Construction & Design

The Bilstein B8 5100 shocks feature a robust monotube construction that outperforms traditional twin-tube shocks by providing better heat dissipation and more consistent damping. This design includes a larger piston surface area, allowing for precise control over suspension movement and improved responsiveness.

High-quality internal components resist wear and corrosion, ensuring durability even under demanding off-road conditions. The velocity sensitive, digressive piston technology intelligently adjusts damping force based on suspension travel speed, delivering a smooth ride during normal driving and firm control during aggressive maneuvers or rough terrain.

Installation & Fitment

Installation of the Bilstein B8 5100 Rear Shocks is straightforward for Jeep Wrangler TJ owners with a 3.5 to 4-inch rear lift and short arm lift kit. These shocks are designed as direct replacements for the factory rear shocks and require no additional modifications or special tools. For optimal suspension balance and performance, it is recommended to replace both rear shocks simultaneously.

While experienced enthusiasts can perform the installation with basic hand tools and a vehicle lift or jack stands, professional installation is advised for those unfamiliar with suspension work. Proper torque specifications and alignment checks should be followed to ensure safety and peak performance.
