    Review & Install Video

    I'm Ryan from and this is my review of the Rough Country X-Flex Adjustable Control Arms fitting all 2007 to 2016 JKs. These are available in pairs or as a set of all eight. Anytime you lift your JK, you'll be moving the axles of the vehicle toward the center. A set of adjustable control arms will allow you to re-center the axles underneath the wheel wells. Adjustable control arms also have a couple of other benefits. When you lift a solid axle vehicle, you'll change the pinion angle and the caster angle in the front axle. Bad pinion angles can cause driveline vibrations and premature drive shaft wear, and a bad caster angle can cause a flighty feel while driving down the highway because the steering wheel doesn't want to re-center itself. A set of control arms like this are single adjustable, which helps to keep the cost down a little bit, and the fact that these are available as pairs allow you to build up to a full set over time, saving you a little bit of money. The first thing you'll notice when you take these control arms out of the box is how beefy they are, especially when you compare them to a factory control arm like this. These are really strong and that's exactly what you need, especially when you have big tires on your jeep and you're off-road abusing your suspension. The way these arms are designed is that they have a rubber bushing on one end, which is really similar to your factory bushing. and the other end is Rough Country's X-Flex spherical joint. These joints will provide you with 20 degrees of articulation on an upper control arm and 35 on a lower. What that means is that along with re-centering your axles, adjusting your pinion angle and adjusting your caster, these control arms are going to give you additional articulation and additional performance off-road. One of my favorite parts about the X-Flex joints is that they're completely rebuildable. Rough Country provides you with all the parts you need to rebuild those joints in the event that they do start to make a little bit of noise or get a little bit loose. Getting these control arms installed in the jeep is a pretty straightforward process. You actually follow many of the same steps that you would if you were installing a full lift kit. The first step is to support the jeep by the frame and remove or loosen anything that keeps the axles from completely drooping. That means you're going to be loosening or removing your brake line brackets, sway bar end links, track bars and shocks. Once you completely sagged the axles from underneath the jeep, you will be able to remove your springs, and the axles will be completely unloaded. At that point, you can just remove the bolts holding the factory control arms in place and install the new ones. Now because these are single adjustable control arms, you will have to adjust them with the jeep in this condition. You won't be able to put everything back together and ingest them on the jeep like you would with a double adjustable control arm. That does make installing a double adjustable a little bit easier, however these single adjustable arms are less expensive, so it's a good way to save a few dollars. This whole process can take place after you've installed the X-Flex joint in each of the control arms. Again that's a really simple process following Rough Country's installation instructions. And they even provide you with the tool necessary to install them. The whole process should take you about four hours if you're installing a full set of like eight control arms or a little bit less time if you're only installing a couple. And you won't need any specialty tools, just the jacks and jack stands and some traditional hand tools, although air tools will definitely speed up the process. Let me just say, I know what Rough Country's reputation was for control arms. In the past, they were known for not making the highest quality control arm and they were known for their joints wearing out prematurely, but I have to say these are not the control arms of the past. These X-Flex joints seem to be really strong, they are completely rebuildable, they seem really solid, and these control arms really seem like they're worth the price. There a lot of companies making control arms, and they all have their sort of proprietary spherical joints. They all say they're stronger than another one or provide more articulation than another one, but honestly, for the price you have to pay for these, these seem like a really nice adjustable control arm option. So if you've lifted your jeep and you're looking for a set of adjustable control arms to re-center the axles and the wheel wells, adjust your pinion angle and adjust your caster angle, these are a really nice set of control arms that are going to be both strong, rebuildable, and provide additional articulation over your stock arms. So that's my review of the Rough Country X-Flex Adjustable Control Arms fitting all 2007 to 2016 JKs. They can find right here at

    Better Strength and Safety. Your Jeep Wrangler will have improved range, strength, and safety for off-road applications with these Rough Country X-Flex Adjustable Control Arms. With the adjustable retainer rings, you'll have an easier time preloading the brushings before installation. The control arms' threaded chamber inside the housing gives you the ability to modify the amount of compression on the bushings and friction on the spherical ball making your suspension run smoothly.

    Top-Quality Construction. These adjustable control arms are made to withstand heavy-duty off-roading. The ball-in joint, large 2.5" diameter body and 1.25" threads, they can handle the beating your Wrangler's suspension would take. The control arms are made with high-quality material that won't break or rust quickly as they'll extend the longevity of the joints.

    Easy Installation. Installation isn't complex when installing these Rough Country X-Flex Adjustable Control Arms as they are made for easy maintenance and adjustments. All it takes is a few quick twists and your joints will be installed.

    Application. The Rough Country X-Flex Adjustable Control Arms are specifically designed to fit on all 2007-2018 Jeep Wrangler JK models.

    5 Top Rated Questions

    Are these arms able to be short enough to use in place of the stock arms on a 4 door rubicon and then later on be lengthened to fit the proper and desired lift springs and shocks?

    • Yes, the Rough Country X-Flex Adjustable Control Arms can be adjusted to factory length and then later adjusted to compensate for a lift.

    Will I need to extend the driveshaft on both axles?

    • The Rough Country X-Flex Adjustable Control Arms would not effect the ability to extend your driveshafts. Depending on what lift height you have you may over extend your stock driveshafts, requiring you to extend your driveshafts. Each Jeep reacts a little differently to being lifted but usually between 3-4 inches of lift and up you need to replace at least the front driveshaft if not the front and rear driveshafts.

Read several forums, but unsure. Do I just need lower arms on front and rear? Or Upper and Lower on front and rear? Want all needed materials prior to installation to prevent wear and tear on existing equipment. Also, do drive shafts need to be replaced on this lift w/ extended arms? Thanks in advance. 1 answer

      Rc arms

      The arms are a good fit and easy installation. My only complaint is Rancho puts a replacement bolt in the kit for the one bolt that hss to be cut off but the bolt is a different thread pitch so it doesn't fit the nut. Had to run down to the hardware store for correct bolt.

      RC Adjustable Front Lower Control Arms

      I paired these bad girls with a set of Rough Country's upper control arms and eradicated the death wobble. Before when I'd be driving between 30-50 upon hitting a bump my Jeep would go into death wobble. After this upgrade, which I have to say is worth the $400 if you are plagued by the death wobble, it was like brand new. Since my Jeep is lifted 3 inches, I had to call customer service and have them give me the correct lengths. They were very helpful.

      X Flex quality and Price

      Impressed with the quality of this product and price compared to others from other companies I researched. Received them quickly too. Just in time to be installed to have a full front and rear alignment being we were headed to the Bantam Jeep Festival in Butler Pa. These quality parts helped us with a smoother and straighter ride there and experience the trail rides that were happening there as well.

      Great for price, terrible threads.

      Quality seems legit but it took me 2 hours to put the front lower contril arms together. Had to run to Home Depot to get new set screws because the machined threads on the adjustible side were either painted after they were threaded or just threaded very poorly. I ended up breaking off a piece of metal and welding it in to keep the the rings from backing out. If you're doing the yourself....hope youre handy!

      I had a hard time with the c clips,1 of the grease fittings would not go in due to a metal spur and they never said any thing about needing a 1 3/4 " wrench. The price was a lot less than all the rest.

      The parts look like they cost hundreds more.....and the ride feels airbagish lol. In a good way. Perfect for anyone on a budget , but needs parts that exceed the stock limitations. Without compromising the design, sometimes even cheaper than stock parts...

      Vibration eliminator

      I have 4" RC lift, Tom Woods front DS with AEV drop brackets but still had a vibration. After this install the vibration was gone. The bad part was the quality control of the threading. One grease fitting would not go in. Also the threading on the control arm itself had to be cleaned up prior to assembly. Besides this it was an easy install.
