    What's up guys? I am Justin with and welcome to my complete breakdown of the RTR Tactical Performance Rear Adjustable Upper Control Arm and Mount fitting your '11 to'14 Mustang.Your rear upper control arm is just one of three links in your S197's rear suspension, the lower control arms being the other two, and as you might expect, is very important when it comes to both your traction and your handling performance, but even more important when it comes to adjusting your instant center and also your pinging angle, especially for those of you out there with lowered Mustangs and one-piece drive shafts.Vaughn and his team at RTR took a tactical approach when it came to designing and developing an adjustable rear upper control arm that will help you and your Mustang no matter what the situation. Whether you're trying to drop the 60-foot times at the drag strip or whether you are trying to put that power down coming out of turns on the back roads or at the race track itself.Now the result is this very easy-to-adjust upper control arm while on the car, it's going to eliminate any wheel hop and excess movement of the rear axle itself by eliminating those soft rubber factory bushings that do a great job of soaking up all the road noise and vibration but leave a lot to be desired when it comes to all out performance. But without a doubt the star of the tactical performance adjustable rear upper control arm here has to be the maxi bushing that is pressed into the forged end.Now this thing is actually going to give you all of the performance of a spherical bearing or a rod end joint without the excess of noise vibration or harshness or NVH as it's often called. Another nice thing about these bushings is that they are completely maintenance-free, meaning you're never going to have to grease it throughout its lifespan. Getting the upper installed is a little bit more involved compared to those lowers mainly due to the fact that you have to access a pretty big bolt underneath the rear seat in addition to the work you need to do underneath the car. So of course, make sure you have your jack and jack stands ready and leave yourself a couple of hours from start to finish.As always guys, don't forget to reach out to a Mustang expert anytime if you should have any questions. So if you guys are really looking to lock down that rear axle, eliminate any wheel hop, improve your traction, and have the ability to really adjust that pinion angle, then you want to check out the RTR Tactical Performance Adjustable Rear Upper Control Arm here at

    Improves Traction. Everyone knows that you're going nowhere fast if you can't "hook up" off the line, that's why RTR designed their Tactical Performance Adjustable Rear Upper Control Arm to provide better traction, quicker launches, and to eliminate dreaded "wheel hop".

    On Car Adjustable. The RTR Tactical Performance Adjustable 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.

    Superior Construction. Manufactured from steel tubing for superior strength, this RTR Tactical Performance Adjustable Upper control arm features a one piece saddle style axle housing for additional rigidity and is completed in a durable gray powder coat finish for impressive good looks and long lasting corrosion resistance. 

    Forged Rod Ends. The forged rod end included with this adjustable RTR Tactical Performance Upper Control Arm is specifically engineered to house the patented MAX-C bushings which allows for maximum articulation, strength and durability of the bushing material.

    Max-C Bushings. MAX-C (Multi Axial Composite) bushings are made from a dual-durometer synthetic elastomer with a unique non-bonded bushing design that allows the inner reinforcement sleeve to redistribute loads throughout the cushion and bearing allowing for freedom of articulation while still reducing deflection for improved handling predictability.

    Grease Free Technology. The included Max-C bushings feature "Grease Free Technology" this is a process where a PTFE inner lining is bonded to the inner bore of the bushing during the casting process. The PTFE lining reduces friction, minimizes wear and eliminates noise. Because of this there is no need to lubricate the bushings during installation making these bushings grease and maintenance free.

    Application. This RTR Tactical Performance On-car Adjustable Rear Upper Control Arm is designed to fit all 2011-2014 Mustangs, including the V6, GT, BOSS and Shelby GT500 models perfectly. Sold individually.

        I currently have a BMR adjustable upper control arm and mount installed on my 2013 GT. If I switch to the RTR UCA, is it possible to use the BMR mount, or will I have to buy the RTR mount to install the UCA?

        • We have not experienced any fitment issues with the RTR Tactical Performance Adjustable Rear Upper Control Arm and the BMR Rear Upper Control Arm Mount.

        Do you need to buy the new mount for the RTR control arm or can you use the stock mount?

        • A replacement mount will be needed which can be found here:

        Does this come with a new cross bolt for chassis mount end?

        • A new cross bolt will not be included. This will reuse the stock bolts.

        Are these similar/comparable to the Whiteline upper control arm? I see those are not listed on this site any longer. They both look roughly the same in appearance along with the same type of bushing. I am using all Whiteline products for my rear suspension and wondering if these will fit in with the rest of my suspension.

        • These RTR control arms would be similar to the Whiteline control arms. While it would be different brand wise, the quality of the product would be relatively similar as well as the color matching your other Whiteline suspension parts.

        I currently have a BMR adjustable upper control arm and mount installed on my 2013 GT but there is a ton of noise from the polyurethane bushing. If I switch to the RTR UCA and mount will I experience the same noise?

        • The RTR Tactical Performance Adjustable Rear Upper Control Arm are designed to offer noise free operation from the Max-C bushings.

            Solid Part

            The RTR Upper Arm really connects the chassis to the axle. Far less lateral movement of the axle and a more planted feeling on hard acceleration. Adjustable feature allowed setting pinion angle to eliminate all vibrations, even at 7000 rpm!

            Must Have For Lowered Car

            Great upgrade for a lowered car. Helps get the pinion angle right. Also reduces wheel hope significantly. Pair this with adjustable LCA and you are set.

            ISeems well Built!

            Took awhile to assemble as I had to go easy on the threading together portion which was real tight but once broke through it threaded well by hand. I would have liked the L/H thread side to have been stamped as such but I noted which one it was. The stock GT500 Bushing is much larger than this one that made me think I should have got a spherical end instead since I paired this with the Upper mount as well as the BMR diff bushing set and set it at the stock length.

            Well designed part

            The Max-C joint is the star of this part... Easy upgrade paired with the replacement mounting bracket is a must. Only complaint is adjusting the pinion angle but with any part like this its going to be close quarters. I cut up a open ended wrench to make it easier. Overall a great part.

            No Instructions Included!

            I had to look up the instructions from another manufacturer to install this, there was 0 documentation available for this arm's install. Also, I had to get a jam nut for the top portion of the arm to prevent it from moving after install. The install process is very involved, I did it with hand tools, jack, and stands in a driveway. It took at least 6 hours, this is definitely a job that requires a hoist to be done efficiently. BUT, that being said the handling improvement is phenomenal! The car is much more tail happy, there is much more rotation available when you're at the limit and the axle seems to communicate much sooner when it gets upset on bumps. The sealed bushing is great, you won't have to crawl under and attempt to put a grease gun on it (access is extremely limited.). I would recommend this, but only if you get a proper shop to install it.

            Quality part

            I had a driveline vibration due to the lowering springs I added. I needed to get my pinion angle set correctly and this part fit the bill. It is a good solid replacement that also takes out the slop of the factory arm. The downside is a slight bit more vibration into the car. I can live with that given that this fixed my pinion angle vibration. The only reason this didn't get 5 stars is the size and the location of the flats on the center section. It is not easy to get a wrench that large over the center of the arm while its installed in the car.

            Pinion angle

            I initially bought this to adjust my pinion angle after dropping it. After installing it the retainer nuts have come loose twice. It is supposed to be adjustable on car but there is no way that is happening as you can't get under the car. Doesn't appear to have changed wheel hop but it has kept it in a straight line.

            Good fit, easily adjustable.

            I bought this and its bracket in fear of having pinion angle problems with a lowered car and installing a driveshaft guys one piece shaft, since there is only a 1/2 window on the shaft install.. Ran into no issue with that, but I kept the control arm on as it looks sharp and is much better quality than the stock part, that and if I ever do run into angle issues it is on there and the piece of mind is worth it.

            RTR GOODIES

            I installed this along with the RTR bracket when I lowered my mustang on spoetlines. Also have lower control arms and relocation brackets. Needless to say I hook much better off the line. Did a dig race against a pesky built vette and took him off the line until about 90 when his extra 150 horse took me.
