Product Description
The BILSTEIN 24-285681 5100 Series Rear Shock Absorber is engineered specifically for 2014-2023 Ram 2500 4WD trucks with 0-2” of lift and without factory air suspension. Designed for diesel trucks that demand more from their suspension, this Bilstein B8 5100 shock delivers superior off-road capability, towing stability, and ride control.
Built with Bilstein’s monotube gas pressure design, the 5100 Series provides consistent, fade-free performance even under heavy loads and extreme conditions. The zinc-plated body resists corrosion while maintaining durability in harsh environments, making it ideal for work trucks and off-road builds.
The 46mm digressive piston with velocity-sensitive valving reacts instantly to changing terrain, providing firm control for lifted trucks while maintaining ride comfort. This shock is tuned specifically for Ram 2500 applications and accommodates increased suspension travel from lift kits.
Compared to standard shocks, the 5100 Series is designed for lifted applications and off-road use, offering improved control, reduced body roll, and enhanced handling for trucks running larger tires and aftermarket suspension systems.
