Koni Service

Koni Service

KONI shock rebuild cost starts at approximately $250 each for single adjustable and $325 for dual adjustable pending inspection and evaluation of your KONI shocks. Internal hard parts will be additional cost to service fee if replacement parts are required. If KONI still manufacture shocks for your car we recommend replacement with new KONI shocks Vs. rebuilding.

If you have KONI racing 3012/2812/8211/8212 or historic shocks no longer available new we can rebuild them for you.

You may also visit our Shop at Sonoma Raceway to drop off your shocks and discuss your suspension requirements. We are open Monday through Friday, 8.00am to 5.00pm. Call in advance for Raceway access during race weekends.
