Review & Installation Video

Improves Traction And Handling. Replace your weak stock upper control arm with a Whiteline Performance adjustable rear upper control arm and mount for improved traction, quicker launches, and to eliminate "wheel hop" ensuring you're getting all your ponys to the pavement.

Adjustable. Unlike other aftermarket upper control arms, this Whiteline Performance arm is adjustable via the eccentric crush tube which allows for pinion angle and instant center adjustment without weakening the arm. This lets you precisely dial in your optimum settings to be sure you go straight down the track every time.

Synthetic Elastomer Bushing. This Whiteline Performance Adjustable Upper Control Arm uses a Synthetic Elastomer bushing that adds increased stability to the rear end without the harshness of commonly used bearing designs.

Superior Construction. Made from 4130 chromoly steel tubing for superior strength, this Whiteline Performance Upper Lower Control Arm features a longer arm length (which Ford incorporated in 2011) to reduce hop. Included is a heavy duty mounting bracket that adds increased rigidity to the arm.

Application. The Whiteline Performance Adjustable Rear Upper Control Arm with included Mounting Bracket is designed as a direct bolt-on upgrade for all 2005 to 2014 Mustangs including the V6, GT, Bullitt, and Shelby GT500 models.

    Lacks adjustment

    I'm lowered 2" on coilovers and have a 1-pcs driveshaft. I was trying to achieve 2* degree pinion angle difference but could not achieve it. I was only able get it to 1.5* which honestly is good as well but I noticed the eccentric bolt maxed out and only had limited range. Other than that I've had it for about 2 years now with no issues whatsoever.

    Solid feel!

    I got Ford to install this so they could set the pinion angle and so I didn't have to lay in my driveway messing about with the whole rear end, but it only took them an hour to install and set. When I got back in the car, I immediately felt the difference - the rear feels more solid when launching hard but is also noticeable on slow starts. I recommend you replace this if you do your lower control arms, as the stock upper one will take extra wear and stress. I go to the track a few times in the summer (road course), and I can't wait to abuse this part! :D

    Whiteline rear upper control arm

    I have added several Whiteline parts to my GT 500 and the difference in handling is incredible. Upper and lower control arms, lower control arm extensions, pan hard bar, pan hard bar brace, and Eibach front and rear sway bar. Much more stability in the back end and helps keep the rear from sliding out after shifting hard into second gear. You will have a harder ride due to the stiffer bushings. But worth the improvement in handling.

    Whiteline Makes Great Parts

    The Rear Upper control arm is a beautiful peice of hardware. dramatic improvement in traction and straight line takeoffs over stock. improved feeling of stability in the rear end under acceleration, turning and braking. all the whiteline parts are the best you can get in Race Engineering they look great and work as advertised. its the one with the blue suspension.

    Solid construction & fit, takes more effort than described to align

    The best feature about this part is probably the least explained in the instructions - how to use the eccentric hole for resetting the pinion angle. Once the stock part comes out - which is doable but took an impact wrench & patience, the axle tips forward so I was glad I researched elsewhere to note the stock angle before taking it apart. So to get the mount into the whiteline bracket takes an extra set of jack stands & a jack to pivot the nose back up so it reaches. The instructions gloss over this & how to use the eccentric to draw the nose back into line once they are together. OK, on to driving impressions. I was getting a healthy amount of chirp in the 2-3 high rpm senario as well as massive wheel hop just on loose snow & the part does as advertised. The back end doesn't scrabble around for traction. This part isn't a stand alone mod, tho - I added a stiffer sway bar to help with roll.

    Easy to adjust when installed

    I chose this upper arm as I am a tech at a ford dealership and have installed several aftermarket upper arms and have had issues adjusting the pinion angle after the part is installed.the white line arm is adjusted with an eccentric at the bushing rather than pinch nuts and a sleeve this eccentric set up is very easily accessed and adjusted.have another 2007 gt which will be getting this part installed in the near future.

    Excellent!

    The bushings in the Whiteline products are far superior to anything else out there. Install took some time because of the fuel tank. I installed these with Whiteline LCA's & LCA Relocate Brackets. These items are a must to improve handling of your S197. I would definitely recommend.

    It was very hard to installed since is a tight fit. But is well worth it. You can tell the difference in the take offs. It really puts the power to the pavement. I truly recommend this part if your looking for faster lunches.

    a lot of noise...

    I purchased this along with the J&M adjustable panhard bar and the J&M lower control arms for the rear. I gave it a low handling improvement only because I installed it the next day after installing just the lcas and adjustable panhard bar and only noticed a slight improvement in wheel hop which eliminated the last little bit of it. which is the reason for bang for my buck being average. Now, the excessive noise. the newer mustangs have the weakest drivetrains. I work at Ford and we have drive driveshafts, transmissions, and SOME gears being replaced along with the whole axle under warranty. now idk if they slam gears or not but I know mine had a little clunking from the lot. the bushings in the upper control arm from whiteline don't absorb Alot of noise so you hear every single turn of the ring and pinion. I can turn the radio up just a bit and have a normal conversation over it and I won't hear it. but it's there so just be aware that these stiffer bushings will let more noise come through even though whiteline claims they don't cause any unnecessary NVH.

    Not bad at all

    A very nice product. It's nice not having to get a mount separate for your UCA. The installation directions were very lacking, but it's easy to figure out with a Google search. To adjust the pinion angle, just loosen the jam nut and and tighten the bolt. Adjust as necessary, then tighten the jam nut. I used an angle finder app on my phone to get the angle I wanted.

    Worth the investment.

    I won't lie to you, this was not the easiest install on jack stands, but it is definitely worth the effort. Getting the old mount out and reinstalling the new mount was challenging because of tight work space under the car. The difference, however, is immediate and wheel hop is a thing of the past. The car feels much more confident and the rear end is solid. Some mild higher pitched NVH at certain speeds, but after driving for a week it has settled some and isn't significant. This piece and Whiteline's LCA's are worth every cent.

    Works good, but adjusting could be better

    The adj crush drive, in my opinion is not as good as the bmr style, had cortex racing install it, and they were not sure how to adjust it, and said it has to be pre set when you install it, wish I went with bmr on this one ... There is now a whining sound in some of 5th gear, and most of 6th, I like all the other whiteline parts, not sure on the u a though

    Launch with Confidence!

    Probably like every UCA installation, it was not an easy mod to install. In addition, the adjusting mechanism of the eccentricity was not the most intuitive. After contacting the guys at Whiteline, they were able to provide me great help with the adjustment portion of the install. Somehow everything made sense from then on, I was able to set the pinion angle and the amount of anti squat that I wanted. After installation, I took the car out to Autocross and I was impressed to say the least. Wheel hop is gone and the rear is Planted. This product took the performance to a different level. As a daily driver, I did notice increase in vibrations from both the road surface and my stock drive shaft. The decibels from the vibrations are tolerable. NVH is more noticeable at lower than higher speeds. To recap, Installation was worth it. I'm very satisfied with the product. I highly recommend it!

    Will fit convertible. It just takes longer to install. I had to remove braces to lower gas tank required for install. Not adjustable once on car, like other brands. But seem heaver and more rigid.
