Product Description

The Bilstein 25-311822 B8 5160 Series Rear Shock Absorber is engineered for lifted Ford Super Duty trucks, specifically the 1999-2016 F-250 and F-350 4WD models with 3-5" rear lift applications. Featuring a monotube gas-pressurized design with a remote reservoir, this high-performance shock delivers superior damping control and heat dissipation for rough terrain and heavy duty use. The 46 mm digressive piston valving is tuned for the demands of lifted heavy-duty rear suspension dynamics, providing enhanced wheel control, improved ride quality, and reduced shock fade.

Built with a robust zinc-plated finish for corrosion resistance and including a 360° swivel banjo hose fitting with billet reservoir clamp, the 25-311822 installs using OE mounting locations without requiring extensive modifications. Designed as a direct-fit performance upgrade, it's ideal for Super Duty owners seeking reliable, fluid damping performance and improved off-road capability in lifted applications.
