Bilstein B8 8100 ZoneControl R Front Shock Absorber - Ford F-250 / F-350 Super Duty 2005-2026

Bilstein B8 8100 ZoneControl R reservoir shocks are a direct fit, position sensitive solution for light trucks and SUVs. The double piston design carries two stages of rebound valving and delivers position sensitive rebound damping, which eliminates harsh suspension top-out and removes the need for an external limit strap. A 60mm large bore digressive piston widens the tuning range, giving comfort without surrendering control, and a 60mm remote reservoir adds oil capacity so damping stays consistent over rough terrain. Supplied with a bolt-on anodised reservoir chassis mount where applicable.
