The new 4.5in X-Series N2 features a transfer case drop kit, forged adjustable track bar, stainless steel brake lines, and sway-bar disconnects. A set lifted coil springs and all-new rear lifted leaf springs help your XJ gain a total of 4.5in in lift - plenty of clearance for 32in tires. This X-Series kit features Rough Country's X-Flex Control arms in the front upper and lower position. X-Flex Arms are fully adjustable, and feature a ball-in joint, massive 2.5in diameter body, and huge 1.25in threads. X-Flex Control Arm Joints have long offered considerable range, strength, and safety for off-road applications - but it doesn't stop there. X-Flex Joints now feature Adjustable Retainer Rings, allowing you to preload the bushings by compressing them prior to install. These NEW bushings are fitted with interlocking grooves that completely encase the ball joint for a firm grip. Made of high-quality 88 Durometer Urethane, these bushings retain the memory of their original shape, are weather resistant, and offer a much longer lifespan. This X-Series Lift now also offers N2.0 shocks; outfitted with rubber bushings and armed with 10-stage velocity sensitive valving, chromed hardened 9/16in piston rods, and massive 1 3/8in bores; allowing for a super smooth highway ride and outstanding control in rugged off-road situations - all from the same shock. So if you're looking for longevity and an uncompromised ride, look no further. Rough Country's X-Series N2 features the best of the best in off-road hardware. Read More

  1. Happy customer - Posted by: Jon (6/1/15)

    Gained more lift than i thought i would and am very happy. The only problem is that i want to go higher!!

    One thing though, the directions say for the sway bar bolt on the axel is a Torx bolt, this is true but this bolt is pressed into the axel bracket and you will need to use a torch to heat up the bracket to hammer the bolts out. The directions do not state this, but it's no big deal.

  2. good - Posted by: tstreet76 (4/7/15)

    Ok the instructions where well writen installation was a breeze other than the typical rusted and seized up bolts typical on the xj's. My only complaints with the lift are 1) and this is a personal one was a little disappointed that some parts where made over seas would have liked and all american made product 2)the crush washers for the brake lines where inferior had to go purchase all new ones, once again probably from being made in china. Now besides those issues its seems like a good system.

  3. Great Product and warranty to back it up! - Posted by: mike (2/20/15)

    Bought lift from my cousin's shop here in South Texas. I love the look of my XJ 4.5" taller, just need to work on bigger tires.

  4. Fantastic lift and value - Posted by: Barrett (11/17/14)

    In the past six months I have installed 3 rough country lifts. Each one of these lifts have been fantastic! I have never installed lifts before but the instructions were easy to follow and the videos that I could find we're also helpful. The first lift I purchased for my daughter was the 3" x series lift which installed with ease. I made sure to spray all the areas that I needed to with PB Blaster a week Pryor to install. The next two lifts were for my sons XJ and then mine. These were the 4.5" x series lift with the full leaf springs. Although these lifts are a bit harder to install, they are well worth it! My wife says I need to take stock in rough country. Maybe she is right.

  5. Excellent - Posted by: Greg (9/3/14)

    We picked this kit for our project vehicle after some hefty research.After the research we came to the conclusion that Rough Country was an extremely reputable company to deal with. Although we had some issues with removing stock components, the install of the 4.5" x series lift was however extremely easy, directions were spot on , and all parts are built extremely well. Customer service was excellent as well, shipped it the same day we ordered and even tracked it for us after UPS had a hiccup with it. 12 Star will be recomending Rough Country to anyone interested in a upgrade in suspension. One of the best things is that after measuring before install and after we gained almost 5.5". And we only have 31x10.50 tires on it currently.
