The Rock Krawler Wrangler JK 3.5” X Factor Long Arm Stretch System is a great long arm system for 2 door owners looking to gain a little wheel base to improve off-road ability, while still maintaining it perfectly street legal! Not only will the increase in wheel base improve off-road ability, but it will also improve over all ride quality. 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 Wrangler JK X Factor Long Arm Stretch 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 double 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 and front spring retainer clips so your front coils springs do not fall out under high articulation. The rear axle has been moved back 3” to provide a perfect 99" wheel base. This system is completely upgradeable to coil overs and comes with our exclusive Abuse Proof Lifetime Warranty on all hard parts!
