Product Description
The BILSTEIN 25-311891 5160 Series Shock Absorber with Remote Reservoir is a high-performance rear shock upgrade designed for 2001-2010 Chevrolet Silverado and GMC Sierra 2500HD/3500HD 4WD trucks with 0–2 inches of lift. Built to handle the demands of diesel trucks, towing, and off-road use, this shock delivers consistent performance, improved ride quality, and maximum durability.
Engineered with Bilstein’s 46mm monotube gas pressure design and paired with a remote reservoir, this shock significantly increases oil capacity and cooling efficiency. The result is reduced shock fade and consistent damping performance during heavy hauling, rough terrain, and extended off-road driving.
The velocity-sensitive digressive piston automatically adjusts to changing road conditions, providing a smooth highway ride while maintaining firm control in off-road or high-load situations. This makes the Bilstein 5160 Series one of the best upgrades for lifted GM HD trucks needing both comfort and performance.
