Rough Country X-Flex Adjustable Front Lower Control Arms for 2-6 in. Lift (07-18 Jeep Wrangler JK)
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.

These do exactly what you expect them to. Night-and-day difference from stock arms on a lifted jeep in both handling and correcting the pinion angles. They also weigh about 2x what the stock arms do, very beefy. Follow the below steps, and they are rather simple to install (done on a 2017 JKU). 1. Call Rough Country for measurements needed, it takes only a couple mins. Write them down. Don't use the generic measurements in the instructions, you need specific measurements for your jeep and lift height for best results. 2. Jackstand the front from the frame, place jack under axle and lift it up JUST a hair to take tension off the shock bolts 3. Disconnect sway bar links, remove bolt connecting track bar to the frame, remove lower shock bolts 4. Loosen ALL Control Arm bolts until you can spin the nut by hand (lower and upper), but do NOT remove. If you do, you will make your life much harder 5. Remove both lower control arms. Measure one from hole to hole, then apply that to the measurement RC gave you for the new arms. Build the new lower arms to length. Dont forget to tighten the grease points, they come shipped loose. 6. Install lower arms (frame first, then axle for all arms). You will need to push the axle some, maybe mess with the jack to line holes up. I was able to just push with my shoulder enough with little effort. Do not torque down bolts yet. Be sure to put the right one in for its side - pay attention to the direction of the bend compared to stock. 7. Repeat for upper control arms. I found in my 2017 JKU i did not need to cut the passenger bolt (the frame has a passthru) but on other years of JK it was needed. If you cannot align the holes with pushing alone, try jacking under the diff behind the axle to rotate the axle. 8. Once all arms are in, replace the lower shock bolts/track bar/sway links in that order. Once all are in, torque everything down. Be sure to pay attention to torque specs. 9. Reinstall tires, repeat for rear in the same order. Stick to this order strictly, and this isn't a bad job at all. Deviate, and you'll find yourself swearing and sweating very quickly. Also, dont forget to test steering afterwards, most likely your steering wheel will need recentered slightly.Helpful (8)

Perfect for the $
Jeep was a little “flighty” after installing 3-1/2 lift so I needed lower CAs to get back some positive caster. The CAs are beefy and seem to be very well built. Put them on following the manufactures specs, Jeep drove perfect 2000 miles to Moab. Wheeled it hard for 3 days and drove back home with no issues. Well worth the $!!Helpful (3)

Best Option for lifted JKUR
I'm an old crawler and try to pass my experience on to others any time I can. My 2017 Rubicon has a 3.5" lift, 35" tires on 17x10 Raceline wheels with -12 offset. I wanted better articulation and correct pinion angle. The answer was a complete set of Rough Country adjustable control arms. Easy install after quick chat session with Rough Country to get correct measurements for my lift/wheel/tire size. Result is better ride, better steering, and much better articulation. At under $800 this is the BEST option available! Now I like Teraflex products and in most cases, I'd choose theirs over other manufacturers. In this case their's was no real advantage. Double adjustable is NOT desired because, they can get out of adjustment much easier (not good). The control arms have more effect on driveability and crawling than any other component! This set will make a HUGE difference and save you hundreds over other options with no sacrifice on durability or function. If you haven't replaced your ball joints... do it right away. A lift, taller and heavier tires, more offset/wider stance all puts more strain on ball joints and when they go.... it's not pretty. Go with heavy duty like Ally USA or Teraflex ball joints and grease them at every oil change.Helpful (13)

After a 3 inch lift was put on the Jeep lost its smooth ride. Then when placing this control arm kit everything felt amazing. No vibrations the Jeep rides way better, and feels stronger. Those stock control arms are weak and junk compared to the Rough Country. For the price it is a steal! Would totally buy again.Helpful (7)

Very happy with the arms. Wish there was more info in the instructions for adjustment settings and setting the proper driveline angles, but very happy.Helpful (10)

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.Helpful (10)

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.Helpful (9)

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.
Maximum Lift What is the maximum lift range for this complete kit?
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.
Do they need any kind of maintenance?
These should be maintained and greased along with regular maintenance done to the jeep.
What all do you get for $199 a pair of arms 1 arm or all arms front and rear?
The current price of $199.95 applies to the following options: Pair of rear upper control arms ONLY, Pair of rear lower control arms ONLY, Pair of front upper control arms ONLY, Pair of front lower control arms ONLY.
These would work with your Rubicon Express lift.
These will not have measurements as this will vary based on your individual build.
These will provide slightly more clearance than OEM.
This is designed for 07-18 JK and JKU from stock height up to a Jeep that has 6" of lift.
In order to install these control arms the Jeep will have to be lifted up. Using either floor jacks and stand or a hydraulic lift.
You will want to install them while the Jeep has the rear end elevated for an easier time with installation.
Hello, we kindly request that you reach out to one of our Jeep enthusiasts via chat, email(email@example.com), or phone(1-844-887-6514) to further discuss your specific setup and build, so that we may better assist you.
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.
The Rough Country X-Flex Adjustable Control Arms will fit all 07-18 wranglers yes.
Thank you for your question! Yes, the control arms will correct the pinion and caster angle to recenter the axle.
