Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

• Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
• 80A polyurethane isolation bushings for NVH control
• Accommodates 10mm, 12mm, or 14mm damper shafts
• Fully constrained shaft mount makes RSM blow out impossible
• Hard anodized 6061-T6 construction
• Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.
