Overview

Rock Krawler Adventure X Series Mid-Arm Suspension Lift Kits

Rock Krawler Adventure X Series mid-arm suspension lift kits are engineered for Jeep JK/JL and JT owners who want a bolt-in suspension system that delivers excellent road manners and serious off-road articulation. Adventure X systems earn the "X" name by including eight adjustable control arms equipped with service-free Adventure Series joint packages, designed to reduce factory arm bind and provide a total of 70 degrees of misalignment for smoother flex and increased wheel travel. With extensive adjustability built in, these kits allow precision tuning of caster and pinion angle front and rear to help restore correct geometry after lifting. They also feature multi-rate coil springs tuned for ride quality and controlled off-road response. To improve handling and maintain proper axle position, systems include spring correction pads/seats and track bar geometry corrections to help center axles without compromising on-road stability. 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 Adventure X Series 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
* Multi-rate coil springs include tuned triple-rate versions on Wrangler applications, with Gladiator systems using triple-rate front coils and quad-rate rear coils to match the JT platform
* Correction pads/seats to help minimize spring bow
* Track bar geometry corrections include rear track bar relocation solutions (application dependent)
* Improved rear roll center
* Front and rear extended brake lines (application dependent)
* 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 (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
* 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)
