Rock Krawler's JK 3.5" Off-Road Pro Long Arm System is a race inspired system designed to take abuse. As JK's get older in years, they are getting wheeled harder and harder. The Off-Road Pro Systems are designed to minimize wear points while taking that punishment! As few as possible OEM mounting points have been used with this system. All ends of the control arms feature our Pro Series Krawler Joints so there are no bushings to break down from punishment. The suspension geometry features our tried and true independent 3 link design front and rear. There are no natural binding points, so the suspension cycles perfectly smooth. No system on the market today is ready for racing or absolute punishment like our Off-Road Pro Long Arm System.

Shocks: For generic and bilstein shocks, please ensure that 2" bump stops are utilized. Front shocks should be 16" collapsed to 28" extended, and rear shocks should be 16" collapsed to 26" extended. Bilstein part numbers that we recommend are 24-186995 for front, and 24-146715 for rear. If you order the kit with shocks (standard or coilover), the kit comes with extended bump stops.
Coilover Upgrade: If you order the coilover upgrade (stage 1 or stage 2), the kit comes with (4) coil over mounts that must be welded on! Coil overs are front only, the rear is still a coil spring and shock.
General 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. - We typically recommend 4.5" of back spacing on rims for 35" tall tires. - We typically recommend 3.5" of back spacing on rims for 37"/38" tall tires. -Will ride firmer than a system with bushings in the control arms, but will also handle tighter. - 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.
