Hi I’m Justin with AmericanMuscle.com 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 AmericanMuscle.com 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 support@AmericanMuscle.com. 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 AmericanMuscle.com.

You can’t beat the price and it’s a quality control arm and fully adjustable. This will dial in pinion angle and firm up your launch when compared to the factory rubber bushing. Well with the money.Helpful (4)

This UCA seemed great for a few weeks, but then it got very noisy, inspected it and torqued everything again and it's still noisy. It makes a creaking popping noise when accelerating and making turns, the problem gets worse when there's more weight in the car. Don't know if I got a defective product or not, no other reviews I've read describe what I'm going through.Helpful (6)

I purchased this part to fix my pinion angle after I installed Eibach sportlines and developed a pinion seal leak. The installation instructions were helpful. I had to remove the gas tank strap torx bolts and pry the tank down from where the UCA and Mount are using a pry bar making sure to support the fuel tank. I used ramps to level and load the suspension after installation of the UCA and set the pinion angle to -1 degree (recommended for spherical bearing / aluminum bushings). My Mustang seems faster and tires seem to break loose ALOT easier. I haven’t noticed noise, vibration or harshness yet. I used the stock mount and put loc-tite on all the bolts as a precaution.Helpful (8)

Upper control arm
The Rear upper control arm really help out a lot with my wheel hop and pinion angle. I would recommend using this part if you have lowered your car.Helpful (9)

this is a must if you have lowered your mustang. install was a pain but I pre set and checked pinion angle was -2deg, no more noise in 1st gear and pinion seal leak stopped. any lowered mustang should have pinion angle checked to avoid any damage to drive train. also lost 90 of rear wheel hop good part for the money.Helpful (9)
I've installed this product along with the sr adjustable lower arms, j m double adjustable panhard bar and the sr springs. With all metal bushings practically, how much noise should be expected in comparison to poly and rubber?
Using solid and spherical bushings will significantly increase NVH, as well as increase stress on the control arm mounts under hard acceleration, due to their nearly nonexistent deflection.
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.
Do you need the adjustable lower for this to work? Can you use this with lowering SR springs and adjustable panhard bar together? Thanks
You don't need the adjustable lower control arms to use this upper. When you install adjustable lowers you put to them stock length when you install them. You can also use this with lowering springs and a adjustable panhard bar. The upper adjusts the pitch of your rear end if you need to and gets rid of the unwanted flex along with the better lowers.
