Overview

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

Rock Krawler Adventure Series mid‑arm 4XE systems are built for Jeep owners who want a complete, 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 are the two non-adjustable control arms with service-free Adventure Series joints installed at each end. The Adventure Series mid-arms feature 35 degrees of misalignment when paired with Adventure Series Joints at the frame connection and axle. This adjustability also lets you dial-in caster and pinion angle (front and rear) for proper drivability and drivetrain geometry. The included track bar geometry corrections (front and rear) and spring correction pads/seats help reduce spring bow and maintain stable handling, along with a level stance. 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 Series mid-arm 4XE suspension lift kit best suited for your application.

More product features, items, and notes include:

* Improved rear roll center
* Triple-rate coil springs for comfort and controlled response on varied terrain
* Front and rear track bar geometry corrections to re-center axles and preserve handling
* System architecture designed to be a base for future suspension expansion, including long-arm systems, if desired
* Adjustable front track bar
* Rear track bar relocation/correction components, spring correction pads/seats, and sway bar link components (kit dependent)
* Bump stops are included with shock-equipped kits; no-shock versions require bump stops to be purchased separately

* 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
