The Rock Krawler Suspension TJ Wrangler 4.5 inch X-Factor X2 Flat-Belly COILOVER Long-Arm System is a massive evolution to long arm systems for TJ and LJ Wranglers. This incredible system allows you to add a full, weld-in Coilover system front suspension, and keep a traditional spring and shock rear setup. 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
