Rock Krawler JL45AXPNL-4S1 4.5 Inch Adventure-X PRO No Limits Long Arm Suspension System Stage 1

The Rock Krawler JL45AXPNL-4S1 is the 4.5-inch Adventure-X PRO "No Limits" Long Arm Suspension System Stage 1, engineered to deliver the ideal balance between daily street driving comfort and serious off-road performance. This comprehensive long arm lift system provides 4.5 inches of lift while dramatically improving suspension geometry, articulation, and overall capability over the factory setup.

The "PRO" designation means this system is equipped with four billet aluminum CNC machined, service-free lower control arms in a long arm configuration — delivering maximum strength with zero maintenance requirements. The Adventure-X name reflects the inclusion of eight fully adjustable control arms featuring Rock Krawler's 100% service-free Adventure Series joints, offering up to 70 degrees of misalignment to reduce factory bind and allow precise tuning of caster and pinion angle both front and rear.

The "No Limits" designation comes from specially engineered front sway bar links designed to integrate with the factory electronic sway bar disconnect found on Rubicon models. These links feature factory-sized hardware, a CNC machined billet aluminum center section, and USA-made FK Bearing heim joints.

Key Features:

• 4.5 inches of lift height for clearance of up to 42-inch tires (model dependent)
• Long arm configuration for improved suspension geometry and articulation
• 4 billet aluminum CNC machined, service-free PRO lower control arms
• 8 fully adjustable Adventure-X control arms with service-free joints
• "No Limits" front sway bar links compatible with factory Rubicon electronic sway bar disconnect
• CNC machined billet aluminum sway bar link center sections with USA-made FK Bearing heim joints
• Industry-leading triple-rate coil springs for superior on-road comfort over OEM linear-rate springs
• Track bar geometry correction included front and rear for proper axle centering
• Correction pads to reduce factory spring bow
• Stage 1 package includes shocks for a complete, ready-to-install suspension solution

Rock Krawler's triple-rate coils work in unison to deliver a controlled, comfortable ride on pavement while maintaining the proper free-length needed for maximum off-road articulation. All geometry corrections are included to perfectly center the axles and eliminate on-road compromise.
