Features & Product Details

The Rock Krawler 4.5" X-Factor COILOVER Mid-Arm Diesel 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. This system proves its durability and off-road performance every time you hit the streets or trail! Rock Krawler's industry leading, X-Factor Series, adjustable upper and lower control arms, offer a total of 95 degrees of misalignment when paired with their Pro-X Krawler Joints and Adventure Series joints. The inherent bind in a factory JL control arm is greatly reduced. The maintenance free "Adventure Series" joints are found in your front and rear control arms at the frame connection, while the "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 provided track bar geometry corrections, both front and rear, let you perfectly center the axles so there is no compromise in on road handling.

 

The Comp System (Front Coilovers w/ Rear Coil Combination) is ideal for those that want the adjustability and performance of coilover 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 Rock Krawler's systems, amazingly tuned ride and handling is their number one priority! It is no different with the 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! 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).
  • XR Package does not require Rock Krawler's raised rear track bar bracket, the factory axle has a raised rear trackbar bracket, and for their systems that do not have a rear trackbar one must be added.
  • If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
  • If building an overland 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)
  • Requires removal of the OEM shock mount off the frame (*If coilover system is purchased)
  • Requires removal of the OEM shock and spring mount off the axle (*If coilover system is purchased)
  • Requires welding of the new coil over mount on the axle only (*If coilover system is purchased)
