MIA's Description

The Rock Krawler Suspension JL 4.5 inch Adventure - X 392 "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. Our system proves its durability and off-road performance every time you hits the streets or trail! The Term, "No-Limits" comes from the inclusion of our front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Wrangler! The sway bar links themselves come with factory sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing, once installed, just press the button and hit the rocks! The Term, Adventure - X comes from the inclusion of 8 adjustable control arms with our 100% Service Free Adventure Series joints installed. Rock Krawler's industry leading, Adventure - X mid-Arms feature adjustable upper and lower control arms and offer a total of 70 degrees of misalignment when paired with our Adventure series Joints at the frame connection and at the axle. The inherent bind in a factory JL control arm is greatly reduced. With so much adjustability, it allows you to precision tune the JL's caster and pinion angle front and rear. Driving you home with the most comfortable ride possible in a Wrangler, are our TRIPLE RATE coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the 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 (as long as a proper length shock is installed), and overall a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on road handling.
