Performance

B1 is Bilstein's suspension service range — the protection kits, bump stops, dust covers and strut support bearings that sit around the damper. They are wear parts: a collapsed bump stop or split dust cover lets grit onto the piston rod and will kill a new damper early. Built to the same standards as the dampers they protect, and worth replacing at the same time.

What's Included

One protection kit for a single damper — bump stop and dust cover. It covers one corner, so order two per axle. The damper itself is not included.

Warranty

Backed by Bilstein's manufacturer warranty against defects in materials and workmanship. These are wear parts: cover is against manufacturing defects, not against the wear they are fitted to absorb.
