Rock Krawler 07-18 Jeep Wrangler JK 4DR 4.5in X Factor X2 Pro Long Arm

Built with 2-inch diameter, 5/16-inch wall DOM tubing, the Rock Krawler X Factor X2 Pro Long Arm system is a serious upgrade for your 2007-2018 Jeep Wrangler JK 4-door. This isn't just about adding lift; it's about fundamentally changing how your Jeep handles off-road and on pavement, especially when you're running 4.5 inches of suspension travel. The long arm geometry is designed to improve articulation, allowing your wheels to maintain better contact with the terrain over obstacles, while also providing a more stable and predictable ride on the road. This system is engineered to handle the demands of aggressive off-roading, offering a significant improvement in both capability and comfort.

The X2 Pro system incorporates Rock Krawler's advanced long arm mounting system, which relocates the control arm mounting points on the frame. This geometry correction is crucial for maintaining proper caster and pinion angles, especially with the increased suspension travel. The kit includes front and rear long control arms, fabricated mid-arm brackets, and all necessary hardware for installation. The heavy-duty construction, using thick-wall DOM tubing, ensures durability and resistance to bending or damage in harsh environments. This system is a comprehensive solution for JK owners looking to maximize their off-road performance and on-road manners.

When installing a long arm kit like this, it's important to understand that it requires significant modifications to the frame and suspension mounting points. Refer to the manufacturer's detailed installation instructions for the complete procedure, including any specific tool requirements or torque specifications. This system is designed to work with 4.5 inches of lift and is a foundational component for building a highly capable Jeep Wrangler JK.
