• Features & Benefits

    Bilstein B8 8100 (ZoneControl R) reservoir shock absorbers are a direct fit, position sensitive solution designed for light trucks and SUVs. ZoneControl R is a revolutionary technology delivering position sensitive rebound damping which eliminates harsh suspension top-out events and the need for an external limit strap. The system incorporates a double piston design, offering 2 stages of rebound valving and is supplied with a remote reservoir for increased cooling and an accompanied, bolt-on anodized reservoir chassis mount where applicable. Bilstein B8 8100 (ZoneControl R) position sensitive shocks will offer unparalleled ride comfort during every day driving combined with maximum control over large suspension inputs.
