Overview

Rock Krawler Adventure X Series Mid-Arm 4XE Suspension Lift Kits

Rock Krawler Adventure X mid-arm 4XE systems are built for Jeep owners who want a bolt-in suspension that delivers excellent highway manners and serious trail performance. These kits pair tuned, triple-rate coil springs with a true mid-arm geometry package to improve ride quality, increase clearance, and keep your Jeep driving correctly after the lift. At the heart of these kits is the set of eight adjustable control arms featuring their service-free Adventure Series joints, designed to reduce factory bind and deliver up to 70 degrees of misalignment for impressive articulation. The adjustability also lets you dial-in caster and pinion angle (front and rear) for proper drivability and drivetrain geometry. 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 4XE 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
* Track bar geometry corrections (front and rear) help reduce spring bow and maintain stable handling
* Improved rear roll center, vehicle lean correction, and spring correction seats
* Gen II front sway bar links and adjustable front track bar
* 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
* 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)
