Rock Krawler Suspension JL45AXMNL-4XES1 4.5 Inch Adventure-X No Limits Mid-Arm Lift Kit Stage 1

The Rock Krawler Suspension JL 4.5 inch Adventure-X "No-Limits" Mid-Arm System is specifically designed for Rubicon owners who want a complete system, bolt-in installation, and the best articulation of any mid-arm kit on the market. This Stage 1 system delivers proven durability and off-road performance while maintaining excellent on-road comfort.

No-Limits Sway Bar Technology:

The "No-Limits" designation comes from the inclusion of front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in Rubicon Wranglers. The sway bar links feature factory-sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing.

Adventure-X Control Arm System:

The Adventure-X name refers to the inclusion of 8 adjustable control arms with 100% service-free Adventure Series joints installed. The industry-leading Adventure-X mid-arms feature adjustable upper and lower control arms offering a total of 70 degrees of misalignment when paired with Adventure series joints at the frame connection and axle. This adjustability allows you to precision tune the JL's caster and pinion angle front and rear.

Triple-Rate Coil Technology:

The system includes triple-rate coils that deliver the most comfortable ride possible in a Wrangler. All 4 coils work together to achieve excellent on-road comfort that outperforms OEM linear rate springs. The coils are built with proper "free-length" for off-road articulation and stay firmly seated in the coil bucket, providing controlled reaction to bumps, rocks, sand, and mud.

Complete Geometry Correction:

All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory setup. The system includes front and rear track bar geometry corrections to perfectly center the axles without compromising on-road handling.
