Rock Krawler 2018+ Jeep Wrangler JL 2DR / JLU 4DR Box Kit JL X2NL-COMP

If you're looking to significantly upgrade your 2018 and newer Jeep Wrangler JL's suspension for serious off-road performance, the Rock Krawler JL X2NL-COMP Box Kit is a comprehensive solution. This kit is designed to provide the framework for a robust suspension system, allowing your Jeep to handle challenging terrain with improved articulation and stability. It's built for those who push their Jeeps beyond the pavement and demand reliable performance when the trail gets tough.

This kit centers around Rock Krawler's X-Factor 2.5" long arm suspension system, known for its ability to provide excellent ground clearance and articulation. The components are constructed from solid steel, with the control arms featuring a 1.75" x 0.250" wall thickness for exceptional strength. The system utilizes Rock Krawler's proprietary RRD (Race Ready Design) shocks, which are tuned to complement the long arm geometry, offering a comfortable ride on-road while maintaining control off-road. The kit includes all the necessary brackets and hardware to integrate the long arm setup, fundamentally changing how your suspension performs and allowing for larger tire fitment without excessive modification.

When installing a long arm kit like this, it's important to understand that it involves modifying the Jeep's frame to mount the new, longer control arms. This typically requires welding and precise alignment to ensure optimal performance and safety. While this kit provides the core components for a major suspension overhaul, you'll want to consult the manufacturer's detailed installation instructions for specific requirements and recommended procedures. This kit is a foundational piece for building a highly capable off-road machine.
