I'm Ryan from ExtremeTerrain.com 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 ExtremeTerrain.com.

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.
On a 2015 JKU Saharah, I have purchased a 3.25" rough country lift. I want to make sure the pinion and castor angle are going to be correct. Would these control arms fix and make correct? 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.
I read through the answers and at one point you mention that these arms will work on a Jk with up to a 6in lift and then later when asked what the max lift would be for these arms, you answered 3.5in. Can you elaborate?
We do apologize for any confusion, that looks like a customer submitted answer. We will get that removed and updated! The Rough Country X-Flex Adjustable Control Arms will fit a stock JK or up to 6 inches of lift.
Will This fit a 2012 JKU?
The Rough Country X-Flex Adjustable Control Arms will fit all 07-18 wranglers yes.
2014 wrangker jk 2d 4" suspension lift ,flat fenders 37" tires already have front control arms. looking to get the back. could the adjustable arms push the rear axle back a little further to get tire further away from pinch weld .
Thank you for your question! Yes, the control arms will correct the pinion and caster angle to recenter the axle.
I was thinking that to get the adjustments I need, it would only require lower control arms being adjustable, is this correct or do all 4 need to be adjusted?
Unfortunately without more information on your Wrangler's build, we would not be able to advise you on if this is what you require. Please contact our Customer Service Department so that we may best assist you with this.

Upgrade
It was an easy and simple install. All I had to do was match them up With the old ones and they dropped right in for me. I'm about to test them out on the trails, wish me luck...

Problem solved
Fixed my steering problem. Great quality. Would recommend.

Excellent
This is an excellent product. It gets you into the upgrade. The installation was very simple with detailed directions. Easily adjusted and installed.
November 01, 2017

They do the job only thing is they squeak a lot even with it freshly greased.

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.

X-Flex
Great looking, well built and easy to install. They corrected the caster and bumpstear so my JK handles great.
February 27, 2017
Good Product
Fit was pretty easy to get on the Jeep. Haven't had much use with them in place yet, but seems to ride 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!

Excellent add on when installing a lift kit!
Great addition if you're planning to install a lift kit!!!
March 10, 2016
they did not go together very easy.
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.

Best Buy
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.
