Steeda has the track-proven sway bars that will give you reduced body roll, adjustability, and the best handling of any sway bar out on the market.

Our press-fit welded billet ends are far stronger than stamping the end of the bar. Billet machining construction of the sway bar ends makes for far greater strength for a bulletproof sway bar.

Don't settle for sway bars that are not track-tested and made by companies who do not specialize in Mustangs. Steeda engineers, races, and wins with what it sells, order the best package for your daily-driven or track-driven 2015+ Mustang today!

Our sway bars have machined steel billet sway bar ends, whereas others on the market have coined ends. What does this mean? Our sway bar ends are machined out of billet steel round stock, in-house, on our multi-axis CNC lathes and go through hundreds of computer simulations to ensure the ultimate in strength and performance - this provides greater resistance to bending stresses, and has three major advantages:
  1. These parts are less prone to cracking/fatigue failure on the ends themselves.
  2. It also reduces unwanted deflection in the sway bar end. Excess deflection creates unwanted geometry changes, which physically changes your sway bar stiffness to a non-ideal rate.
  3. With less unwanted deflection, our bars will 'wear out' slower - any spring will eventually become softer over time as it is cycled through its life, our bars will maintain their designed rate for longer with less unwanted deflection.

Our bar rates are developed and optimized through advanced vehicle dynamic simulation and through extensive real-world testing. We engineered these bars to control the vehicles' roll stiffness properly while still allowing you to run softer springs. This optimizes your overall grip and balance of the vehicle while still allowing you to maintain exceptional ride quality.

Note: Front Sway bar will fit vehicles equipped with MagneRide Suspension but cannot be used at softest setting due to contact with factory ride height sensor.

CA Residents: Cancer and Reproductive Harm WARNING

Hi everybody Brian from here today to share with you our S550 1 3/8 inch Adjustable Front Sway Bar. Now, the front sway bar or anti-roll bar as alot of you call it and appropriately so. Does exactly that. It reduces body roll. And what I mean by body roll is as your going through a corner it starts to lean towards the outside and as you transition back to straight the car is now level again. So what these do is they flatten out the car. Which means better handling and better performance and just as important better predictability. The sway bar mounts or better yet connects at four points of the chassis. At the outer most points, utilize the factory end links or our adjustable end links. Which then connect to the factory struts or again our struts. They also mount to these D brackets that are mounted and bolted to the chassis. So the way this works is if you're going straight down the road and one of the beauties of adding sway bars is they don't change the ride quality of the car. Is that your driving straight down the road, these will just pivot up and down with your suspension. Because you're not throwing the car in a roll situation where it's maybe trying to lean. As your driving down the highway it's nice and smooth. Now when you get into a situation where you're having more fun with the car, testing out the suspension or those new tires you just put on. As you get into a corner it's going to want to lean. Like this, or like this. And the idea is when this side wants to compress, it's going to push against this side. The D brackets are going to remain the same. So the stiffer, you can in essence, make the sway bar the more roll resistance it's going to have. The flatter the chassis is going to stay and the flatter the car is going to stay in the corners. This means higher speeds, better predictability and more control overall. Since we know everybody's use is different, suspension setups are different, driving styles are different and whether or not you're matching it with the rear sway bar, The sway bars and anti-roll bars are a great way to really tune the handling of your car. If your auto-crossing, going to track days or just carving canyons. The front sway bar has four settings. If you go to the softest setting or the setting farthest towards the outside of the arms, that's going to be about 42% stiffer than the factory performance pack sway bar. If you come into the stiffest setting, it's going to be 97% stiffer than the performance packed sway bars. That means better roll resistance, which equates to faster lap times, more autocross wins and a better handling car. Speaking of strength, we take things on step farther. We perimeter weld around the sway bar at the ends. This makes it extremely strong. In addition, we have integrated centering collars that will keep the sway bars centered under the car, no matter what kind of corners you throw at it. We finish off by powder coating the sway bar for corrosion resistance. In addition, the sway bar brackets are also coated. All the necessary mounting hardware is provided and our sway bars are covered by our lifetime warranty. We proudly manufacture these sway bars in the USA at our Valdosta, Georga facility.

car should drive like this out of the factory!
I spend Sunday installing Steeda's front and rear sway bars (with billet aluminum sway bar bushings) on my 2015 GT PP. This is in addition to the progressive springs and sub frame bushing supports that are already installed. The installation of the rear parts were easy while the front was more tedious but not impossible for the average mechanically inclined person. I opted for maximum stiffness on the sway bars for the best handling performance. visibly there is a huge difference in the side and quality of the sway bars. Steeda's are much more stout and the bushing are significantly stiffer, the mounts are lighter (based on the standard mounts that come with the sway bars) but a much better design. The sub frame braces look like the perfect way to tie the IRS sub frame into the vehicle and tighten things up. The brace connects near the jack points on each side to two points on the sub frame and one point in between creating a triangle for some serious stability. This is a tight fit so make sure you follow the instructions from Steeda and keep the bolts loose until things are set. I haven't had the car on the track yet, but there is a huge difference in just daily driving. I've hit a couple of curves hard and the car seems to dive into them and there is much more confidence in the car. I hit a pretty sharp curve the last 2 days on my way to work and I don't feel any understeer at all (at least I can't tell) I was doing between 60-70 mph through the turn it just felt nice! All in all I made a great choice. Steeda should have sold these to ford during manufacturing and the car should drive like this out of the factory!

The car feels very nimble and netural
Ok so after a couple days of driving and finally getting some spirited driving in today I think the sway bars made a significant improvement in handling. The car feels very nimble and neutral compared to before. I went with the middle hole in the rear and the 2nd stiffest setting up front. Would recommend this to anyone looking to feel more contacted to the car in the corners.

One of the biggest improvements to the handling of the car
One of the biggest improvements to the handling of the car is definitely the Steeda goodies all thanks to David here on the forum. He helped me so much picking out everything I should upgrade for all of the suspension parts to make this a great daily driver but also be able to take turns comfortably at high speeds and put the power to the ground. One of the first Steeda upgrades Slammered threw on for me was the Front/Rear Sway Bars and the IRS Support Brace and damn did it make a pretty damn noticeable difference in turning. No I don't track this car as of right now but the closest I get to taking turns and curves is off ramps from the highways and I've done decent speeds coming through those turns. The sway bars help keep the car planted and definitely boost the handling capability that the IRS already provides. I also installed the billet mounts and they look damn good with the blue sway bars and definitely are top notch quality over the stock mounts from Ford. Wheel hop has been one of the most notorious things the S550 platform has encountered with the new IRS system. Wheel hop is a No no and Steeda's IRS bushings are definitely the first step to knock out way more than 50% of the notorious wheel hop. When taking the bushing out of the box and taking a peek at my new goodies, I was amazed of the quality that is put into the manufacturing of the parts Steeda offers. IRS Bushing from Steeda is a must if you're looking to eliminate more the 50% of the wheel hop. It's great quality and definitely helps put the power to ground. When hitting it and shifting from 2nd to 3rd it's a whole new feel and it just takes off.

It's a Huge difference from the relatively vague/floaty stock PP setup
The G-Trac brace made a big difference in ability to turn in with exactitude on my PP-equipped GT, albeit modified with Steeda springs and sways. The back end of my car got where I needed it with Steeda springs, sways, bushing mounts and vertical links. The car now steers beautifully, doesn't roll, doesn't pitch on acceleration or dive under braking, and the front-to-rear grip is matched, yielding great confidence to place the car right where you want it on corner entry, mid turn, and exit. The G-Trac brace's effect on steering was both noticeable and transformative. It's a HUGE difference from the relatively vague/floaty stock PP setup. I'd say it even rides better without those stock PP undulations. I did not feel the need for the rear brace after the bushing mounts and vertical links (put on after everything else), but that's not to say that the chassis wouldn't improve yet more from it; I'm still considering doing it. It's just that the car feels perfect right now for hard-ass canyon carving and everyday use.

Car feels like a go kart now
Car feels like a go kart now compared to the body roll OEM had. The Steeda sway are freaking awesome

The ride is amazing, to be honest
The car sits perfect with these springs. The ride is amazing, to be honest. The nose dive on braking has been reduced great,y. The car is very flat when cornering and just begs to be pushed more and more. One thing that seems to have greatly improved is the response of the initial turn in. It is very, very responsive. I assume it's a combo of the springs and sway bars but not sure which contributes more to it? I set the front sway bar on the 3rd setting, one away from the firmest and the rear one is set on 2, one away from the firmest.

I'm officially a believer!
Ok. So I know everyone has already made threads about their Steeda stuff, but I'm officially a believer! Springs Sway bars Sway bar Billet Brackets Vertical Links Toe Arms Bump steer kit G-Track Brace IRS bushings MMR Camber Plates Performance wheel alignment The car is a go kart. Set the front sway bars to the center and rear to the lower settings, entry high speed turn is predictible, so much so I haven't learned the limits yet. The ass can be easily manuvered with throttle (Race mode/traction off). The body roll seems like it's gone (once the track wheels/tires come in I'll know for sure), it's unreal, I am in LOVE with the car now. This is the way it should've come from the factory for the PP cars. Really a learning curve, since now everything is souch more compossed. The IRS bushings and arms drastically changed the feel of the car on take off, the power actually goes to the tires (which I spin even easier now, even with camber still within factory specs.) There's not that feeling like the IRS wasn't properly fastened, it feels like it's built in to the body. Such a great mod. I'm ordering the IRS brackets as well, but I don't see how it can really improve further. It that good!! Steeda has my vote!
