KYB SB164 Suspension Strut Bellows - Rear

KYB Strut Boot for Rear Suspension Protection

The KYB SB164 strut boot helps protect the rear strut shaft from dirt, dust, sand, salt, and other road debris. By covering the polished shaft, it helps reduce abrasive wear at the seal and bushing area on applications such as the Lincoln Continental, Lincoln Nautilus, and Lincoln MKX.

KYB Strut Boots are part of the KYB Strut Boots line, built for rear suspension service where shaft protection and travel control matter. The SB164 includes a poly foam travel-limiting bumper to help reduce bottoming-out impact and limit damage from extreme suspension movement.
