Shock Service Request Process

Shocks smooth out your ride by forcing special oil through ports and orifices inside the shock. Like engine oil, this shock oil is eventually broken down and loses some of its damping and lubricating qualities. Replacing this oil is a fairly inexpensive job and will make a big difference in performance.

How often service is needed depends on several factors, such as racing conditions, how often you ride, and how aggressively you ride. Your shocks should be serviced at least once a year under normal conditions.

If you feel that your shocks are not performing as well as when new, you probably just need to have them serviced. We are fully equipped to handle all service and repair work on your Penske Racing Shocks/Custom Axis Racing Shocks, and we can work with you to make any changes to help fine-tune them to your requirements.
