Product Information

The suspension air struts use a shock body with an adjustable airbag that acts as the spring to support the weight of the vehicle. Air suspension provides for dynamic suspension tuning that adapts to changing road conditions to enhance the performance and driving characteristics of your Cayenne. A common failure point on an air strut is an air leak through a punctured air spring, or a leaking air spring seal or fitting. The air upper and lower strut mounts use rubber bushings to absorb impact and over time the rubber can stretch, degrade, and oxidize leading to clunking over bumps.

WARNING: Proposition 65 information
Air Suspension Spring

An air suspension spring (also called an air spring or airbag) is a flexible rubber and fabric component used in place of traditional coil springs. It is inflated with compressed air to support the vehicle’s weight and adjust ride height. Air springs are commonly found in luxury cars, SUVs, and heavy-duty vehicles.

Air Suspension Spring Failure Symptoms
  • Vehicle sagging – one corner, one side, or the whole car sits lower than normal.
  • Rough or bouncy ride – loss of cushioning, making the vehicle feel harsh over bumps.
  • Air compressor running constantly – the system tries to compensate for leaking or failed air springs.

Questions & Answers

Ask a question
Question Posted by a customer
Vehicle is low on both sides in the front, do I need to install two struts for proper repair?
Answer (Posted by FCP Euro Products Team)
It is always recommended to replace both sides when replacing worn suspension components, but do keep in mind you may have other issues causing problems with the front air system and should potentially check the system (air lines, fittings, control issues etc) before replacing specific components.
