General Notes:

• May require purchase of JK Rear Stretch Frame-Side Track Bar - RK03155 to complete proper alignment with stretch.
• 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 welding of the rear third link mount. Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up. We typically recommend 4.5 inch of back spacing on rims for 33 inch and 35 inch tall tires. We typically recommend 3.5 inch of back spacing on rims for 37 inch 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.
