Overview

Rock Krawler X-Factor Pro Mid-Arm Suspension Lift Kits

Rock Krawler X-Factor PRO mid-arm suspension lift kits are complete, bolt-in systems built for Jeep JL, JK, and JT applications, delivering big-travel articulation and trail-proven durability without sacrificing confident street manners. Each system is engineered around eight adjustable control arms and their high-misalignment joint combination to dramatically reduce factory bind and provide up to 95 degrees of misalignment for smooth flex. With extensive adjustability built in, you can precision-tune caster and pinion angle front and rear for stable tracking and predictable handling on the highway or the rocks. Ride quality comes from the tuned multi-rate coils paired with spring correction pads and track bar geometry corrections to help keep coils seated, reduce spring bow, and keep axles centered. Get a lift system that is designed to flex hard on the trail, then track straight on the drive home when you order the Rock Krawler X-Factor Pro mid-arm suspension lift kit best suited for your application.

More product features, items, and notes include:

* Offered at multiple lift heights so you can choose the stance and tire clearance that matches your build; availability varies by application
* Choose the shock package that fits your build: no shocks, Bilstein shocks (B51 suffixes), or their in-house RRD 2.25 in. IFP shocks (S1 suffixes); availability varies by application
* Listed components vary slightly by lift height/shock package
* Adjustable control arms machined from solid 7075 aluminum
* High-misalignment joint combination includes Adventure Series joints at the frame and PRO Krawler joints at the axle
* Improved rear roll center
* Gen-II sway bar links
* Coil springs are triple-rate on most applications, with Gladiator-specific front triple-rate and rear quad-rate tuning
* System architecture designed to be a base for future suspension expansion, including long-arm systems, if desired
* Bump stops are included with shock-equipped kits; no-shock versions require bump stops to be purchased separately
* Tire size can affect wheel backspace recommendations and require trimming of full OE-style fenders
* Bump stop height of 3 in. recommended for most builds (application dependent)
* If building with a spare delete, it is recommended to drop 1 in. of coil lift height for the rear
* If building an overland-style or heavily up-fitted build in the back, it is recommended to upsize 1 in. of coil lift height for the rear
* New front driveshaft recommended if you plan to off-road routinely
* Welding the rear cradle for use with 37 in. and larger tires highly recommended
* XR packages do not require their raised rear track bar bracket as the factory axle has a raised rear trackbar bracket; for their systems that do not have a rear trackbar, one must be added
* All lift heights based on Rubicon models for standard style build (front bumper and winch, rear bumper, and full-size spare)
