Bilstein B8 8100 ZoneControl R 60mm Reservoir Shock Absorbers with Direct-Fit Chassis Mount and Hardware Kit

Upgrade your light truck or SUV with the Bilstein B8 8100 (ZoneControl R) suspension system, engineered to deliver position-sensitive rebound damping and superior heat dissipation. Unlike standard shocks, this 60mm absorber utilizes a double piston design and 2-stage rebound valving to eliminate harsh top-out events, removing the need for external limit straps while maintaining daily drive comfort.

The kit includes all necessary components for a complete installation, as evidenced by the included hardware layout: a bolt-on anodized reservoir chassis mount featuring heavy-duty black powder-coated brackets, a Bilstein-branded reservoir collar, rubber vibration bushings, and a comprehensive hardware kit. This direct-fit solution is designed for light trucks and SUVs, ensuring compatibility without fabrication.
