The Rock Krawler Wrangler JK 3.5” X Factor Plus System is the ultimate Suspension System for JK owners looking to run up to a 35” tall tire! Each and every part of the factory suspension is either upgraded or replaced. The steering geometry has been engineered to provide you with stock on highway handling characteristics. What makes this system special is what it can do for you when the pavement ends! The 3.5” X Factor Plus System off-road has all the bells and whistles to assure you of a great adventure. You get high clearance - high misalignment lower control arms front and rear, high misalignment front upper adjustable control arms, front sway bar disconnects, and long travel stainless steel brake lines to name a few. What makes this system really awesome is the independent three link rear conversion with adjustable anti-squat geometry. This is a feature no other suspension systems can match! Even the small details have not been over looked. The rear axle on the 3.5” X Factor Plus System is moved back 1” to allow for greater clearance between the tire and the factory rock slider for all you JK owners with the factory Rubicon Package. There are rear shock relocation brackets that move the rear shock mounting position up 2 inches for better ground clearance under the lower control arm mounts on the axle. 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!
