Review & Install Video

Hi I’m Justin with and I’m going to be breaking down 2 rear upper control arm options both from SR Performance, I have with me their adjustable and non-adjustable option, both fitting the 2005-2010 Mustang. SR Performance is a company that’s been earning the respect and attention of a lot of Mustang enthusiasts lately, thanks to their budget friendly yet high quality performance and suspension components for all generation Mustangs. IF you’re not already watching this video on and you’d like to get back to our site, to read more about SR’s killer lineup, just click on the link below. The job of an upper control arm is to locate the axle side to side and prevent any pinion angle changes otherwise known as axle rap or axle windup. The factory stuff utilizes some pretty soft rubber bushings, which are notorious for flexing or distorting on hard launches, and aggressive cornering which can cause a bunch of wheel hop, and inconsistent handling. If you want to learn more about making your Mustang handle better and reducing your wheel hop, well, then you have to subscribe to our YouTube channel by clicking the link below. Here you can check out numerous suspension overviews on all of our products, in addition to some pretty cool suspension builds that we’ve done to our own cars. Both of the options I’ve got on the table should do an excellent job of dropping your 60ft times, and reducing wheel hop and axle deflection, while increasing your rear end group by using superior materials compared to your factory control arms. The non adjustables here feature a strong TIG welded steel construction, along with these polyurethane bushings which are greasable. Poly bushings will do a great job of reducing any noise vibrations or harshness, that you otherwise might find on the spherical bearings found on the adjustable control arms here. In my opinion this is a great option for someone who enjoys doing some spirited driving with their Mustang, maybe just a few track days, and just wants to replace those soft rubber factory bushings in the control arm. The adjustable option from SR Performance is for someone who is serious about their track performance, and would ultimately like to dial in their optimum pinion angle settings. For only a few bucks more compared to the non-adjustables, you’re getting full on car adjustability, strong TIG welded steel construction, and these spherical hind joints here, which are going to take all the unwanted movement out of your Mustang’s rear end. Both options aren’t terribly difficult to install and should only take you a couple of hours in the garage using some pretty basic hand tools. Whenever you switch out your rear upper control arms I recommend getting your pinion angle checked out just to make sure everything’s within spec, especially if you decide to go with the adjustables. An incorrect pinion angle can cause unwanted traction, wear and tear on your pinion bearing and drive train vibrations. If you’re not quite sure which option would be best for your application, you should get in touch with one of our Mustang experts, you can call them at 855-422-7439, or shoot them an email at So if you’re on the endless quest to make your Mustang perform better on the street, or at the track then you have to check out a set of these adjustable or non adjustable control arms from SR Performance, right here at

Improves Traction. Everyone knows that you're going nowhere fast if you can't "hook up" off the line, that's why SR Performance designed their Adjustable Rear Upper Control Arm to provide better traction, quicker launches, less wheel hop and as an added bonus improved 60ft times.

On-Car Adjustable. The SR Performance S197 Mustang Upper Control Arm is on-car single adjustable, thanks to the spherical rod end bearing, allowing you to dial in your suspensions settings "on-the-fly" to be sure you go straight down the track every time.

Tubular Steel Construction. Made in the USA from TIG welded heavy duty 1.5" steel tubing for superior strength, SR Performance completes their Rear Lower Control Arms with a black powder coat finish for long lasting durability and good looks.

Aluminum Bushings. This SR Performance upper control arm features an Aurora (heim joint) spherical rod end bearing and aluminum bushings. The result is great traction during straight-line acceleration and predictable grip during hard cornering.

Application. This SR Performance Adjustable Rear Upper Control Arm with spherical rod end bearing is designed as a direct bolt-on upgrade for all 2005 to 2010 Mustangs, including the V6, GT, Bullitt and Shelby GT500 models.

Re-aligning the rear axle? I have heard that you can use this to re-center the rear axle after lowering the car. Is that true?


  • NO. An adjustable UCA is used to change the pinion angle. Which you may be necessary depending on how much you lowered your car. However to re-center the rear axle under the car you need an adjustable panhard rod.

Re-adjusting rear end after lowering? I've heard that you can use this to realign the rear axle of the car. I'm getting the SR Performance lowering springs put on and I've been told that you need something to move it back. Can this do that along with everything else it does?


  • NO. As stated in above comments, this only adjust the pinion angle of the axle. You need an adjustable pan hard bar to move the axle back to center.

Answer This Question

Do you need the adjustable lower for this to work? Can you use this with lowering SR springs and adjustable panhard bar together? Thanks


  • No you do not need ajustable LCA's to make this work.

    Have to give it to American Muscle for getting this product to me so quickly! Once I opened it I could tell it was much much beefier then the OEM part. Install was rough at first, but once I had the old one off the new went on and was adjusted in less then 30mins. Good strong product and would recommend this to anyone!

    Good, strong looking piece!

    I received the part in 4 business days, not bad considering it went across the country. Packaging was excellent and piece is solid. Install is easy, relatively speaking. The adjustability will be nice once the car gets lowered!

    Did what it was supposed tO

    Put this on my 06 v6 to correct the pinion angle, if you live in an area where rust is a problem be warned it'll make this a pain. The gas tank straps wouldn't break loose and I didn't want to break them to I removed the arm from the bracket itself, also if you torque the bolts to the recommended torque you may need assistance. I didn't weigh enough to torque the bolts under the car so I got em as tight as I could

    I installed adjustable lower control arms at the same time, all spherical rod ends. Only a slight increase in noise and vibrations but that's expected when you replace soft rubber insulators with a much more precise spherical fastener. It's not may daily driver, maybe once a week or weekends. Initial reactions are the car seems much more precise in the corners, and the launch is improved. I haven't had the opportunity to sort and adjust much yet but I think this product will help me dial the GT in for the drag strip as well as track days, autocross or what ever I decide to go do.
