The Rock Krawler Suspension LJ Wrangler 3.5 inch X-Factor X2 Flat-Belly Long-Arm System W/ 4 INCH STRETCH is a massive evolution to long arm systems for TJ and LJ Wranglers. NOW with an additional 4" of rear upper and lower control arm stretch. We led the way with the Revolutionary X-Factor Long Arm design featuring the industry's first Independent 3-Link Front and Triangulated 4-Link Rear Suspension Design Ever! The X-Factor Long Arm design has stood the test of time and has been mimicked by many other companies in its 20+ year history! How do we as an industry leader blow something out of the water that has done so well for so long? The answer is the all new TJ/LJ X Factor X2 Flat Belly Long Arm Systems. The industry’s only full flat belly long arm system where all the arms tuck up right inside the frame! The X-Factor X2 geometry is enhanced above and beyond our old X-Factor Long Arm, adding more double triangulation to the rear for even better stability. The ride quality has also improved by adding our Adventure Series Joints to the frame side of the lower control arms and thus reducing overall system maintenance. The newer Pro-X Krawler Joints with the one piece BASF thermo-elastomer material round out the joints used in the system for an unbelievable 95 degrees of misalignment or more, available on each and every control arm in the system. Of course, these systems come with our technologically advanced and tuned Triple Rate Coils Front and Rear. No one can beat this combination of cross over angles, ground clearance gains, ride quality, tuned suspension performance, durability and our abuse proof lifetime warranty on all hard parts. The Rock Krawler X-Factor X2 Flat Belly Long Arm System is paving the way for future TJ and LJ Builds.
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:
- Includes hardware and detailed instructions
- Designed for OEM axles and OEM axle control arm mounting widths (Dana 30/44).
- For use with axles that will not be able to achieve OEM lower control arm mounting widths please call as it will require customized lower control arm bend profiles similar to how we do Rockzilla Systems and Upgrades.
- Requires a SYE with C.V. Driveshaft With long rear uppers, a custom cat back exhaust is required
- Rubicon Edition TJ's require a new rear driveshaft
- 2003 TJ's equipped with 4 speed automatics will require removal of the factory automatic transmission skid plate if so equipped to allow for proper front driveshaft travel
- Requires removal of the OEM rear upper control arm mounts off the rear axle
- Recommend using rear shock relocation brackets or rear shock shifters for some applications
- Requires Artec or Motobilt HD Body Mounts that raise the body 1.25” and a small motor mount lift or 1.5” Body Lift/Motor Mount Lift or Greater.
- Remember to combine suspension lift height and body lift height or body mount replacement and your total lift height to achieve your desired overall all tire clearance.
