Installation Notes and Tips

KYB recommends installing new strut mounts, part number SM5361, to reduce noise and vibration, and a KYB strut boot, part number SB103, to help protect the strut from dirt, debris, and salt. Verify compressed length, extended length, stroke, and upper mount thread size before installation.
