Rock Krawler 07-18 Jeep Wrangler JK/JKU 4.5 AX/X2 Long Arm Kit Box

Built with 1.75-inch diameter, 0.25-inch wall thickness DOM tubing, this Rock Krawler long arm kit box is designed to significantly improve the suspension performance of your 2007-2018 Jeep Wrangler JK or JKU. This kit is specifically engineered to work with Rock Krawler's AX/X2 suspension systems, providing a robust foundation for enhanced articulation and on-road comfort. By replacing the factory control arms with longer, stronger units, this system allows for better axle positioning and geometry correction, especially when lifting your Jeep significantly. The long arm design inherently offers improved suspension travel and a smoother ride compared to short arm setups. This is because the longer arms create a more favorable suspension arc, reducing binding and stress on the components. The DOM tubing used is known for its strength and durability, able to withstand the rigors of off-road use while maintaining its structural integrity. This kit box contains the essential long arm components needed to upgrade your JK/JKU's suspension, setting the stage for a more capable and comfortable driving experience, whether you're crawling rocks or cruising down the highway. When installing a long arm kit like this, it's important to note that it often requires modifications to the frame and may necessitate adjustments to driveline angles, especially with taller lifts. This kit is a core part of a comprehensive suspension upgrade, and you'll want to ensure all other supporting components are in good condition and compatible. Refer to the manufacturer's installation instructions for detailed guidance on proper fitment and setup to achieve the best possible performance from your Rock Krawler suspension.
