- How to Install a Whiteline Adjustable Rear Upper Control Arm on you 2005 to 2013 Mustang
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.

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.Helpful (7)

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.Helpful (8)

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.Helpful (9)

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.Helpful (10)

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.Helpful (10)
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.
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.
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.
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.
