Your Shocks Are Losing Performance Faster Than You Think

  • Shock oil breaks down under heat and use, reducing damping performance over time.
  • Shims can bend from heavy use or rough conditions, leading to major losses in control and consistency.
  • Most handling issues aren’t setup problems. They’re worn shocks.
  • If your vehicle feels different, your shocks are likely the reason.

Frequently Asked Questions

How often should I service my shocks?

Service intervals depend on how often and how hard the shocks are used. As a general guideline, Penske recommends regular inspection and service for any shock that sees consistent track, racing, or off-road use. Fresh oil, seals, and internal components help maintain consistent damping performance and maximize shock life. If you're unsure whether your shocks are due for service, contact us and we'll help determine the appropriate interval for your application.

Turnaround time varies based on workload, seasonality, and the condition of the shocks. Standard service is typically completed within a few business days to a few weeks after the shocks are received. 15 Business days should be an expected time frame, but repairs requiring replacement parts may take longer. If you have an upcoming race or event, let us know and we'll do our best to accommodate your schedule.

 

If we find damaged shafts, bodies, reservoirs, adjusters, or other components that require replacement, we'll contact you before any additional work is performed. Our technicians will inspect the shocks, provide recommendations, and supply an estimate for any repairs beyond the standard service package. No additional charges will be made without your approval.

Not necessarily. Handling concerns can be caused by shock wear, but they can also result from spring rates, ride height, chassis setup, tire condition, alignment, or other vehicle dynamics factors. If you're experiencing a performance issue, include detailed notes with your service request. Our team will inspect the shocks and help determine whether the issue is shock-related or if additional setup changes should be considered.

Without rigid templates, you can build the exact type of website necessary to hit your website performnace goals.

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.
