The strut mount is a critical suspension component that provides a secure mounting point and pivot for your BMW's front strut. With higher mileage, the built-in bearing can wear out, leading to reduced suspension performance, increased noise, and compromised handling.

For optimal suspension function and durability, it’s recommended to replace the strut mounts whenever installing new front struts. Choose this premium replacement from Bremmen Parts for a reliable and long-lasting repair.

Rubber mounts in any position of a vehicle are usually designed with comfort and longevity in mind leaving performance as a sacrifice. This kind of sacrifice here at Turner just won't do, so we did what we do best and designed a solid monoball mount.

Our engineering team first wanted to tackle the issue with wear found on rubber mounts. Due to their combination of steel, rubber, and low mounting location, these mounts are a direct target for deterioration and failure. As they are positioned out in the open and exposed to the elements, bonded steel and rubber components inevitably hold moisture, separating as the steel bearing begins to rust. Our solution was to offer a rebuildable mount with a Teflon lined bearing for increased durability, combined with a blue anodized body and melonite coated bushing sleeves for corrosion resistance.

The performance side of these mounts is primarily found in the articulation allowed by the bearing. Rubber mounts do not allow for proper free damper movement, hindering shock performance. By eliminating the deflection found in factory rubber mounts and allowing full shock articulation, this solid monoball design eliminates slop and maximizes shock efficiency and performance, allowing for more predictable handling on the street or the track - with almost zero added noise, vibration, and harshness.

• Includes new hardware
• Made in USA

Housing:

• Billet CNC 6061-T6 aluminum housing, type II anodized for exceptional durability and corrosion resistance

Bearing:

• FK WSSX14T teflon lined spherical bearing
• 440C heat-treated stainless steel ball, 1 ⅜” ball dia.
• 17-4 PH heat-treated stainless steel race
• Self-lubricating PTFE liners are chemically bonded to the inner diameter of the race to offer a very high load-carrying capacity with greatly increased dynamic wear characteristics.
• Static Axial Load Rating: 10,800 lbs.
• Rod End Misalign Angle: 6 degrees

Bearing inserts:

• CNC machined 1144 steel, heat treated and melonite coated designed to maximize ball articulation while offering exceptional durability and corrosion resistance.

Elevate Your BMW's Performance with ECS Tuning's Ultimate Performance Rear Shock Mount Kit

ECS Tuning presents the Ultimate Performance Rear Shock Mount Kit, specifically designed to address recurring rear shock mount blowouts experienced by various BMW models, including the M3 and non-M 3 Series dating back to the E30 chassis in 1984. This innovative kit provides a long-term solution, ensuring optimal damper performance and longevity while eliminating rear clunking noises and handling issues caused by blown shock mounts.

Key Benefits:

• Solves rear shock mount blowout issues on BMW models
• Allows full articulation of rear dampers for improved performance
• Industry-first design with PTFE lined stainless steel monoball spherical bearing
• 80A polyurethane isolation bushings reduce noise, vibration, and harshness (NVH)
• Lower dust seal enhances bearing life by preventing road debris ingress
• Corrosion-resistant anodized 6061-T6 construction for durability
• Compatible with 10mm, 12mm, or 14mm damper shafts

Upgrade your BMW's rear shock mounts with ECS Tuning's Ultimate Performance Rear Shock Mount Kit, providing superior performance, reduced NVH, and increased bearing longevity for a more controlled and comfortable ride.

This upper shock tower strut mount is located at the top of the shock. We recommend inspecting or replacing these while replacing the rear shocks.

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.

Replacing your struts and shocks? Don't forget the bushings! The rubber mounts for the shocks will go bad over time, especially if you drive hard or the roads are particularly rough. The shock mounts locate the front struts and rear shocks to the car - providing a quiet and vibration-free buffer between the road and the cabin. Shock mounts and bushings can wear out just like any other rubber part on the car. This leads to more noise and harshness reaching the chassis and may complicate your new suspension install. When installing new shocks, that is the perfect time to also replace the mounts. There is no additional time to install them, no special tools required, and doesn't take any extra time! If you re-use the original mounts you have the risk of them failing before your next shock replacement, doubling your labor costs.
