Improves Traction. If your Mustang can't "hook up" you're going nowhere fast. That is why Whiteline Performance design these Adjustable Rear Lower Control Arms to improve traction, eliminate wheel hop, and as an added bonus decrease your 60ft. times.

Double Adjustable. Unlike other aftermarket control arms, Whiteline Performance arms are on car double adjustable so you can precisely dial in your optimum settings to be sure you go straight down the track every time.

Superior Construction. Made from 4130 chromoly steel tubing for superior strength and rigidity, these Whiteline Performance rear Lower Control Arms feature Synthetic Elastomer bushings with a non-bonded bushing design that allows the crush tubes to float freely, eliminating bushing wind and snap back, increasing handling predictability.

Application. This set of two Whiteline Performance Adjustable Rear Lower Control Arms are designed as a direct bolt-on upgrade for all 2005 to 2014 Mustangs, including the V6, GT, Bullitt, and Shelby GT500 models.

2 Top Rated Questions

Are these needed if I already have an adjustable Upper Control Arm? I have a 2012 GT that I am lowering and I know that I have to re-adjust the pinion angle as well. Question is do I need to use both adjustable lower control arms and upper ones? Is there a handling/performance difference between using the two? It seems redundant to use both.

  • The upper control arm is mainly used to set the pinion angle and reduce wheel hop. The lower control arms are not necessary if you are lowering your mustang, but they will be a great improvement over the flimsy stock pieces and will also further reduce wheel hop resulting in better 60ft times. Wether you decide to get the lower control arms or not, I would highly recommend getting a set of lower control arm relocation brackets. This will realign the lower control arms to the proper position after lowering your mustang. Without the relocation brackets your lower control arms will be pitched upwards which will actually lift the axle under hard acceleration.

Adjustments of the LCA I have an 08 stock GT. This will be my first mod as the stock bushings in the LH LCA is extensively worn and I did not buy this car to keep it stock. After some research and asking around i decided to go with Whitline. I have never really tinkered to the extent of adjusting the LCA's for improved handling and such though. Do they provide a "this adjustment gives this result" guide. Where is a good place to start with this. What suggestions do you guys have for the install. note: no relocation bracket yet

  • If the car isn't lowered, then I would start by adjusting them to the same length at the stock LCAs. I have not adjusted LCAs for handling either, I needed to correct my pinion angle after dropping the car about 2". Regardless, you should feel some improvement in handling and launches just by upgrading to aftermarket pieces. If I remember correctly, the correct pinion angle is about negative 2. You can ask the Google to learn more about pinion angles and how to measure it correctly. It's easier than it sounds, as long as you've got some room to move around under the car.

    Easy install. Squares up rear end!

    I bought these whiteline double adjustable lower control arms and relocation brackets, upper control arm and double adjustable panhard bar to compliment my Ford Racing K springs. I've tested many take offs and rolls on bumpy roads to test these whiteline products and I am quite satisfied with the improvement in handling. (Mickey street comps help) I have so much more control over the rear end. Did somebody say driftstang?

    Can tell the difference.

    Installed the control arms today in about 3 hours. One of the arms came a little shorter than factory, easily adjusted though. Only problem I had was that I did it on jack stands jacking up the back only, when I removed one side the jack stands shifted about a half inch making it difficult to get the new arm on. My suggestion, use a lift, or use four stands and raise the entire vehicle to the same height. Second gear about 4000 rpm and I get tire spin no matter what, these control arms make the wheelspin less severe, I think when I replace the upper it will make a real difference.

    Another Spectacular Product!

    I installed these whiteline control arms with the BMR relocation brackets because I am lowered. I like BMR brackets over the whiteline because there are three holes to choose proper angle instead of two. I felt that the whiteline brackets would be too aggressive for a street car. I am extremely satisfied with these control arms. No more wheel hop when shifting 1-2. Hooks perfectly and the adjustability is extremely easy. Whiteline does it again!

    Worth The Buy

    This is by far the best up grade to my mustang! With just these my wheel hop was significantly reduced. Don't hesitate to buy!

    WL Adjustable LCA's

    If you want to get all that power to the ground this is a very good place to start. After installing these I took it down the back road a few times at wide open and noticed less movement from the rear end as well as a quicker grip. Also ran these without AdvancTrac on and the only grip loss was from the stock tires. One quick note. Make sure you tighten the nuts down before you get on the road otherwise the sound does not sound so good. I must have knocked one during the install and it had come lose driving around the block and right turns sounded like they were binding up. Once locked down their was some VERY small noise increase when hitting pot holes. All around solid upgrade and a ton of fun. Install took me solo about 2 hours plus some adjustments I decided to make.

    These are the ones to get.

    These arms are great! Had some cheap arms on before, and these make the others look like children's toys. The bushings are top notch, and they are adjustable in case I want to lower my stang in the future.

    Better than stock

    I bought this item because I wanted to do a complete overhaul with the suspension. It was annoying having to listen to those stock bushing when they started squeaking horribly. I got these because the bushing were maintenance free- I don't have to grease them. I can adjust them, these control arms help with the wheel hop, and they increase my 60ft times. I also purchased the pan hard bar to go along with them. NOW ALL THE POWER IS DOWN TO THE GROUND!!!

    Night and day

    I got these to get rid of that annoying wheel hop while even driving into work. I got the adjustable ones for if I decide to lower later on. I wish I would have gotten these when I got my car instead of a few years later.

    Replaced my non-adjustable LCA's and fixed my pinion angle problem.

    I had non-adjustable LCA's on my car with a non-adjustable UCA with lowering springs and an aluminum driveshaft so needless to say, my pinion angle was off and I was getting a vibration at higher speeds. The only way to change it was to buy adjustable suspension components so that I could re-set the pinion angle. I bought an adjustable UCA to fix the pinion first, which it did, but when I took my car to the shop (a well known suspension shop) they noticed that my rear wheels were the tiniest bit off because the rear wasn't 100% perpendicular with the driveshaft. They recommended getting some adjustable LCA's and after a bunch of research I landed on the Whiteline LCA's because you can adjust them while they are on the car and they have bushings on both ends instead of heim joints which tend to be noisy. I probably could have saved myself some money/time by buying the LCA's to begin with but I decided to make everything adjustable. It's not a bad install at all, specially after I had just done the non-adjustable LCA's. It helps to have a friend with you to move the rear while you line up the LCA's but you could always do it yourself by adjusting the LCA's to meet up with your rear and adjust them once they're bolted in. They don't make any noise at all. No more wheel hop. The car feels well planted during a launch and they're... Adjustable! You bought a Mustang because it's a performance oriented car. Save yourself the time/headaches and get adjustable LCA's over the non-adjustable LCA's even if you don't need them now because you may regret it later on down the road. As always, American Muscle kills it with customer service and fast shipping!

    Good stuff

    Put these, WL LCA relo brackets, WL front and rear sway bars with endlinks, and the FRPP trans cooling scoop on my 2012 Boss 302 a few weeks ago. Huge difference in being able to get on it early out of a corner and in straight line traction. Instead of fishtailing, the wheels merely spin if I give it too much love, which is much more manageable and safer than what happened before. Get an alignment and/or check your wheelbase after the install to fine-tune the LCA lengths. A+ parts and service from AM.

    Cure to undesirable axle movement

    I bought these to cure the naturally occurring axle twist on my daily driven stock Non-Brembo 2011 GT. Even though I did not need the adjustability, I was drawn to try these for the Whiteline non-binding bushing design, bushing material durability and overall product finish. Acceleration feels much more controlled and linear. They came pre-adjusted to the stock length and install was a breeze.

    Excellent Product

    Installed with Whiteline Relo Brackets on a 2008 Bullitt. Definitely can notice a much firmer grip in the rear. The angle of the control arm is vastly improved with both products. Quality seems top notch. Noticed some more noise coming from the rear once in a while, I'm attributing it mostly to actually listening for it though.
