Rock Krawler 4.5" X-Factor PRO Elite COILOVER "No Limits" Mid-Arm System for Jeep Wrangler JL (Gas Models)
The Rock Krawler 4.5" X-Factor PRO ELITE COILOVER "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. The lower control arms are our signature PB+J (Pure Beef and Jealousy) mid-arms machined from 2” x 3” billet 7075 Aluminum. All 4 other control arms are machined from round 7075 Aluminum and come with the benefits of X-Factor built right in. 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. The “No Limits” front sway bar end links pair amazingly well with the factory Rubicon E Disconnect ensuring bind free suspension travel in the roughest of terrains.
The Comp System (Front Coilovers w/ Rear Coil Combination) is ideal for those that want the adjustability and performance of coil over racing shocks up front, but still want to use their Wrangler to carry small loads or tow small trailers. There are two options for the Comp Systems you can choose from. The standard or Stage 1 System features 2 5/8" RRD Racing Coilovers w/ Remote Reservoirs up front paired with matching 2 5/8" RRD Racing Shocks w/ Remote Reservoirs in the rear for a well tuned package. Or you can opt for the Stage 2 Comp System which will include Fast CD (Compression Dampening) Adjusters on the coilovers and rear shocks for an even greater level of tuneability.
Like all of our systems, amazingly tuned ride and handling is our number one priority! It is no different with our coilover systems. Coilovers add another level of tuneability for the vehicle owner to further enhance the ride, handling and off road performance to their liking. Install exceptional value, and be the foundation for every adventure whether it be on the Street or on the Trail with a Rock Krawler Coilover Suspension System!

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.
Requires removal of the OEM shock mount of frame
Requires removal of the OEM shock and spring mount of the axle
Requires welding of the new coilover mount on the axle only
