Rock Krawler 4.50-Inch X-Factor X2 PRO ELITE Stage 2 Long-Arm Suspension Lift Kit with Coil-Overs (07-18 Jeep Wrangler JK 4-Door)

The Rock Krawler Suspension 4.5" X - Factor X2 PRO ELITE COILOVER Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. The X - Factor systems combine the benefits of a full high clearance independent 3 link front suspension with a high clearance independent 3 link rear suspension. The "PRO ELITE" signifies you are entering the realm of PB&J (PURE BEEF AND JEALOUSY) by purchasing a system that is outfitted with 4 BILLET ALUMINUM CNC MACHINED lower control arms in a long-arm length! This is where conventional on road handling meets bad ass off-road ability. Up Front we have our proven 3 - link geometry with larger than factory hardware, a double adjustable front upper arm and wider than factory mounting width at the axle. This makes for an incredibly strong setup that is fit for the highways of America or any trail you may traverse all while providing maximum articulation at peak performance. 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.

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, Tom Woods, J.E. Reel)
