Rock Krawler 2020+ Jeep Wrangler JLU 4DR 4.5in X Factor X2 (No Limits) Long Arm Suspension

The Rock Krawler X Factor X2 Long Arm system for your 2020+ Jeep Wrangler JLU 4-door starts with 2-inch diameter, 1/4-inch wall DOM tubing for the long control arms. This robust construction is designed to handle the stresses of serious off-roading and provides a solid foundation for a 4.5-inch suspension lift. The X2 system is engineered to offer significant improvements in suspension articulation and on-road comfort, making it a comprehensive upgrade for your JLU.

This kit includes Rock Krawler's proprietary "No Limits" front and rear sway bar disconnects, allowing for maximum wheel travel when you're off the beaten path. The long arm geometry is carefully calculated to correct caster and pinion angles, which is crucial for maintaining proper driveline angles and improving handling characteristics after a lift. You'll also find adjustable rear track bar relocation brackets and a rear track bar, ensuring your axle stays centered under the vehicle. The system utilizes Rk's triple-rate coil springs, which are designed to provide a balanced ride, offering good support for the vehicle's weight while still allowing for excellent flex.

Installation of this long arm system involves replacing the factory control arms with the new, longer units, and requires modifications to the frame mounts. It's a substantial upgrade that transforms the suspension's capability. For the best results and to ensure proper alignment and driveline function, it's recommended to have this system installed by a qualified professional. This kit is designed to be a complete solution for those looking to significantly enhance their JLU's off-road performance and on-road manners.
