Our 12mm Spherical Rear Shock Mounts are highly recommended if you have high-quality performance shocks with 12mm shock shafts on your car. If you currently have rubber, polyurethane or upgraded non-solid rear shock mounts, you aren't getting your money's worth - our spherical mounts are the perfect solution.

Your dampers are designed to precisely control all suspension movement, but typical performance rear shock mounts allow approximately 1/2" of uncontrolled movement as the upper shaft mount flexes and moves. With the average road surface imperfection rate of change means you are giving up a lot of control and potential grip. You paid for those shocks, you should make them do the work!

Our 12mm Spherical Rear Mounts have a precision Aurora bearing installed in our billet aluminum carrier, which is slotted to allow for additional tire clearance if needed. The included stainless steel reinforcement plate also makes one-person installation a breeze. 

Fits all E46, E36, Z3, and Z4 models. Some convertibles will require mounting the reinforcement plate underneath depending on clearance. 

Shock Shaft Note: Most adjustable shocks will use a 12mm mount including MCS, KONI Sport, JRZ, etc. Most non-adjustable shocks will have a 10mm shaft diameter including OE, Bilstein, KONI non-adjustable. This mount is also available with a 10mm bearing (see additional products below).
  • Highly recommended for use with all high-quality rear shocks
  • Allow your dampers to work properly
  • Aurora bearing in a BW billet aluminum housing
  • Slotted for tire clearance
  • Easy one-person installation
Gaskets are recommended, but are not included.
