Rock Krawler 4.50-Inch X-Factor X2 Stage 2 6-Inch Stretch Long-Arm Suspension Lift Kit with Coil-Overs (07-18 Jeep Wrangler JK 2-Door)

The Rock Krawler Suspension 4.5" X - Factor X2 6" Stretch COILOVER Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. 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). 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. 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.
The Comp System (Front Coilovers w/ Rear Coil Combination) is ideal for those that want the adjustability and performance of coilover racing shocks up front, but still want to use their Wrangler to carry small loads or tow small trailers. There are two options for the Comp Systems you can choose from. The standard or Stage 1 System features 2 5/8" RRD Racing Coilovers w/ Remote Reservoirs up front paired with matching 2 5/8" RRD Racing Shocks w/ Remote Reservoirs in the rear for a well tuned package. Or you can opt for the Stage 2 Comp System which will include Fast CD (Compression Dampening) Adjusters on the coilovers and rear shocks for an even greater level of tuneability. 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)
