Bilstein B8 5160 Series Shock Absorber (25-311815) – Front, for 4–6" Lift

Upgrade the front suspension on your lifted Ford Super Duty with the Bilstein B8 5160 Series remote reservoir shock absorber (part #25-311815). Built specifically for trucks running 4–6" of front lift, this monotube shock delivers consistent, fade-free damping whether you’re towing, daily driving, or tackling rough off-road terrain.

Key Benefits

The remote reservoir significantly increases oil capacity and improves heat dissipation, so performance stays strong even under sustained hard use. Velocity-sensitive digressive valving is application-tuned to react instantly to changing road or trail conditions, giving better control, reduced body roll, and improved wheel travel compared with stock or basic shocks. A 360° swivel banjo hose fitting allows clean, low-profile reservoir mounting, and the zinc-plated body resists corrosion in harsh environments.
