2007-18 Jeep Wrangler JK 4" X-Series lift kit, Vertex Reservoir shocks

The 4" X-Series lift kit for the Jeep Wrangler JK by Rough Country includes front & rear coil springs, front & rear upper and lower adjustable control arms with X-Flex joints, front forged adjustable track bar, rear track bar bracket, front sway bar quick disconnects, rear sway bar links, rear coil correction plates, front & rear stainless steel brake lines and four Vertex 2.5 Reservoir shocks.

The X-Flex control arms include Clevite OEM style rubber bushings, flex joints with 2.5" diameter body and huge 1.25" threads that are adjustable from stock up to 6" of lift. All joints are fully greasable. Upper joints pivot up to 20 degrees, Lower joints pivot up to 35 degrees. Coil correction plates correct the rear coil angle 10 degrees and allows the rear coil spring to function more efficiently.

The included front forged adjustable track bar has the added feature of being able to adjust and re-center the axles while installed on the Jeep. If you're a serious off-roader concerned with flexing, crawling and pushing the limits, this massive 16 lb track bar (nearly twice the weight of the JK factory track bar) is constructed of forged steel with rubber Clevite bushings and will provide unparalleled support to your Jeep. Installation is simple and adjustment is so easy. While others offer adjustable track bars, the Rough Country track bar is fully adjustable while on the vehicle - a significant improvement. Simply attach to the vehicle and dial in using the Rough Country innovative clamp and sleeve system.

If your driving style needs high performance shocks, check out Rough Country’s 2.5 Vertex 8-Stage adjustable reservoir shocks. With these shocks, you can perfectly dial in the ride type you need from smooth street ride to ultimate damping for off-roading demands. Each shock can be adjusted with a quick spin of the dial for exacting performance needs.

The Vertex shocks are a nitrogen-charged monotube design with an external reservoir with steel braided reservoir line for increased oil capacity and damping. This high-end shock features a 2.5” piston with a high flow 22mm chrome hardened piston rod that offers 56% more fluid capacity than the average 2.0 reservoir shock. The Vertex shocks have a 3-stage, fortified seal system with a steel body and CNC machined Billet aluminum accents for durability and great looks.
