Rock Krawler 3.5" X Factor X2 Long-Arm System for 07-18 Jeep Wrangler JK
Superior Geometry and Ride Quality: By lengthening the control arms, the system minimizes the "swing arc" of the axle. This keeps your wheelbase consistent during compression and extension, resulting in a smoother ride that feels more like a luxury SUV than a lifted truck.
Abuse-Proof Durability: Rock Krawler is famous for its "Abuse Proof" lifetime warranty on all bent alloy steel components. The arms are constructed from heavy-wall tubing designed to slide over rocks rather than dent or fail under pressure.
Maintenance-Free Adventure Pro Joints: The X2 system features the latest Adventure Series joints, which provide massive amounts of misalignment (flex) while remaining quiet and vibration-free. They are greaseable and rebuildable, ensuring long-term performance without the "clunking" common in lesser kits.
Complete Correction: This isn't just a spring-and-shock lift. The kit includes high-clearance adjustable track bars and corrected sway bar links, ensuring your axles stay perfectly centered and your handling remains crisp and predictable.
Unrivaled Off-Road Flex: The long-arm configuration allows for significantly more wheel travel than short-arm kits. This keeps your tires in contact with the ground longer in deep ruts, providing the traction needed to conquer obstacles that stop other Jeeps in their tracks.
Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
Upgrading your Jeep Wrangler JK with the Rock Krawler 3.5" X Factor X2 Long-Arm System is the definitive move for enthusiasts who refuse to compromise between highway civility and extreme trail capability. Designed to bridge the gap between a daily driver and a dedicated rock crawler, this system replaces short, restrictive factory control arms with heavy-duty, long-travel geometry. By flattening the control arm angles, the X2 system significantly reduces "bump steer" and harsh feedback through the chassis, delivering a plush, controlled ride even over high-speed washboards or jagged technical terrain.
The engineering behind this kit focuses on maximum articulation and durability. Built from high-quality, solid steel, the components are designed to withstand the brutal vertical loads and lateral stresses of 37-inch tires. Whether you’re navigating the Rubicon Trail or cruising at 70 mph on the interstate, the Rock Krawler X Factor X2 ensures your suspension geometry remains optimized, keeping your tires planted and your center of gravity predictable.
