Review & Install Video
I'm Ryan from extremeterrain.com, and this is my review and installation of the JKS Control Arm Bracket Kit, fitting your 2007 and up JK, with 2 to 4 1/2 inches of lift. The installation of these brackets is a pretty simple one out of three wrench install, and you guys can do this in about 2 hours' time. When you lift your JK between 2 and 4 1/2 inches, you are going to naturally roll the axle a little bit, and that's going to really effect two different factors. One, it's going to affect your pinion angle upfront, which can cause some vibrations or some premature driveline wear. And two, it's going to change your caster angle, which will keep the steering wheel from centering itself automatically, which can give you a bit of a flaky feel when you're driving down the highway. Now, there are gonna be a couple of different ways to fix that. One is with a longer or adjustable set of control arms, either upper, lower, or both in the front of your Jeep. And there are a couple of different benefits to control arms. You're gonna have that adjustability where you can really fine tune things. Most control arms are going to come with a joint that's going to allow for some additional articulation, which is going to be really nice if you're off road, and you're not gonna lose any ground clearance. Or you can go with a set of geometry correction brackets like these ones. What these are going to do is still correct your pinion and still correct your caster but allow you to use those factory control arms. Now, you're not going to get the additional benefits of a control arm like that additional articulation, but these are going to save you significant amounts of money over getting a set of control arms. Those control arms are also not going to decrease any ground clearance, where these will decrease ground clearance a little bit. So it comes down to what you're really looking for out of your Jeep. Now, when you start comparing one set of geometry brackets against another, these are going to be about double the cost of the Rough Country Control Arm Geometry Brackets. Those ones are going to be a two-piece design, to these ones being fully boxed and welded are going to be significantly stronger. But, again, it comes down to your budget. If this is something you're only installing temporarily until you can afford to get a set of adjustable control arms in the front of your Jeep, maybe you save some money and you go with the less expensive ones. If this is something that's gonna be a permanent mod on your Jeep, you're not looking for additional ground clearance or for that additional articulation that you can get from control arms, you're just staying on the road, you want this as a permanent solution to fix your caster and pinion, then I think spending a little bit more on this set that's gonna be a little bit stronger is probably a good idea. These are built very strong and very stout, especially when you compare them to the two-piece design of some of the less expensive control arm brackets on the market. These are going to be a 7 gauge steel, they're fully boxed and welded. As I said, these are gonna be very, very strong. You're not gonna get any flex or any movement out of these brackets versus some of the other ones. Of course, they have a black powder coat finish on them, which is gonna help protect them against any rust or corrosion, and they are designed to bolt right into place. This is gonna fix your pinion, this is gonna fix your caster, and as sort of a fringe benefit, you're also going to flatten out your control arm angles a little bit. The benefit of that is it allows your springs and your shocks to absorb a little bit more of the bumps when you're driving down the road versus a steeper control arm bracket which can transfer a little bit more of that shock into the frame. It's not the main purpose of installing a set of brackets like this, but it will be a little bit of a benefit. To get these installed on your Jeep, all you need to do is park the Jeep on a nice level surface. Go ahead and unbolt the control arms at the frame, loosen up the bolts at the axle, but you don't have to completely remove those. You'll then bolt this bracket onto the control arm brackets that are already existing on the frame side, and then bolt the control arms into the new brackets before you tighten up all of the hardware. That's it really. You don't have to do any other disassembly of the axle. All you need to do is make sure you only install one set of these at a time. Of course, having the other side with the control arms fully bolted in place is going to keep the axle centered under the Jeep. You'll only want to unbolt two control arms on one side at a time. But this is something that's a very easy install. It might take you around 2 hours to get it done, but you can do with some traditional hand tools in your driveway. These control arm brackets are around $175. And as I said, there is a set on the market that are two-piece design. They're gonna be about half the cost. In my opinion, if you're looking to these for a long-term solution, you aren't concerned about the ground clearance loss, you don't want the additional articulation of the set of control arms, you're gonna be running these for the long haul, maybe it makes sense to spend a little bit more on this set to have them installed for a long time and take advantage of all the strength and the high quality of the build that you're getting with this set. Of course, if you're just looking to a set of geometry brackets as a short term solution before you can afford to get a set of adjustable control arms, then maybe it makes sense to save your money and go with one of the other brands. So if you have 2 to 4 1/2 inches of lift on your JK and you either don't plan on installing adjustable control arms or you just don't have the funds for them yet and you're looking for something to fix your caster and your pinion in the meantime, a set of control arm brackets like this is gonna get the job done and then again save you some money over getting control arms.So that's my review of the JKS control arm bracket kit, fitting all 2007 and up JKs, with two to four-and-a-half inches of lift, that you can find right here at extremeterrain.com.
