Turner Motorsport Lower Rear Shock/Strut Mounts – Spherical Bearing Monoball Pillowball – Pair – BMW 3 Series E90/E91/E92/E93 & 1 Series E82/E88 (Non-M, Stud-Style) – Rear Damper Bush Upgrade 128i 135i 325i 328i 330i 335i 335d

Transform your BMW’s rear suspension with Turner Motorsport spherical bearing rear damper mounts

Upgrade the weak factory rubber bush at the bottom of the rear shock absorber to a motorsport-grade pillow ball solution that unlocks precision, grip and durability. These CNC machined aluminium mounts replace the compliant OE bushing at the rear control arm with a PTFE-lined spherical bearing, giving your damper true articulation, sharper response and consistent performance on fast road and track day use with minimal increase in NVH.

Why you will feel the difference

• Direct, rigid connection at the lower shock point for cleaner damping control and improved traction out of corners
• Low-friction articulation reduces side loading on the shock body and helps the damper do its job properly
• Eliminates bushing squirm and unwanted deflection for predictable handling and confidence at the limit
• Keeps the shock in the original location for correct geometry and alignment

Built to outlast the OE bushing

• Billet CNC 6061-T6 aluminium bodies, type II anodised for excellent corrosion resistance
• FK WSSX14T PTFE-lined spherical bearing with 440C heat-treated stainless ball and 17-4 PH heat-treated stainless race
• Static axial load rating 10,800 lbs and 6 degrees misalignment capability
• CNC machined 1144 steel bearing inserts, heat treated and melonite coated for strength and durability
• Supplied as a matched pair with new hardware
• Fully rebuildable using readily available bearings – buy once, service when needed
• Made in USA quality

Real-world results

We run these on our own cars and customers consistently report a crisper rear end, better stability over bumps and more immediate response under braking and turn-in. If you are chasing a more connected feel from your BMW’s chassis, this is a high-impact upgrade.

Compatibility and applications

For BMW models using the standard stud-type lower rear shock interface. Not for M models that use an eyelet style lower mount.

• BMW 1 Series E82 and E88: 128i N52, 135i N54, 135i N55
• BMW 3 Series E90, E91, E92, E93: 325i, 325xi, 328i, 328xi, 330i, 330xi, 335i N54, 335i N55, 335xi N54, 335xi N55, 335is N54, 335d M57
