Rock Krawler JL35AX2NL-4S1 3.5 Inch Adventure-X2 No Limits Long Arm Suspension System Stage 1

The Rock Krawler JL35AX2NL-4S1 is a 3.5-inch Adventure-X2 "No Limits" Long Arm Suspension System (Stage 1) engineered to bridge the gap between capable daily driver and hardcore off-road rig. This comprehensive long arm lift system delivers a full high clearance 4-link front suspension paired with a high clearance independent 3-link rear suspension for a potent combination of street manners and trail domination.

The "No Limits" designation refers to the inclusion of specially engineered front sway bar links designed to work seamlessly with the factory electronic sway bar disconnect feature found on Rubicon Wranglers. These sway bar links feature factory-sized hardware, a CNC machined billet aluminum center section, and USA-made FK Bearing heim joints — simply press the button and hit the rocks.

The "Adventure-X2" name reflects the system's 8 fully adjustable control arms equipped with 100% service-free Adventure Series joints. These arms offer up to 70 degrees of misalignment at both the frame and axle connection points, significantly reducing the bind inherent in factory JL control arms and allowing precise tuning of caster and pinion angle front and rear.

Key Features:

• 3.5 inches of lift height (based on Rubicon models with standard build)
• Full high clearance 4-link long arm front suspension with high clearance independent 3-link rear suspension
• "No Limits" CNC machined billet aluminum sway bar links with FK Bearing USA-made heim joints — compatible with factory Rubicon electronic sway bar disconnect
• 8 fully adjustable control arms with 100% service-free Adventure Series joints (70 degrees of misalignment)
• Triple-rate coil springs — all 4 coils engineered for superior on-road comfort over OEM linear rate springs
• Coils built with proper free-length for off-road articulation, staying firmly seated in the coil bucket
• Correction pads included to reduce the spring bow inherent in the factory setup
• Front and rear track bar geometry corrections to perfectly center axles for no compromise in on-road handling
• RRD Spec'd 2.25-inch shocks: fluted aluminum construction, military-grade hard coat black anodizing, 7/8-inch shaft, IFP (Internal Floating Piston), fully serviceable and rebuildable
• Stage 1 package — complete system ready for installation

Rock Krawler's long arm geometry provides improved suspension kinematics over mid-arm designs, delivering better flex, reduced bind, and more controlled articulation on the trail. The system is designed as a comprehensive, bolt-in solution for Jeep Wrangler JL owners seeking the best balance of on-road comfort and off-road performance.
