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

It’s time to get that Jeep of yours spruced up and ready to attack some mud, rocks, hills, trails, and so much more! This 4" X-series lift kit for the Jeep Wrangler Unlimited by Rough Country has what you need to make this happen. 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. On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission pan tearing the factory boot and rubbing on the shaft. Generally this occurs during heavy articulation when front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper procedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase clearance between the transmission and front driveshaft. Rough Country does offer these replacement driveshafts.

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.
