The Bilstein 25-268645 Rear B8 5160 Reservoir Shock Absorber is engineered to enhance the suspension performance of lifted 4WD trucks and SUVs. Designed as a direct fit solution, this shock absorber features a remote reservoir that significantly increases oil capacity, leading to improved heat dissipation and damping sensitivity. The monotube design ensures consistent, fade-free performance, while the velocity-sensitive digressive valving provides responsive damping tailored to each specific application. The 360-degree swivel banjo hose fitting allows for a clean, low-profile installation, and the billet reservoir clamp ensures secure mounting. With a collapsed length of 16.75 inches and an extended length of 24.96 inches, this shock absorber is suitable for rear lift heights of 0-1 inches. It is compatible with 4WD vehicles and is sold individually. The shock absorber is finished with a zinc plating for enhanced durability and corrosion resistance.
