Important Notes

  • Welding of the Rear Cradle, Rear Third Link Mount, Front and Rear Long Arm Mounts is required.
  • Removal of the OEM lower control arm mounts front and rear is required.
  • Removal of the front upper control arm mount on the driver side is required.
  • 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.
  • Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up.
  • Recommended 4.5" of back spacing on rims for 33" and 35" tall tires. 3.5" of back spacing on rims for 37 - 40" tall tires
  • 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.

Description

Rock Krawler's 5.5" Stage 2 X-Factor Long Arm System Lift Kit provides improved off-road performance with excellent highway ride and handling. The rear axle is pushed back up to 1" over stock which perfectly centers the rear axle assembly under typical aftermarket flat fenders. This kit features front and rear 2.0" RRD Remote Reservoir Shocks and extended bump stops. It also allows for larger tires without contacting the rock sliders or rear pinch seam. This complete bolt in system is upgradeable to any other Rock Krawler system.
