All suspension parts suffer from wear and tear and need repairs at some point. The streets can be filled with pot holes and debris that can wear out your suspension parts, and that’s why we have performance suspension parts available for purchase. We offer replacement dampers, aka shocks, for your coilovers. Bring your old kit back to feeling like new when you replace old worn-out parts. There are performance suspension parts for every make and model that we sell parts for. They all come with the same limited warranty that all our coilovers and air suspension do. If you need help picking the correct part, please reach out to customer service. Get it low and get it right with Function and Form.
