Rock Krawler JL45X2PNL-4DCS 4.5 Inch X Factor X2 Pro No Limits Long Arm Coil Over Suspension Kit

Rock Krawler's JL45X2PNL-4DCS is a 4.5-inch X Factor X2 Pro No Limits Long Arm Coil Over Suspension System engineered for serious rock crawling performance on the Jeep Wrangler JL 4-Door. This system combines long-arm geometry with a front coil over setup and the exclusive "No Limits" sway bar link package, making it purpose-built for Rubicon owners who demand maximum articulation without sacrificing factory convenience.

The "No Limits" designation reflects the inclusion of specially engineered front sway bar links that are fully compatible with the factory Rubicon electronic sway bar disconnect system, allowing full articulation at the press of a button without removing any hardware.

Key Features:

• 4.5-inch lift with front coil over configuration for maximum suspension travel
• Independent 3-link design front and rear for superior articulation and off-road performance
• X2 rear suspension geometry with adjustable anti-squat, enhanced rear instant center(s), and improved rear roll center(s)
• High clearance X2 axle bracket system delivers 4.5 inches of additional ground clearance under the rear axle versus stock
• Rear upper shock relocation brackets preserve full shock and suspension travel
• No Limits front sway bar links engineered for use with the factory Rubicon electronic sway bar disconnect
• Double adjustable front and rear upper control arms with upsized 14mm hardware, 2-3/8" mounting width, and 1" Pro Krawler joints at each end
• Adventure Series maintenance-free joints at frame connection points; Pro Krawler Joints at axle connections
• 95 degrees of total misalignment when X-Factor arms are paired with Pro-X Krawler Joints and Adventure Series joints
• Triple-rate coil springs for superior on-road comfort and off-road articulation
• OEM-style heat shield thermal barrier protecting front control arm joints at the frame
• Geometry correction pads included to reduce factory spring bow
• Front and rear track bar geometry corrections for precise axle centering and on-road handling

Installation Notes: This system requires welding of front and rear long arm mounts, removal of OEM frame-side lower and upper control arm mounts (front and rear), removal of OEM axle-side rear lower control arm and track bar mounts, and modification of OEM rear shock mounts. A front aftermarket axle housing with FAD delete is required for welding the front upper arm mount. An aftermarket front CV driveshaft is recommended for front shocks with a maximum extended length greater than 29 inches. Installation of limiting straps is recommended after final setup to prevent over-extension of suspension components.

The Rock Krawler X Factor X2 Pro No Limits system represents the pinnacle of JL long-arm suspension engineering — delivering the geometry, hardware quality, and articulation needed to confidently tackle the most demanding rock crawling terrain.
