Features & Product Details

The Rock Krawler Suspension 4.5" X - Factor X2 "No Limits" Long-Arm 392 System is specifically designed for Wrangler owners who want to push their vehicle to its limits with hard core rock crawling. The Term, "No-Limits" comes from the inclusion of the 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 Rock Krawler X2 Longarm System features an Independent 3 link design front & rear for maximum articulation and off-road performance. The proprietary design utilizes a double adjustable front and rear upper control arm that upsizes the factory hardware to 14mm, 2 3/8" mounting width and 1" Pro Krawler joints at each end. The arm itself is a chromoly solid steel arm meant to carry all the forces of the suspension. The rear suspension provides adjustable anti-squat with "X2" rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). As you drive the highways or the trails, the system feels stable, safe and strong whether you are running the stock drivetrain or pushing high horsepower through the chassis.

 

Rock Krawler built the X-Factor X2 system to be the toughest 3-Link setup on the market. At the frame connections of the lower control arms, the "Adventure Series" maintenance free joint is used to cut down on the amount of grease points and provide excellent vibration absorption and proper joint misalignment when off-road. The combination of high clearance long arms and 3 link suspension geometry let you dominate the trails. When Rock Krawler designs a system, their 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).
  • 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 upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
  • Recommend a new front C.V. driveshaft for all front shocks with max. extended length greater than 29"
  • Front 3-Link suspension systems require aftermarket front axles that don't have F.A.D.
  • Requires welding of the Front and Rear Long Arm Mounts
  • Requires removal of the OEM frame side lower front and rear control arm mounts
  • Requires removal of the OEM frame side front and rear upper control arm mounts
  • Requires removal of the OEM axle side rear lower control arm and track bar mounts
  • Requires modifying the OEM rear shock mounts and welding of the raised rear upper shock mounts
  • Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up
