material instead of the entire mount. Compressions washers and spacers are made of 303 stainless steel for corrosion resistance, and all other hardware is either Grade 8 or better, treated with a yellow zinc plate for corrosion resistance.

Protection plus Quick Installation/Removal
A key feature of these RSMs is the reinforcement assembly that secures the rear shock mount to the vehicle, protecting against the rear shock from ripping out the sheet metal.

They also incorporate a bottom-mount design, so it only requires removing the two nuts and the single bolt at the bottom of the shock for removing dampers. You no longer need to disassemble the trunk area to gain access!

The Rogue Engineering Rear Shock Mounts are designed for standard 10mm rear shocks, but can also be used with 12mm adjustable race shocks with the use of optional washers.
