    2.5" X Factor Long Arm System for JK 4 Door 

    The Rock Krawler 2.5" X Factor Long Arm System is the best performing trail suspension for Jeep Wrangler JK 4 Door owners looking to run 35" tires with stock fenders or 37" tires with flat fenders. This system features the RK Independent 3 Link Conversion front and rear, with a 100% bind free design that has proven itself 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 crossover angles and ground clearance. The rear suspension features adjustable anti-squat so you can dial in your JKs suspension to your liking. All of the high clearance lower control arms are made from custom 2" OD 7/16 wall DOM steel and built for abuse. Like all other JK X-Factor systems, the rear axle has been moved back 1" to allow for greater clearance between the tire and factory sliders for Rubicon owners. This system is completely upgradeable to any other RK Wrangler JK system and comes with their exclusive Abuse Proof Lifetime Warranty on all hard parts.

    ** Welding of the rear cradle, rear third link mount, front and rear long arm mounts is required
    *** Removable of the OEM lower control arm mounts front and rear is required
    **** Removable of the front upper control arm mount on the driver side is required
    ***** Minor exhaust rerouting required before the collector on the drivers side. This is recommended to be done prior to the suspension system being installed.
    ****** Recommend installing limiting straps to avoid over extension of the suspension components after vehicle is set up
    ******* Recommended 4.5" of backspacing on rims for 33"-35" tall tires. 3.5" of backspacing on rims for 37" tall tires
    ******** Allows the rear axle to be pushed back up to 1" over stock, which perfectly centers the rear axle assembly under typical aftermarket flat fenders. It also allows for larger tires without contacting the rock sliders or rear pinch seam.
    ********* The rear upper third link is designed around standard low pinion rear axles. Before ordering for high pinion rear axles, please contact us directly so we can ensure proper fitment.
