    Review & Install 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

    Improves Handling. Improve the handling performance of your S197 Mustang coupe by replacing that skinny weak rear factory sway bar with a Whiteline Performance Heavy Duty Adjustable Sway Bar for superior handling, flatter cornering and better grip. This Whiteline rear sway bar features a unique reverse-mounted design that helps reduce unsprung weight and allows additional clearance for wider tires.

    Adjustable. This Whiteline Performance Heavy Duty Rear Sway Bar features four (4) adjustment positions for fine tuning the handling balance of your coupe Pony to suite your driving needs from mild to wild.

    Superior Materials. Made from 1-3/32" (27mm) diameter solid spring steel for extra strength, this Whiteline Performance Sway Bar performs as a spring more effectively than hollow, non-spring steel sway bars.

    Application. The Whiteline Performance Adjustable Heavy Duty Rear Sway Bar is designed to fit all 2005 to 2014 coupe Mustangs, including the V6, GT, Bullitt and Shelby GT500 models.Note: This sway bar will only fit coupe versions of all 2005-2014 Mustangs.

    Will this rear sway bar have room for 15 inch drag wheels on a 2008 gt500?


    • The Whiteline Heavy Duty Adjustable Rear Sway Bar will have room for most 15x8 drag wheels, but may require a relocation bracket if used with a 15x10, depending on the wheels offset.

      Well worth the time and money

      The Whiteline Rear Sway bar does make a significant difference over the stock. Be careful as you tighten the u-bolts to not crush deform the mounts on the axle. Also, you lose the ability to place jack stands under your axle.

      Great bang for the buck, excellent first suspension mod!

      The kit took about an hour and a half to about two hours to install and the most difficult part about it was connecting the adjustable hangers. Whiteline didn't include a very detailed picture about the install and there is an offset spacer in the kit that has to be specifically placed, I figured it out after about 15 minutes of trial and error. I installed the sway bar in combination with a new set of Lower Control Arms and cornering is really firm and precise now. As you're turning it feels like you're at the far end of a loaded slingshot and when you exit the turn and hit the gas you straighten out quickly and fire like a canon. It definitely corrects the more cushy/sloppy stock configuration without sacrificing ride comfort. Construction is awesome and fit perfectly as designed (with the exception of arranging the spacer). I definitely recommend the rear sway bar, and will be purchasing the front soon. You might as well replace the LCAs, like I did, at the same time since you'll have the rear jacked up and wheels off anyway. Basic hand tools, nothing special required... even comes with a small packet of grease for the bushings.

      The choice to make if running wide rims in rear

      This sway will give you more clearance for wider rims than the others that install the same as the factory sway. Adjustable end links are a great plus. Installation hint, follow directions for order of operations on install but disconnect one endlink before tightening the U bolts all the way down( where the bar connects to the rear end housing ). This will help prevent bind. Then put the car on the ground to finish endlinks setting. On the second loosest setting it is looser than the stock bar fyi.

      Whiteline HD Rear Sway Bar

      The Whiteline rear sway bar is not bad for the price, it looks good (to bad you can't really see it) and was a fairly easy install. I can’t say exactly how well it performs for sure, because I installed other suspension components at the same time. Overall it seems to be stouter then the stock bar and has 4 adjustments depending on what setting you prefer. In my opinion, medium seems to be a good setting and complements the additional items installed for daily street application. Just remember to recheck all components after 60 miles like the instructions call for. Once again, Thanks to AM for the timely shipment!

      Significantly Better

      I had the opportunity to use a lift at my friends auto shop. It May be difficult install without a lift. Installation of this sway bar is straight forward and easy. It looks real cool and significantly improves handling by leaps and bounds!! The car feels more planted and stable now! It has a slight squeak when launching hard but it's hardly noticeable.

      High Quality and Huge Improvement over stock

      Installed the whiteline front and rear bars together on 07 GT and after adjusting the stiffness settings, car feels completely flat when cornering. Huge improvement over the stock GT bars. Took a couple hours to install and instructions weren't very specific, but was able to figure it out. Otherwise a great looking and performing product.

      Nice piece. Well made. Directions are a little scant to sort out spacers but otherwise an easy install if you have a helper. Not a huge balance difference from my track package bar. At full hard setting, its about 35% stiffer.

      Whiteline adjustable rear sway bar

      Fit and finish is excellent and the adjustable endlinks makes it simply to remove any preloads. I started with another brand adjustable rear sway bar on my 2011 GT but was unable to use the softest setting without hitting the Corsa Extreme axle back. In addition, the other adjustable rear sway bar also does not clear the rear lower control arm reloation brackets. The Whiteline rear bar cleared the axle back and relocation brackets with ease and there are absolutely no clearance issues. After dealing with rod ends wearing out quickly on a street driven car, Whiteline's poly bushings in the endlinks is definitely a welcomed improvement.

      Excellent Product

      I highly recommend the Whiteline heavy duty sway bar. Everything is top quality especially the end links. The rear end is much more firm and smooth feeling. Absolutely night and day difference from the garbage factory stuff. Although I will always have my setting on the stiff/hard setting, it's great knowing I can adjust it to a softerror setting for a long road trip or anything else ad such. And of course American Muscle themselves never disappoint with shipping or customer service.

      Fixed my problem, and more

      I bought this sway bar because I was having the bumping\squeaking\rattling problem. All gone now and the car is better taking corners, and I chose the "medium" setting, as well so I am very happy with this product. The only caveat is the lack of detail in the "installation" sheet which has only illustrations, no pictures or actual procedures. You can watch a similar procedure on YouTube if necessary.

      I purchased this sway bar to rid myself of two issues, the clunking and squeaking of the factory bar and rubbing of my LCA relocation brackets. It does both of these perfectly and the fit and installation is easy, even though the instructions aren't the best.

      Great sway bar

      I installed this bar with the front Whiteline. Great setup. The rear sway bar has a different setup then the stock bar or most aftermarket versions. With the relocation of the sway bar ends, I can run bigger wheels. Really changed the hookup on the car . I have a lot more control of the car in corners. It keeps the tires planted all the time.

      Great Product From Whiteline

      I bought this and installed it so that it would match up with the HD front whiteline sway bar i had installed. With just the front sway bar i found a huge difference but i could feel the movement more pronounced in the rear end. like it was trying to spin out. with the Whiteline rear sway bar that feeling is gone. now my 2010 GT corners like a beast. im very happy with the end result and would recommend this to anyone and everyone. AM was great with their shipping. the part had gone on backorder for a couple weeks but the second it was available it was shipped out and i received it in a timely manner.
