The Rock Krawler JK 3.5 X Factor X2 Stretch Systems is the ultimate JK Long Arm system for the trail. The X Factor systems feature 3 link rear set-up front & rear for maximum articulation and off-road performance. The rear suspension provides the tried and true independent 3 link conversion with X2 rear suspension geometry. New high clearance axle mounts provide 3.5” of ground clearance under the rear axle as compared to stock. Rear upper shock relocation brackets ensure you do not lose any shock travel. The combination of high clearance mounts and 3 link suspension geometry lets you dominate the trails.

Notes
*The X Factor Stretch System is designed for flat fender and stretch rear corner use. This will require body work.
*Requires removal of the OEM frame side front and rear lower control arm mounts.
*Requires removal of the OEM frame side front and rear upper control arm mounts.
*Requires welding of the front and rear frame side long arm mounts.
*Minor exhaust rerouting required before the collector on the driver's side. This is recommended to be done prior to the suspension system being installed.
*Requires removal of the OEM rear axle side brackets.
*Requires welding of the provided rear axle side control arm/shock/sway bar link bracket, track bar bracket and rear axle truss.
*Requires removal of the OEM frame side rear shock mount.
*Requires welding of the provided frame side rear shock mount and rear third link mount.
*Rear shocks will require a standard bushing and sleeve just like the rear lower shock bushing and sleeve. We have removed the weakness of the bar pin setup with the supplied rear upper shock mounts.
*Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up.
*We typically recommend 4.5” of back spacing on rims for 33” and 35” tall tires.
*We typically recommend 3.5” of back spacing on rims for 37” tall tires.
*The X Factor System 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. When ordering for high pinion rear axles please contact us directly so we can ensure proper fitment as best as possible.
