The Prothane universal shock bushing (12mm ID) for Bilstein shocks in red is a replacement rubber-urethane isolator that fits shocks with a 12mm mounting diameter. It provides a cushioned, wear-resistant interface between the shock and its mount, helping reduce metal-to-metal contact. Use it where a 12mm inner diameter bushing is required for Bilstein-compatible shock applications and fit as part of standard shock servicing.
