Rock Krawler JL/JLU Adventure X Arm Package
The Rock Krawler Adventure-X Control Arm Package is the definitive "bulletproof" upgrade for Jeep Wrangler JL and JLU owners looking to replace their thin, stamped-steel factory arms with high-strength, adjustable components. This complete set of eight arms (front and rear, upper and lower) is designed to handle the increased stress of larger tires and off-road abuse while providing the adjustability needed to fix "flighty" steering and driveline vibrations. Whether you are correcting a budget lift or building a high-performance crawler from scratch, these arms serve as the heavy-duty backbone of your suspension system.
Each arm is outfitted with Rock Krawler’s proprietary Pro Flex Joints, which are widely regarded as some of the most durable in the industry. These joints offer a staggering 70∘ of total misalignment, allowing your axles to articulate freely without the "binding" common in rubber or polyurethane bushings. Because they are 100% service-free and silent, you get all the performance benefits of a dedicated race joint without the constant need for greasing or the annoying "clunking" sounds that often plague aftermarket suspension builds.
Precision Geometry Correction: With all eight arms being fully adjustable, you can perfectly dial in your front caster for a stable, centered steering feel and rotate your rear pinion angle to eliminate vibrations—critical for both short-wheelbase 2-doors and heavy 4-door models.
Maintenance-Free "Pro Flex" Joints: These joints are 100% service-free, meaning they require no grease and no rebuilding. They are designed to be completely silent on the road while providing massive flex off-road.
Indestructible Construction: Built from heavy-duty, solid-steel or thick-walled tubing (depending on the specific arm), these are designed to slide over rocks rather than bend. They come with a lifetime "Abuse It" warranty—if you break it on the trail, they replace it.
Unrivaled Articulation: Offering 70∘ of misalignment, these arms allow your suspension to reach its full potential travel, keeping your tires in contact with the ground on technical obstacles where factory arms would bind.
High-Clearance Design: The lower arms are specifically shaped to provide maximum ground clearance. This "high-clearance" bend helps you avoid getting hung up on trail obstacles that would typically snag the straight factory control arms.
