Are you JK owners looking to run up to a 35" tires with stock fenders or 37" tires with flat fenders? The Rock Krawler 2.5" X Factor Long Arm System Lift Kit is the best performing trail suspension kit. There is no limit to what you can do with the X Factor Long Arm System. The Independent Three Link has been proven as the best suspension design for high articulation demands while maintaining precise street control.. 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. The rear features adjustable anti-squat so you can tune your JK for your off-road pleasure. All the lower control arms are double adjustable, have high clearance and are made from 2" solid alloy steel for extreme use. On the new JK's we used it in the rear as well so no gas tank modifications would be required. 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 and front spring retainer clips so your front coils springs do not fall out under high articulation. Like all other X Factor Mid Arm or Long Arm 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.
