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.

Better than OEM replacement
Helps reduce the wheel hop. I don't think it would be good for heavy drag racing, but fine for a daily driver. Installing the center arm does require lowering the gas tank to get the mounting bracket out. I have a hoist in my barn so it took about 1.5 hours to install. Installing these control arms on the ground off of jack stands could take a full afternoon. I installed the lower arms with the grease zerks down. everything works fine. I didn't see a difference from side to side, just front to rear on the outer arms.Helpful (1)

Nice control arm.
Works well for controlling wheel hop and plants the rear well. Does clunk occasionally over bumps, but no big deal. If you don't want the clunk then order one of the aftermarket mounting brackets with it. Easy fit. (I already had aftermarket lower control arms.)Helpful (2)

And after about 2000 miles the poly bushing looks like it exploded. An I am unanble to find a replacement for it. And yes I torqued it to specs that were with the product at normal ride hight.

Good OEM replacement
Looks to be good quality, did not notice any difference in ride, but at 230,00 miles, thought it was time to replace. Replaced this along with the axle bushing, LCAs, panhard bar and its brace.Helpful (4)

SR Performance Rear Upper Control Arm
Very happy with this product, it does exactly as advertised. However, Install was pretty tricky due to its location. Also, when it came time to torque the bolts back down to the degree specified on the instructions (129ftlbs and 85ftlbs) It was virtually impossible to get a torque wrench into place without extensions which mess with the torque settings. But all in all, if you have the right tools, and know what you are doing, you should be fine.Helpful (4)

Goodbye wheel hop!
I installed new LCAs and got rid of most of the wheel hop on burn outs, but there was still a little chattering. Replacing the UCA eliminated all traces of wheel hop. I'm very happy with the results.Helpful (5)
Will this work if the car is lowered? I have a 2005 GT it is lowered 2.2 in the rear will this be a good upper control arm for my setup?
Yes. As a matter of fact it will improve how the car rides after being lowered.
Where can I get a replacement bushing for this upper control arm.
At this time we do not offer individual components for the SR Performance Rear Upper Control Arm.
I need the bushing for sr performance upper control arm for 05/10 mine looks like it exploded thanks for any help
I'm sorry to hear that happened to your upper control arm, please contact our customer service department so they can assist you with this! The telephone number is 1-877-887-1105 and we can be reached 7 days per week betwen 8:30AM EST and 11:00PM EST.
It is shorter than the factory control arm , is there any problem if i install it?
The SR Performance Rear Upper Control Arms will be the same length as your factory Upper control arms. If your Mustang is lowered, we recommend the adjustable to allow for better angle adjustment over the fixed control arm.
Do i have to buy Mounting Bracket with this control arm?
The SR Performance Rear Upper Control Arm will be a direct bolt on that does not require any mounting brackets.
The SR Performance Rear Upper Control Arm will carry a 1 year warranty, including the bushings. Contact our Customer Service Department so that we may best assist you with this. Please take note that any control arm should not be tightened until the suspension is at ride height, otherwise premature bushing failure will occur.
If you are looking to replace both sides, you will need to purchase two of these lower control arms.
While some may have modified the SR Performance Rear Upper Control Arm (05-10 All) to fit a 2011 GT, we can only confirm fitment of this Rear Upper Control Arm on 2005-2010 model Mustangs.
Yes it will take off maybe .1-.2 second of 1/4 mile. If your lucky .3 if you get a perfect lauch
You only need one upper control arm.
