Tarett Rear Coilover Conversion Kit for 1972-1989 Porsche 911 and 930 with Bilstein Shocks. (RSRRCOK911)

Tarett for Porsche Collection by MGC Suspensions


  • Product Description

      This cost effective alternative to buying threaded body rear shocks allows you to simply convert your current Bilstein shocks to coilovers for a fraction of the price.


      • Allows ride height to be adjusted with ease.
      • 2.25" ID coil springs allow for spring rates greater than what is available in torsion bar sizes.
      • Square threaded design is stronger and more resistant to dings, dirt, and binding associated with the traditional Bilstein RSR struts.
      • Square threads actually lock the spring perch in place under load, this is backed up by a nylon tipped set screw for extra security.
      • All components are anodized for great durability and appearance.

      A minor shock modification is required to support the threaded sleeve. We can perform this modification at no charge except the cost of shipping.

      Kit includes sleeves, upper hats (a $180 value), lower adjustable spring seats, and retainer rings to support the sleeves. Coil springs, shocks, and optional tender spring spacers sold separately.

      Fitment Notes:

      Fits all 911 Bilstein shocks on '72 to '89 911's and 930's.
