If you are removing or changing the front struts or springs or replacing the upper strut mount, NOW is the perfect time to replace this upper spring perch. BMW calls it a "upper spring pocket with axial cage bearing". It's really the upper spring plate with the radial bearing set sandwiched between two plastic collars. The bearing is there to allow the spring to rotate a little before going into a bind. If there are popping noises coming from the front strut it's probably because this bearing set is worn or missing. The bearing insert is a common wear item becoming noisy, gritty, or will just fail completely. You won't feel that they're bad from driving the car but you may hear clunking or popping sounds from the front struts. You can replace the rubber mounts on the car but don't leave this part out! It may be just as worn and you won't want to put them back in the car. These are sold individually, so be sure to get two for your car.

The radial bearing set is used in some of our camber plate designs. It's compact, light weight, easy to replace, and inexpensive. It's an excellent alternative to pricey and obscure ball bearing sets found in other camber plates.

1994-2001 E38 740i, 740iL, 750iL

BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

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.

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.
