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

Rock Krawler X-Factor Pro mid-arm diesel suspension lift kits are engineered for Jeep owners who want a bolt-in system with serious articulation, confident street manners, and the adjustability to properly set suspension geometry after lifting. These diesel-specific kits are built around eight adjustable control arms machined from solid 7075 aluminum, delivering high strength with reduced unsprung weight and the proven X-Factor geometry that helps reduce factory control arm bind for smoother travel on and off the road. With adjustable upper and lower arms front and rear, you can precision-tune caster and pinion angle to dial-in handling and driveline angles after the lift. Spring tuning is designed for real-world performance and to better support the vehicle's rear load demands. Track bar/geometry corrections and included adjustable track bar components help properly center the axles for stable road manners and predictable steering. 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 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; 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
* Adventure Series joints at the frame (maintenance-free) and PRO Krawler joints at the axle
* Each system uses specific joint pairing to maximize movement, providing up to 95 degrees of misalignment for excellent flex without sacrificing stability
* Wrangler JLU kits use tuned triple-rate coils, while Gladiator JT kits use triple-rate front coils with quad-rate rears
* Improved rear roll center
* System architecture designed to be a base for future suspension expansion, including long arm upgrades, 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
* 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)
