Rock Krawler JLAXPLA-UPG Adventure-X PRO Long-Arm Suspension Upgrade

The Rock Krawler JLAXPLA-UPG Adventure-X PRO Long-Arm Upgrade is a comprehensive long-arm suspension conversion designed to transform the Jeep Wrangler JL/JLU into a capable platform that excels both on the street and on the trail. This upgrade system combines a fully high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension for optimized geometry, articulation, and ground clearance.

The "PRO" designation means this kit is equipped with four billet aluminum CNC-machined, service-free lower control arms in long-arm length — delivering maximum strength with zero maintenance. Each control arm features Rock Krawler's Adventure Series joint center, which isolates harsh road vibrations compared to OEM bushings. The high-misalignment joint uses a steel sleeve rotating freely on a Teflon-lined inner sleeve, eliminating bushing deformation through mud, sand, snow, salt, and dirt.

• Full high-clearance 4-link long-arm front suspension conversion
• High-clearance independent 3-link rear suspension
