Frequently Asked Questions
How can I tell if an adaptive shock is leaking?
Look for oil residue or wet spots on the shock body or mounting area. A leaking shock will show a film of hydraulic fluid on its surface, often collecting dirt and grime.
Does a leaking shock affect safety?
A leaking shock has reduced damping ability, which affects vehicle stability, braking distances, and tire contact with the road. It should be replaced as soon as practical.
Are aftermarket adaptive shocks available?
For many popular luxury vehicles, aftermarket adaptive shocks are available at lower cost than OEM parts. Ensure any aftermarket part is compatible with your vehicle suspension control system.
