Bilstein B8 5160 Remote Reservoir Shock Absorber 25-336689

The Bilstein B8 5160 remote reservoir shock absorber, part number 25-336689, is engineered as a direct-fit suspension upgrade for lifted light trucks and SUVs. Designed for demanding off-road use, this shock combines a remote reservoir with Bilstein’s proven monotube construction to increase cooling capacity, support greater wheel travel, and maintain consistent damping performance during extended driving. The application-specific velocity-sensitive digressive valving helps provide responsive control on changing terrain while supporting a confident ride on and off the road.
A 46mm monotube piston delivers consistent, fade-resistant performance across a wide range of conditions. The shock features non-adjustable damping, a zinc-plated finish, a smooth non-coilover body, and a 14mm shaft. Its 360-degree swivel banjo hose fitting helps simplify routing and supports a clean installation, while the included billet reservoir clamp secures the remote reservoir where applicable. Black bellows provide additional protection for the shock assembly in harsh environments.
The Bilstein B8 5160 is designed for direct fitment on the front suspension of select Chevrolet Colorado and GMC Canyon models. It uses 14.1mm eye-style upper and lower mounts and provides a 9.64-inch stroke between a 15.25-inch collapsed length and a 24.89-inch extended length. The shock is not a coilover and does not include a spring seat. Verify vehicle configuration and suspension lift requirements before ordering to ensure proper fitment.
