Spring seats play a critical role in your suspension system by providing a cushioned interface between the coil spring and the strut or shock body. Over time, the original rubber or polyurethane material hardens and cracks, leading to increased road noise, vibration, and compromised suspension performance. The KYB SM5718 spring seat restores the isolation properties your suspension needs for a quiet, comfortable ride while maintaining precise handling characteristics.

When you choose KYB spring seats, you're selecting components built to the same specifications as the parts originally installed on your vehicle.
