The Rock Krawler COMP 5.5 X Factor Long Arm System is the ultimate Long Arm Suspension System for Wrangler JK Owners. The steering geometry has been engineered to provide you with stock on highway handling characteristics. What makes this long arm system 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 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 control. There is no limit to what you can do with the COMP 55 X Factor 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 rear shock relocation brackets that move the rear shocks up 2" for better ground clearance. 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. The big bonus of this system is the inclusion of massive long travel coil over shocks up front! The RRD coil over assemblies feature a true dual rate coil assembly for improved off-road ability with massive off camber gains! The adjustability of height in the front end allows you to dial in the stance of your JK just as you want it. 2 door JK owners will be able to upgrade to a stretch version of this great system. The COMP 55 system comes with our exclusive Abuse Proof Lifetime Warranty on all hard parts!
