X Factor Plus Long Arm Upgrade

  • Model: X Factor Plus Long Arm Upgrade


The Rock Krawler Wrangler JK X Factor Plus Long Arm Upgrade is the ultimate Long Arm Upgrade System for JK Owners who want the ultimate trail machine while improving the overall ride quality and handling of their existing suspension system! What makes this long arm upgrade stand out above all the rest is the Revolutionary Independent Three Link conversion front and rear. This has become a Rock Krawler Suspension trade mark. All of our Jeep X Factor Plus Long Arm systems feature this very same design up front. On the new Wrangler JK’s we used it in the rear as well so no gas tank modifications would be required. The Independent Three Link has been proven as the best suspension design for high articulation demands while maintaining precise street handling. There is no limit to what you can do with the Wrangler JK X Factor Plus Long Arm System. No detail has been overlooked. The rear features adjustable anti-squat so you can tune your JK for your off-road pleasure. All the lower control arms are adjustable, have high clearance and are made from 2” solid alloy steel for extreme use. We provide you with even the little things such as a build a ball joint for your front differential mount. Like all other X Factor and X Factor Plus systems for the Wrangler JK, the rear axle has been moved back 1” to allow for greater clearance between the tire and factory sliders for Rubicon Owners. This system is completely upgradeable to any other Rock Krawler Wrangler JK System and comes with our exclusive Abuse Proof Lifetime Warranty on all hard parts!
