Tackle the Toughest Trails. Add the best in off-road articulation to your JK with Rough Country's 4 in. X-Series Long Arm Suspension Lift Kit. With 4 inches of lift that can accommodate tires up to 35” x 12.5” mounted on 17" wheels, there are no obstacles you can't tackle with Rough Country's Y-link suspension setup. For those off-roaders who are serious about flexing, crawling, and pushing your Jeep to its absolute limits, this kit features an upgraded forged adjustable track bar. Combine that with beefier Performance 2.2 Series Shocks, lifted coil springs, and adjustable control arms and you have a rig that's ready to go where most people wouldn't dare.

Performance 2.2 Series Shocks. Rough Country's Performance 2.2 Series Shock Absorbers are engineered to meet the demands of serious off-road enthusiasts. 50% larger than standard shock absorbers, 2.2 series shocks feature a massive 41.4mm bore with a 17.5mm chromed hardened piston rod. An internal rebound disc spring provides greater energy absorption during extension, while an external jounce bumper absorbs energy during suspension compression for an agreeable ride on and off-road.

Lifted Coil Springs. The front and rear coil springs included in this Rough Country 4 in. Suspension Lift Kit have been engineered to work perfectly in conjunction with the other components of the kit. These springs will not only aid in lifting your Wrangler for increased clearance, but they will also help to provide a smooth comfortable ride. Rough Country also includes a set of Coil Correction Plates to correct the rear coil spring angle by 10 degrees, allowing them to function more efficiently.

Forged Adjustable Track Bar. This Rough Country's 4 in. X-Series Long Arm Suspension Lift Kit features an upgraded adjustable Track Bar. Manufactured from forged solid steel for superior strength, this 16 lb. Track Bar boasts a beefy construction that will dwarf the original bar in comparison. Straight forward to install, this Track Bar is fully adjustable allowing you to fine tune your JK's suspension.

Adjustable X-Flex Control Arms. The Rough Country X-Series Lift Kit consist of 2-inch lower control arms that the upper control arms mount to, thus creating a Y-link suspension. Both the upper and lower control arms are manufactured from tubular steel for extra rigidity and are completed in a durable black powder coat finish. These X-Flex control arms are fully adjustable thanks to the included X-Flex joints. These joints are greasable and rebuild-able thanks to OEM style Clevite brand bushings.

Heavy Duty Skid Plate. To protect your Wrangler's transmission and transfer case from off-road hazards, Rough Country includes a heavy duty skid plate. This Skid Plate is fabricated from 1/4" thick steel and is completed in a textured black powder coat finish.

No Welding Required. Rough Country designed their X-Series Long Arm Suspension Lift Kit to be installed with no welding needed, making it a bolt-on kit. However, it should be noted that cutting and drilling is required for installation. With all the necessary hardware included, this Lift kit can be installed in about 8 to 10 hours time.

Lifetime Replacement Warranty. Rough Country Suspension Systems offers a Lifetime Replacement Warranty on most suspension products. All products are warranted to be free from defects in material and craftsmanship for the life of the vehicle if utilized in accordance with the manufacturer's instructions for installation and operation of said products. Subject to the terms and conditions, please see manufacturer's full warranty for details.

Application. This Rough Country 4" X-Series Long Arm Suspension Lift Kit with Performance 2.2 Shocks is designed for use on 2007-2011 4-Door equipped Jeep Wrangler JK models. Does not fit 2-Door models.

Application Note. For automatic transmission Wranglers: Due to the 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. This generally 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 this driveshaft if needed.

      4 Top Rated Questions

      Do i need to replace my stock driveshaft?

      • With a 4 inch lift or higher it is recommend to upgrade the drive shaft. And due to the design of this lift kit it is recommended to use a thinner aftermarket driveshaft to allow for improved clearance during heavy articulation.

          Worth the money

          I got this lift when my 2016 jeep had 1000 miles on it,I didn't know at the time that you had to cut all of the factory control arm pockets off of the kinda scared me that I had to do that but I said whatever and dove in.after I cut all the factory pockets off of it,it was pretty much smooth sailing.overall I would recommend this lift to anyone who's looking at it.i haven't had any problems with mine so far and it sits really nice,performs rather nice off road.only changes I would recommend is the grease nipples to be changed to smaller ones and flipped towards the bottom of the frame instead of the road,to keep from ripping them off on rocks. Overall if you're reading this and interested in this lift than buy it.and DO NOT cut your exhaust there is absolutely no need to do that.i learned that the hard way,and there is no need for the exhaust spacer. The lower control arm will not hit the 180 loop in full flex,I would recommend front driveshaft because the factory is to think and it will bang around on a few things underneath,I would also recommend rear driveshaft because at full flex it puts the rear in a odd position,the rear isn't "needed" but in my cause I bought front and rear because there better than factory and prevent problems down the road.hope I could help.
