Construction & Design

Bilstein’s B8 5100 shocks feature a rugged monotube construction that excels in dissipating heat generated during demanding driving conditions, preventing fade and maintaining consistent performance. The smooth body design is crafted from high-strength materials and finished with a protective zinc plating to resist corrosion and wear over time. The internal velocity-sensitive piston technology intelligently adjusts damping force based on suspension movement speed, providing a balanced ride that is both comfortable and controlled.

Each shock is precisely engineered and tuned for the lifted Jeep Gladiator’s rear suspension geometry, ensuring compatibility and maximizing the benefits of your lift kit without sacrificing reliability or ride quality.

Installation & Fitment

The Bilstein B8 5100 Rear Shock is designed as a direct replacement for the rear shocks on 2020 to 2025 Jeep Gladiators equipped with a 3 to 4.5-inch rear lift. Installation is straightforward, requiring no special tools or modifications. Simply remove the factory shocks and bolt on the Bilstein units using existing mounting points. For optimal performance and safety, it is recommended to replace shocks in pairs, so a quantity of two is required for both rear sides.
