The Rock Krawler JK 3.5 inch X-Factor Long Arm System is the best performing trail suspension for JK owners looking to run 35 inch tall tires with stock fenders or up to 38 inch tall tires with flat fenders. This system features the Rock Krawler Independent Three Link Conversion. The Independent Three Link’s 100 percent bind free design has proven its self to be the best choice for those looking for maximum articulation while maintaining a factory like highway ride and tight handling.
This system features the best in class cross over angles and ground clearance.
The rear suspension features adjustable anti-squat so you can dial in your JK’s suspension to your liking. All of the high clearance lower control arms are made from 2 inch O.D. 7/16 Wall DOM steel and built for abuse. Like all other JK X-Factor Systems the rear axle has been moved back 1 inch to allow for greater clearance between the tire and factory sliders for Rubicon Owners.
