Rock Krawler 4.5" X-Factor COILOVER "No Limits" Mid-Arm Suspension System for Jeep Wrangler JLU (Gas Models)

Rock Krawler 4.5" X-Factor COILOVER "No Limits" Mid-Arm Suspension System for Jeep Wrangler JLU (Gas Models)

The Rock Krawler 4.5" X-Factor COILOVER Mid-Arm System is specifically designed for Sport and Sahara owners who want a complete system, bolt-in installation, and the best articulation of any MID-ARM kit on the market. 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! Our system proves its durability and off-road performance every time you hit the streets or trail! Our industry leading, X-Factor Series, adjustable upper and lower control arms offer a total of 95 degrees of misalignment when paired with our Pro-X Krawler Joints and Adventure Series joints. The inherent bind in a factory JL control arm is greatly reduced. Our maintenance free "Adventure Series" joints are found in your front and rear control arms at the frame connection, while our "PRO Krawler Joints" tie in your axle connections. 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 has 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. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail! Thank you for considering Rock Krawler Suspension.

General Notes:

All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare).
If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
If building an "overland style" or heavily up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
We recommend a new front driveshaft if you plan to off-road routinely. (Adam's Driveshaft, Tom Woods, J.E. Reel)
We recommend welding the rear cradle for use with 37" tires and above.
