    Features & Details

    • More Traction, Quick Launches, Less Wheel Hop

    • Exclusive 3-Part Bushing

    Dial-in Traction. Whether you're setting up your suspension for the strip, the street, or a road course, Steeda's Adjustable Street Upper Control Arm will eliminate wheel hop and ensure you're putting power down to the ground. Unlike "one size fits all" arms, this adjustable upper control arm will allow you to adjust your driveshaft-to-differential pinion angle and optimize your suspension geometry for maximum traction and smoking fast launches.

    On-Car Double Adjustable. It's easy to dial in your settings with this arm. Since it's adjustable on both sides, you can make changes right on the car, without having to remove the arm to get things set up right. That makes changes quick, easy, and straightforward - just like it should be.

    Better Handling. With Steeda's exclusive, race-proven 3 piece bushing kit on the axle end, this upper control arm reduces axle wind up and wheel hop and allows proper articulation without deflection - resulting in improved handling, better cornering, and greater overall stability.

    Race-Tested Performance. With a race version widely used on NHRA and IHRA winners, this street & strip arm feature a softer outer bushing to prevent binding and increase grip on uneven surfaces.

    Application. The Steeda adjustable street upper control arm is designed for 2011 to 2014 Mustangs including the V6, GT, BOSS and Shelby GT500 models.

    Adjustable or non-adjustable UCA's for '14 Mustang GT with stock springs? Is it advisable to use adjustable UCA;s for '14 Mustang GT with stock springs? If so, what are the advantages?

    • Adjustable UCAs and LCAs give you the advantage of adjustment of the pinion angle, especially for lowered cars. If the car is not lowered, an aftermarket UCA will be stronger than the OEM UCA. If you decide to change the pinion angle for whatever reason, the adjustable UCA/LCA will allow you to do that. But with a stock ride-height, the main advantage would be strength and stiffness. Also, remember that the Mustang has a CV on the driveshaft, which corrects for minor amounts of pinion angle. Good luck.

    necessary for lowering? When lowering your car, is purchasing this part 100% necessary to avoid damage to the differential?

    • It is not mandatory, but an adjustable upper control arm will allow you to set the correct pinion angle (normally 2.5 -3.5 degrees). When lowering the car, it is essential to check your side to side differential centering to ensure your body to rear wheel clearance is the same on both sides of the automobile. Centering the rear diff in reference to the body is easily accomplished with an adjustable Panhard bar. Good luck.

      Control for not a lot of money.

      Installed this along with a set of whiteline lowers. Even for a V6, the car was squirrley on hard launches. Not any more! Car hooks up much better and is far more stable in every aspect of driving. Well worth the investment. Oh, and it really doesn't transmit much NVH at all. Barely noticeable!

      The adjustable upper paired with the steeda non adjustable lowers really helped eliminate wheel hope. Stiffened up the feel a little bit but still rides nice.

      Steeda Adjustable

      This item went in with ease. I have not had any launch yet as one of my UCA support bolts broke off when installing, not the products fault. Very easy to adjust and tighten up.

      This is one the first things you should buy if you are going to mode your mustang it keeps the axel/wheels on the ground also it gets ride of that annoying wheel hop I prefer this over stock but make sure if you get this you also add the upper control arm mount or you will get a very loud knocking sound when you drive.

      Great for a lowered mustang

      I think this is an amazing buy if you have a lowered mustang it's a must because you need to fix your pinion angle! Don't wanna mess up those u joints. Very easy to install not a problem definitely recommend getting a aftermarket mount with it so it fits better and you can toss those old skimpy factory parts.

      Wheel Hop Gone.....

      So all I can say forsure is this product is of great quality and fit great. Took about 1 hour to install on a lift. Had to remove lower rear seats. I have a 2011 mustang gt 6spd stick and wheel hop was crazzy ! Now... wheel hop is 200 gone. But is it due to this UCA ? Maybe.... but at the Same time I installed a Whiteline Lca's and an adj. Panhard bar. So I can say with this trio of mods installed all at once the wheel hop is 200 gone. Also there is some slight-moderate vibrations coming from the rear. Ive been told its the UCA. In my opinion though Id rather have some vibrations rather than wheel hop. When I launch this car now and bang gears... it just has traction and pulls!

      If you go with this get the mount as well!

      I bought this and installed it with the stock mount. Needless to say it didnt last very long. I got the clunking noise right away which is due to using the stock mount. The bushings are also not as beefy as the BMR ones. Long story short the adjustable LCA is a pain to install and after going with the BMR upper control arm and mount side by side you can see the quality difference. No issues so far with the BMR one so far. If you do decide to stick with the Steeda adjustable make sure you get the upgraded mount as well otherwise it wont last long. Install on the adjustable is also a ton harder compared to the non adjustable.

      very good

      helps plant my car down. **tips....make sure you know where your driveshaft is before so when you put back on you can put back correctly. also make sure you take the correct measures before installing. it is simple to unbolt and rebolt. the hardest one is going to be located under your seat. pop your back seat out and BOOM big bolt right in middle. (i had to use a breaker wrench to loosen that one up!)

      Great piece in a small package!

      Adding this UCA really helped finish up my rear suspension. I had pretty much eliminated wheel hop with the Steeda LCA's, this piece really helped me dial in the rear and put the power to the tires. I as having issues keeping the car planted in second and third when the motor wound up. Once I got the rear end pinion angle right, had a much easier time planting the wheels!

      Great improvement

      I installed this control arm and set the pinion adjustment in about an hour and a half. I was lucky enough to get to use a lift at my work. I tried doing it on jack stands but couldn't seem to get enough room. It's a great quality piece. The rear end feels much more solid. It took the slop out of the turns and launches. There is more NVH but not bad. I can hear the pinion spinning once I get up around 70 or so. The handling improvement far outweighs the small noise increase. It's a solid, great quality part.

      Small price to pay

      If you lower your car an Adjustable Upper Control Arm is going to be necessary. You will also need an adjustable Panhard bar. After I lowered my car I experienced severe wheel how under full acceleration in second gear. It was as if my rear wheels could not make full contact and just skimmed the road. The Steeda UCA solved that problem. When I hit the gas in any gear I get full contact. I also changed the gears to 3.73, the LCA's, Panhard and Axel backs. The rear end of the car is firm and planted and gets as much traction as the Pirelli rubber will allow. BUT, there is a price to pay. With all those rubber busings from the stock parts being replaced with much harder busings I do get more noise. All kinds of noise from a slight gear whine to occasional linkage clunks to even the sound of the weels turning. I don't think it is very noticable as no one who has ridden in my car has noticed it. I notice it because it's my car and I know how it sounds. My car is a convertible so it is not as insulated as a coupe so that may be part of the issue. Just know that you may experience some noise and you won't be disappointed. The performance and better appearance make it all worth while.

      Should be factory installed

      Really tightened up the suspension! Power is transmitted much more efficiently. The hardest part of the install was rounding up the tools and getting enough leverage lying on the garage floor with a torque wrench! You do tend to hear the drive train a little more (diff, driveshaft play when shifting gears), but it's very manner, and the benefits far out way the noise.

      Steeda UCA is well made.

      ...but not exactly easy to adjust. The nuts are big and beefy necessitating a large wrench but the working area is pretty tight. I assisted my mechanic buddy with the install. I added this piece, Steeda's strut mounts, and Shelby LCA's to the FRPAA suspension kit so it's a little hard to isolate the Steeda part's performance by itself. The car corners and launches well, but still hops sideways cornering over bumps. Not crazy about the adjustable Tokico D Specs that came with the kit, but that's a review for another day.

      Because race car

      If you've lowered your car and you need to adjust your pinion angle, this is the way to do it. Don't be cheap and buy just the arm. do a mount as well. NVH is increased so be ready for that.

      This is a good part to get if you wanna finish tightening up your rear end. LCA replacement is only half the battle just go ahead and do it all you wont regret it. Even after my lca replacement my rear felt a little sloppy...not any more feels real tight and compliments all other rear end mods well. Traction seems to be improved, must have if your are lowering your car

      OK product

      It installs easy enough and it eliminated the wheel hoop. But what is not told to the public is that it allows every clunk made by the driveshaft to travel through the Upper Control Arm into the cabin. For anyone doing this upgrade save up enough money to buy a one price driveshaft or else you will listen to a lot of driveshaft noise.
