B8 5100 Monotube Shock Absorber

The Bilstein B8 5100 shock absorber is engineered as a direct-fit solution for lifted trucks and SUVs, providing a significant improvement in ride quality, handling, and comfort. Its monotube design ensures consistent, fade-free performance, while the 46mm digressive piston with self-adjusting deflective disc valving reacts effectively to changing road conditions. This shock absorber is tuned for each specific application to achieve optimal performance, offering enhanced damping capabilities suitable for heavy hauling, towing, and off-road terrain. The zinc-plated finish provides durability and corrosion resistance, making it long-lasting even in harsh environments. The B8 5100 series is designed to be more compliant over bumps and holes compared to the Bilstein 4600 series, making it ideal for daily driven vehicles that also venture off-road. Specifications include an extended length of 18.98 inches, a collapsed length of 12.17 inches, and a travel length of 6.81 inches. It features an eye 16mm lower mount and a stem upper mount, with a smooth body design and no reservoir. The shock comes with a blue straight boot and is backed by a Limited Lifetime Warranty from Bilstein. This shock absorber is compatible with a wide range of Ford vehicles, including various models of the Bronco, Excursion, F-150, F-250, F-350, and Ranger from the 1980s through 2016, for the rear position. For factory-spec vehicles, Bilstein recommends the 4600 series shocks as their valving is more appropriate for daily driving and pavement environments.
