Rock Krawler JL35AXPNL-392 3.5 Inch Adventure-X No Limits Long Arm Suspension System

The Rock Krawler JL35AXPNL-392 is a 3.5-inch Adventure-X "No Limits" Long Arm Suspension System engineered specifically for the Wrangler 392 platform. Designed to strike the ideal balance between daily driver comfort and hard-core off-road performance, this comprehensive long arm system delivers superior geometry, articulation, and ride quality for Rubicon 392 owners demanding the best from both worlds.

The "Adventure-X" designation reflects the inclusion of 8 fully adjustable control arms equipped with 100% service-free Adventure Series joints — eliminating the need for routine greasing while providing long-term durability and peace of mind on and off the trail.

The "No Limits" name comes from purpose-built front sway bar links designed to work seamlessly with the factory electronic sway bar disconnect system found on Rubicon models. These links feature factory-sized hardware, a CNC machined billet aluminum center section, and American-made FK Bearing heim joints — simply press the button and hit the rocks.

392-specific Triple Rate Coil Springs are included to account for the additional weight of the 6.4L V8 engine, delivering 3.5 inches of lift over the factory 1-inch Rubicon ride height. All four coils are tuned for excellent on-road comfort while maintaining proper free-length for maximum off-road articulation.

Key Features:

• 3.5-inch lift height — tuned specifically for the 392 platform over factory ride height
• Full high clearance 4-link long arm front suspension paired with a high clearance independent 3-link long arm rear suspension
• 8 fully adjustable control arms with 100% service-free Adventure Series joints
• 392-specific Triple Rate Coil Springs engineered for the heavier V8 drivetrain
• "No Limits" CNC machined billet aluminum front sway bar links with FK Bearing USA-made heim joints
• X2 rear axle bracket system provides 4.5 inches of additional ground clearance under the rear axle
• Rear upper shock relocation brackets to preserve full shock and suspension travel
• Correction pads included to reduce factory spring bow
• Front and rear track bar geometry corrections for proper axle centering
• Compatible with 37"–40" tall tires depending on fender configuration

Installation requires welding of front and rear long arm mounts and removal of OEM frame-side control arm mounts. Limiting straps are recommended after final setup to protect suspension components from over-extension. This system is the foundation for every adventure — from daily commutes to the most demanding trails in America.
