The Rock Krawler Suspension JK Wrangler 4.5 inch X - Factor X2 PRO 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 full high clearance independent 3 link front suspension with a high clearance independent 3 link rear suspension. 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 each end. The arm itself is a chromoly solid steel arm meant to carry all the forces of the suspension. 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). 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. The combination of a full high clearance independent 3 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.
When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail! Thank you for considering Rock Krawler Suspension

We typically recommend 3.5" of backspacing on a wheel used with 37" tall tires
Tire Fitment:
33" or 35" Tires using OEM fender flares
37" tires if using flat fenders
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 Drivesahft,Tom Woods,J.E. Reel)
