Rock Krawler 2020+ Jeep Wrangler JLU 4DR (Diesel) 4.5in Adventure-X Long Arm Suspension

This is the Rock Krawler 4.5-inch Adventure-X Long Arm Suspension system for the 2020 and newer Jeep Wrangler JLU 4-door models equipped with the diesel engine. This comprehensive kit is designed to significantly improve your Jeep's off-road capability and on-road manners, offering a substantial lift and a more refined suspension geometry.

The Adventure-X system is built around Rock Krawler's proven long-arm design, which relocates the suspension mounting points to provide a more optimal angle for the control arms. This results in better articulation off-road, allowing your wheels to maintain contact with uneven terrain for improved traction, while also offering a more comfortable and stable ride on the highway. The kit includes heavy-duty, adjustable long control arms made from solid steel, featuring Rock Krawler's proprietary R-Flex Joints. These joints offer a wide range of motion and are designed for durability and ease of maintenance. The system also incorporates taller springs and Fox 2.0 shocks, tuned specifically for this application, to handle the increased travel and provide excellent damping performance.

Installation of a long-arm suspension system is a complex job that typically requires advanced mechanical skills and specialized tools. It involves removing and replacing many original suspension components, and precise alignment is crucial after installation to ensure proper handling and tire wear. This kit is designed to be a complete solution, but it's important to consult the manufacturer's detailed installation instructions and consider professional installation if you are not experienced with major suspension modifications. The result is a Jeep that is significantly more capable off-road while maintaining a comfortable and predictable feel for daily driving.
