      Review & Installation Video

      Hi I’m Justin with, and I’m taking a closer look at Whiteline’s heavy duty 33mm adjustable front and 27mm rear sway bars fitting all 2005 and newer Mustangs. Whiteline is a company that focuses solely on quality suspension components for a wide variety of vehicles, they’ve recently entered the Mustang world and the early reviews have been very favorable thanks to their well built and innovative products. Alright, first things first, if you didn’t know by now, a set of aftermarket sway bars is going to be the best way to achieve better handling and improved grip by reducing your body roll and understeer while cornering. Whiteline has come through with a very solid product here, and these sway bars are loaded with features that other sway bars do not offer. For one, both front and rear sway bars are constructed using 100% solid spring steel, for added strength. Now, a lot of other aftermarket sway bar companies opt to go with a hollow sway bar, for cost and weight savings, which isn’t necessarily a bad thing, but that solid sway bar is going to be inherently stiffer than its hollow counterpart. Secondly both front and rear sway bars are 4 way adjustable, this is going to give you a little more fine tuning ability versus other sway bar options, in addition both sway bars do come with very nice adjustable end links, and these lateral locks. The job of these lateral locks is to prevent any side to side movement of the sway bars, to help the overall effectiveness of the sway bar and to keep any stress off those end links. Finally, whiteline claims that their bushings are unlike any available on the market today, instead of using a high performance polyurethane bushing like many other suspension companies, Whiteline uses a synthetic elastomer material for all of their bushings. They claim that these bushings do not produce any noise, do not transfer any extra vibrations, and best of all they are absolutely zero maintenance meaning you’ll never have to grease them. Install time for each sway bar should only run you about an hour apiece, keep in mind though you will be working underneath the car so just make sure you have your jack stands ready, along with your basic hand tools and sockets. So if you’re in the market for a set of aftermarket sway bars for your 2005 and up Mustang, then you’ll definitely want to look into these quality products from Whiteline available right here at

        dont see any difference and no instruction.

        I couldnt feel any difference on my 06 mustang gt. it didnt come with instructions as to how much torque for the Axle brackets and endlinks bolts. oh... two the of the nuts stripped on the Axle brackets. I didny bother to call AM instead i weny to local hardware to get two nuts. If you are on the market for an after market swaybar, please look for another brand.

        Good Value!

        Had the dreaded factory sway clunk at 47,000 so tried this out. Easy install and looks nice. Pleased with corners and absolutely no sound or clunks. Second to stiffest setting seems just a tad more aggressive than stock - perfect!

        Quick and easy install

        Install took just under a hour with basic tools and no lift. Definitely feel the difference in the handling. Still playing around the the adjustments but seems to be dialed in pretty well.

        5 2014 GT - Averagedude Installation Time: Less than 1 Hour

        Big upgrade for the price

        My stock rear sway bar was clunking so I figured I'd upgrade. My 14 GT has Ford Performance springs and shocks on all four corners. I've only driven it about 50 miles but there was a huge difference in handling. The back end is really planted now. Took a traffic circle at *ahem* speed and now I know the front needs help because clearly the rear is way outperforming the front suspension. Highly recommend this kit. Install was easy. Remove the old sway bar, put the endlinks on with the big spacer on the inside and washers on both sides outside the stock bracket. Put the endlinks onto the sway bar, the get the U Bolt, nuts and bracket ready. Swing the bar up, throw a U bolt over the axel and install the bushings and bracket. Tighten it all up, put the wheels on and go. I used the second to the lowest hole on the endlinks and have about 1/4" of threads showing on the adjustable part. Sounds tough and the instructions suck but it's not bad at all. Just get the rear up high and use jack stands.

        Suspension Mods

        This is much bigger than the factory sway bar easy to install and helps with the whole suspension mods I have done to my GT.

        Instructions are next to useless, though it is an intuitive install. Was looking forward to feeling the difference but honestly nothing noticeable over stock. Would look elsewhere for a sway bar.

        GREAT BUY

        2011 V6. Have this paired with Steeda front adjustable sway and Strange adjustable shocks/struts. All on "half" setting. Car rides on rails. Absolutely no kick out from rear. Easy install-I did mine at night, in the rain.

        Easy to install

        Arrived quickly. Installed easily. The clunking from the factory rear sway bar has been eliminated. It would have gotten five stars from me if supplied torque specs were for the U-bolts were correct; both had to be replaced due to the threads stripping. Would like to have had more info on making the most of the adjustable links, too. Tech support at American Muscle was helpful. I'm looking forward to upgrading more suspension parts and tires to take advantage of my new sway bar.

        Close to perfect

        I went to Whiteline after experiencing bump stop noise and general clanks and squeaks from my FRP equipped stock 2013 GT350. Noise is still there, but only on cold days. I don't need to lube, which is nice. The rear stays planted, even under my untrained right foot stomps. No noticable skidpad loss, still under uber control in the corners. Flat stance and control at 1g laterals. Color me impressed. Try it out if you ar having vibe and control issues. My only caveat would be the hangers. They are working fine, but when I see the RTR hangers I am envious. Improve the axle hangers and this is a world class upgrade that none can ignore. No more wire hangers ever! Joan was at least right about that.

      Can you still jack up the rear using the differential? I saw a previous reviewer explain that this bar prevents the use of jackstands under the axle, but can you still fit a floor jack underneath the differential to jack up the rear?

      • I have the rear swaybar and can still jack and use jack stands; just have to be careful.
