      Review & Installation Video

      The Eibach Adjustable Anti-Roll Front and Rear Sway Bars are a great choice for your '11 to '14 Mustang, because they reduce body roll for a seriously upgraded handling performance, much flatter cornering, and, honestly, just a sportier overall feel. This particular set is three-way adjustable, allowing you to fine-tune exactly how you want the front and exactly how you want the rear to perform. The installation isn't too hard, so I'm giving this one out of three wrenches on our difficulty meter, which I'll walk you through later on. If you're not too familiar with how a sway bar works, in a nutshell, it's basically controlling the side-to-side movement of your Mustang and really comes into place around tight corners. Their main function is to help reduce body roll and maintain stability rotating through a turn or even just changing lanes. The factory sway bars are pretty neutral. The stock front bar is 34 millimeters in diameter, and the rear is 20 millimeters in diameter on the '11 to '14 GTs. The GT500s have the same front, but a slightly bigger 24-millimeter rear bar. The V6 gets the biggest change from a 28-millimeter front bar and especially because they didn't come with a rear one from the factory. Picking up a larger rear bar like this one will tighten things up to promote oversteer, which is basically the rear end rotating through the turn. A larger front bar will promote understeer, which is basically the car just plowing through the turn or losing grip while overturning, causing it to go straight. So your goal with this is to typically find a happy medium between the two, so picking up a full kit like this will really improve your over/understeer balance. They're also called anti-roll bars for a reason. They'll keep your ride flatter through the turn, which is great for track use or just daily driving since it's noticeable even with that quick lane change I mentioned. They make such a big impact, because they're noticeably larger in diameter than the stock size, as I just mentioned. The Eibach front bar is 36 millimeters in diameter, and the rear is 25 millimeters. This will offer one of the biggest size increases in the category. The bigger the bar, the more of an impact the anti-roll characteristics will have. The fact that it's adjustable will make them even more impactful and help you to fine-tune what you like the most. Now, as you can see, at the end of each sway bar, there are three open holes in the arms, which allow you to either go to the stiffest, softest, or a more neutral feel. Whether or not you want more oversteer or understeer is completely personal of a preference, because each driver is different. Using one of the stiffer adjustments on your bar will keep your S197 a little flatter through the turn for a tighter suspension, and the opposite is true for the outer adjustment hole. The bars are even a higher quality build, too. Expect both to be made from a high-quality steel alloy, solid cold-formed, tempered and short-pinned for strength and durability as needed when under so much suspension flex and pressure. It's all made right here in the USA. Now, the red powder-coated finish does give it a sportier look, but it, more importantly, helps with long-lasting corrosion resistance, and it's honestly just a red Eibach classic. Now, the kit includes a set of greaseable polyurethane bushings for responsiveness, which are perfect for a street or a track car since they are more rigid than the factory rubber bushings. This means they'll take it even a step further to prevent movement, keeping the suspension even tighter. The kit has precision-forged ends and OEM-style pressed bushing locators as well with no weak points. This complete kit comes in just south of the $600 mark, which, in my opinion, is a well worth it price for something that impacts your suspension so much and can really improve your driving experience. Obviously, if you're not too interested in an adjustable option and just want a quick replacement, you can save a few bucks by going with a non-adjustable, more entry-level option. But if you want a more preferential experience with a race-inspired kit, this one will definitely come in handy. Now, the installation itself gets one out of three wrenches on our difficulty meter and should take about an hour or two in the garage or shop. If you've never swapped out a sway bar before, just know that it doesn't require too much mechanical experience, just a few simple hand tools, like a ratchet, and socket set, and a jack and jack stands, or a lift if you have access to one. Once the car is in the air, you start in the rear by removing the 10-millimeter bolts holding the brake line bracket to the sway bar end link bracket. Next, the bolts holding the sway bar end link to the sway bar come off, then the bolts holding the bracket to the frame. Install the new poly bushings over the sway bar, then slide the brackets over the bushings. You can install the Eibach rear bar to the factory locations using the same bolts, and this is where you can choose your adjustment point. The hole closest to the rear of the car will soften the feel. The hole closest to the front of the car will tighten it up. The fronts are essentially the same process. You'll disconnect the end links from the bracket, remove the front sway bar, swap it out, and replace the bolts to the adjustment setting of your choice. I would personally recommend starting off in the middle hole here, which is the neutral setting, just to see how it feels in the neutral position on the road. And then from there, if you want it tighter, you can adjust that way, or softer, you can adjust the opposite way. Well, that just about wraps this one up. So if you're the owner of an '11 to '14 Mustang, you might wanna check out the Eibach Adjustable Anti-Roll Front and Rear Sway Bars, which, of course, you can find right here at

        Didnt get expected results

        Didn’t really notice much difference with these over the stock 2013 GT sway bars if im being completely honest. Also, by the time I purchased all the parts and labor to change these out I ended up spending over $1000. Definitely NOT worth the money in my opinion.

        Body roll gone

        Only driven it once since I installed so it's still to early to tell however I did notice that the body roll is no more. Took a little over 2 hours to do on jack stands. Front took a little longer because I had to remove a frame that was in the way from the sway bar from coming out. Other than that everything fit perfectly and did not take long at all.

        Eibach Adjustable Anti-Roll Sway Bars

        These sway bars made such a difference in the way my 2014 GT feels and handles! I had never been in a vehicle before and after installing aftermarket roll bars before, so my thoughts going into it were, 'Maybe you can tell the difference in hard corners or really throwing the car side to side.' It took an afternoon to get these installed in my garage by myself and I decided to set them on the stiffest position. As soon as I opened the door and sat down I could tell that it was significantly different. There was no wobble side to side whatsoever. I can take turns and round-a-bouts in my area fast enough to cause the car to slide sideways and it does so flat as a pancake. The body roll is virtually eliminated with these sway bars and it feels so sporty! The only thing I am disappointed by is the fact that I waited almost two years to buy these. I would highly recommend them!

        Eibach Sway Bars

        Easy to install, i took my time to install it just to be sure. You can really feel the difference in the curves on the middle setting. The only down with the kit it's the skweeky noise you can hear at low speed, but that is normal with polyeurathane bushings.

        Eibach adjustable sway bars

        I put eibach sport line springs and it lowered the car 1.35 in. In the front and 2.0 in. in the rear i had oversteer this corrected the problem. I also run the sportline shocks and struts this all is a very good combination.

        front is good, rear is badly designed

        nothing to say about the front, put it on and forget. The rear though... 1) on a 2012 v6, on the hardest setting the sway bar does not quite clear the suspension. It fits but it will knock on the driver side, taking off paint from the bar. So you're forced to either live with a knock or set it to soft 2) it's poly bushings so it needs grease, but it's not on-the-car grease-able. There are no ports. You'll get really proficient at taking it off and putting it on again. 3) the biggest bushings - between the bar and the links - press out grease in under two weeks. I don't race, it's a daily driver, but in two weeks (of no rain and no car wash) the rear squeals again. Mobile 1 synthetic or Royal Purple - doesn't matter. 4) same point, is held together with 2 miniature hex bolts each side. Not tighten enough - they come out. Over-tighten and you'll strip them. The spot naturally gets dirty, and the hex heads get packed full of dirt. Make sure to get it all out before you put the driver in, or, you guessed, you'll strip the heads. Overall, a royal pain in the rear, literally and figuratively.

        Mind Blowing performance!

        I questioned myself when I chose the look of a '14 GT vs the track performance of the '15 GT. Not anymore!! These bars combined with sportline springs and Eibach shocks and struts are beyond next level...!

      Do you need to buy separate end links with these?

      I received my kit and the sop installed the front but said the hardware was missing for the back bar, is there a way to get this without the shop needing to remove the front bar again?

      Hi guys! So I have the EIBACH ADJUSTABLE ANTI-ROLL FRONT REAR SWAY BARS for my 2014 GT. Somehow one of the bushings on the front sway bar tore and I have no idea where to get a replacement.

      • We are sorry to hear that you the bushing is no longer in usable condition. Unfortunately we do not carry these replacements bushings, however, this is something that may be acquired through Eibach directly.

      Do I need new shocks and springs with this kit? Hi everyone, I'm still running all stock suspension on my '12 V6 (I put on the strut tower brace) and my bushings on the rear sway bar are giving out (50k KM) so I'm considering upgrading the whole set anyway for better handling. Will I need new shocks and springs with this? Also, how much life can I expect from the new urethane bushings? Thanks!

      • Can't speak to bushing life, sorry. But you do not need new shocks and struts with this kit. That said, if your sway bar bushings are worn out one might want to look at other suspension components for excess wear.
