Spiroloc Retaining Ring for Penske Eyelet Spherical Bearing

Spirolocs function like circlip retaining rings, but are preferred by many racers for the extra level of security they provide. This Spiroloc retainer is designed for the 1/2" bore x 1" OD spherical bearing used on many racing dampers, including Penske 8100 and Bilstein large body coil-overs. Requires no modification to the circlip groove. Sold individually.

If your shocks use either the original Penske spherical bearing (formerly Pegasus Part No. 8011-02) or the PTFE-Lined Spherical Bearing (Part No. 3071-8), you can use these Spirolocs in place of the C-clips.
