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.

Replaces OE part #: 33526768544

Key Benefits:

• Monoball rear lower shock mount eliminates unwanted deflection, maximizing shock efficiency and performance.
• Allows full shock body articulation for low friction movement and reduced side loading and improved shock wear.
• Designed to work with stock non-M taper seat stud style shocks (not M eyelet mount type).
• Maintains OE shock position

Design features:

• Rebuildable using off the shelf bearings - these are the last rear shock mounts you’ll need to buy
• 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.

If you're installing racing rear shocks with a spherical bearing end you will need this adapter mount for the top of the rear shock. Spherical or rod-end bearings are common on race shocks but they are somewhat universal and mounts are not usually included. We designed and engineered these mounts for our E9X M3 and E90 328i IMSA/CTSCC racecars. Our cacing upper shock mount is machined out of aircraft grade aluminum with a tough anodize finish and high grade hardware. Due to the wide variety of spherical bearings and rod-ends found on race shocks, the bushing kit is sold seperately (see chart for bushing sizes).
