Rock Krawler Suspension JL45AXMNL-4XECS 4.5 Inch Adventure X No Limits Mid-Arm Coil Over Suspension System

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 comprehensive coil over system delivers exceptional off-road performance while maintaining excellent on-road comfort and handling characteristics.

No-Limits Sway Bar Compatibility:

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 Arms:

The Adventure-X designation comes from the inclusion of 8 adjustable control arms with 100% service-free Adventure Series joints installed. These industry-leading mid-arms feature adjustable upper and lower control arms and offer 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 Springs:

Driving you home with the most comfortable ride possible are the triple-rate coils. All four coils work together to achieve excellent on-road comfort that exceeds OEM linear rate springs. The coil itself is built with the proper "free-length" for off-road articulation and stays firmly seated in the coil bucket, providing a very controlled reaction to bumps, rocks, sand, mud and whatever else you encounter.

Geometry Corrections:

All Rock Krawler JL systems include correction pads that reduce spring bow inherent in the factory setup. The provided track bar geometry corrections, both front and rear, perfectly center the axles so there is no compromise in on-road handling.

Installation Notes:

This coil over system requires removal of the OEM shock mount off the frame and removal of the OEM shock and spring mount off the axle. Welding of the new coil over mount on the axle is required. A new front driveshaft is recommended if you plan to off-road routinely.
