Construction & Design

The Bilstein B8 5100 Rear Shock features a rugged monotube construction that enhances heat dissipation, preventing shock fade during extended use. Its smooth body design not only improves durability but also simplifies installation. The zinc plating safeguards the shock absorber against corrosion and environmental wear, extending its service life even in harsh conditions.

Inside, a velocity sensitive piston with a digressive damping curve allows the shock to respond precisely to changes in terrain and driving style. This results in a suspension that is both comfortable on smooth roads and controlled over rough off-road surfaces. Each shock is meticulously tuned to complement the Jeep Gladiator’s suspension geometry and accommodate the specified rear lift height, ensuring stable and predictable handling.
