Remove all springs (unless you want them tested) and mounting hardware before shipping. If you do not have tools to safely remove the springs yourself, ship them assembled. We will dismount and remount them for you. There is a $20.00 per shock charge to remove and reinstall springs that require the use of a spring compressor.
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.
