Rock Krawler X Factor X2 PRO ELITE w/ 6" Stretch Long-Arm Upgrade For Jeep JK/JKU

The Rock Krawler Suspension 4.5" X - Factor X2 6" Stretch PRO ELITE Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. PRO derives from having a set of PB&J (Pure beef and jealousy) Billet aluminum lower control arms. These arms are custom machined in-house, built using a solid square stock bar of BILLET aluminum and engineered to quite literally, handle any abuse you can throw at them. The X - Factor X2 systems combine the benefits of a independent 3 link front and rear suspension system. This is where conventional on road handling meets bad ass off-road ability. Our proprietary design utilizes a double adjustable front and rear upper control arm that upsizes the factory hardware to 14mm, 2 3/8" mounting width and 1" Pro Krawler joints at one end. The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). We provide the necessary brackets and control arms needed to achieve a 6" rear suspension stretch in order to give an enhanced wheelbase. This helps with greater off-road capability and better on-road handling characteristics in a 2-door wrangler. The new high clearance axle mounts provide 3.5” of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel.

General Notes:

All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare).
If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
If building an overland or heavily up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
We recommend a new front driveshaft if you plan to off-road routinely. (Adam's Driveshaft Woods, J.E. Reel, etc.)
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 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.
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.
Requires modifying the OEM front & rear shock mounts and welding of the raised upper shock mounts.
