Review & Installation Video

Stephanie with AmericanMuscle.com and this is my complete breakdown of Whiteline's Adjustable Rear Upper Control Arms. As well as, a few different lower control options that will help you and your 2005 to 2014 Mustang. For those of you that do not know, Whiteline has a worldwide reputation as a leading manufacturer of suspension components that provide innovative solutions to suspension and handling constraints. Whiteline's products are known to deliver proven performance and provide significant gains in vehicle balance, steering precision, and grip level. Taking a look at some of the main suspension components we have here today, we all know that the upper control arm is very important when it comes to traction and handling performance. And also when it comes to being able to adjust your instant center and pinion angle, especially for those of you out there with lowered Mustang's and one piece drive shafts. Whiteline offers this adjustable rear upper control arm with the mount that will provide improved traction, allow for faster launches, and eliminate that dreaded wheel hop through a longer-than-factory arm length. This upper control arm is adjustable through this crush tube which is what's going to allow you to change your pinion angle and instant center adjustment, all without weakening the arm. This feature is what's going to allow you to dial in your Mustang's optimum settings for the best performance possible. And lastly, the adjustable upper control arm features a synthetic elastomer bushing that adds increased stability to the rear but without the harshness that we would normally see with the commonly used bearing designs. Whiteline currently offers three different types of rear lower control arms that will ultimately work with the upper control arms to offer even better performance. Two of these options, the fixed lower control arms and the standard adjustable control arms, are made from steel tubing for strength and stability, and feature synthetic Dual-Durometer Elastomer Max-C bushings with a multi axial composite design. As far as the Max-C bushings, the Dual-Durometer compound of the lower control arms helps dampen NVH. The reinforcement sleeve inside redistributes load to prevent binding or gapping and the PTFE Liner serves as a lubricating agent for a grease-free, silent operation. The fixed lower control arms feature forged ends, while the single adjustable lowers offer an on-car singular pinch-fold adjustment so you can dial in your settings as with the adjustable upper control arms. Our third option from Whiteline here are the Double-Adjustable Rear Lower Control Arms. These are made from tubular chromoly steel and have a non-bonded bushing design with a synthetic elastomer bushing that will allow the crush tubes to float freely. This eliminates bushing wind and snap-back, leaving you with increased handling predictability. As the name implies, the only other difference here is the dual on-car adjust-ability. Your choice here with the lower control arms, really depends on your current or planned setup and what you want to do with your Mustang. Either way, Whiteline has you covered. All of these options are relatively easy to install and if you look at them individually, you're looking at about an hour for the install with a bit more time needed for fine-tuning the adjustable options. And, of course, make sure you have your jack and jack stands ready. As always, be sure to reach out to a Mustang expert by phone or email if you have any questions regarding which option would be best for your build or even if you just have an install question. So if you want to improve your traction off the line, reduce wheel hop, and have the ability to adjust pinion angle, then you have to check out these options from Whiteline. Available right here from AmericanMuscle.com

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.

Will this work for a car with a 2" drop in the rear ?

  • Unfortunately this will not work with a 2 inch drop in the rear. We recommend traditional adjustable control arms for bigger drops.

Helpful (0)

Will this control arm be sufficient with my car being lowered 1.5 inches

  • This Whiteline Adjustable Rear Upper Control Arm will work perfect with your vehicle especially since the vehicle is lowered. The adjustability will help perfectly dial in the set-up.

Helpful (0)

My car is lowered 2" is there enough adjustment in this control arm to reach the correct pinion angle. Thanks

  • The Whiteline Adjustable Rear Upper Control Arm w/ Mount will have a more limited adjustment range than traditional adjustable control arms, and will most likely not accommodate 2" of lowering in the rear. We would recommend a traditional adjustable style for this application.

Helpful (0)

If I have no plans to lower my car, would it be better to use this UCA or a non-adjustable one. Thanks,

  • The adjustability gives you the freedom to set the car up to your prefered handling however if you are not running this car on the track and at stock ride height, I would suggest the non-adjustable control arms.

    Great Upper Control Arm

    Definitely gives my mustang a more planted feel and it has a lot less squat on acceleration along with my whiteline lower arms.

    Upper control arm

    Very well built upper control arm. It fixed my pinion angle and you can definitely tell a difference the rear is way more stiff on launches.

    Great trusted name and quality piece

    My only complaint it the eccentric bushing doesn’t have a lot of adjustment due to its design. I was able to get the correct pinion angle reguardless, just saying you don’t have the same amount of adjustment as a threaded screw.

    hook and book

    Wish it came with some better instructions on how to per set the arm length. Only complaint is that is created a fare bit of noise and tunnel vibration to the car. But glad to have done the upgrade, car now lunches better and improved rear traction.

    Beefy upgrade

    When I first unpacked the upper control arm I was impressed with how beefy it was and the perfect weld beads, my second thought was "how could the wimpy factory pieces even keep the rear off the ground? Relatively easy install (I have a hoist) my only advice is remember to step the torque of the bolt - as in go to 80 lbs ft, then 100, then 129. Same with the bolt under the back seat. Wheel hop? Gone! Tracking is perfect, I thought my car put the power down out of the corners well before, now it is surprisingly good.

    Whiteline Adjustable UCA

    I installed this a couple of months back, and let me tell you that this piece combined with the LCA's is just amazing. it eliminated completely the wheel hop and the real axle feels solid. I can launch with confidence now, its just beautiful. highly recommend this.

    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.

    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.

    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

    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

    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.

    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.
