Overview

Rock Krawler X-Factor Pro Mid-Arm No Limits Diesel Suspension Lift Kits

Rock Krawler X-Factor PRO No Limits diesel mid-arm systems are purpose-built for diesel-powered Jeeps that need real articulation and confident street manners from a bolt-in suspension package. Built around eight adjustable 7075 aluminum control arms, these systems are designed to reduce factory bind and provide up to 95 degrees of misalignment when paired with Rock Krawler's joint package, so you can fine-tune caster and pinion angles front and rear for stable drivability. The No Limits components include front sway bar links engineered to work with the factory electronic sway bar disconnect on select models. Tuned coil springs, plus spring correction and track bar geometry corrections, help keep the ride controlled, the coils seated, and the 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 No Limits diesel 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
* 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
* All control arms feature 7075 aluminum construction, putting the X-Factor PRO strength/weight advantage and corrosion resistance where it counts
* Service-free Adventure Series joints at the frame and PRO Krawler joints at the axle for a blend of vibration control and articulation
* Tuned coil spring packages by platform (four triple rate springs for JL/JLU; triple-rate front/quad-rate rear for JT)
* Track bar geometry addressed with adjustable front track bar plus a rear track bar relocation bracket (JL/JLU kits also include a rear adjustable track bar)
* 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)
