      • Faster Launches, Less Wheel Hop
      • Lowers 60 ft. Times
      • Bolt-On Installation
      • Strong Steel Construction
      • Durable Black Powdercoat
      • Fits 2005-2014 Mustangs with an 8.8 inch Rear


      Improves Traction. The Swarr Bar is designed to support and strengthen your Mustang's 8.8 inch straight rear for faster, straighter launches and less wheel hop off the line. Hook up faster and lower your 60 foot times with this easy bolt-on mod.

      Perfect for Performance Ponys. If your high performance Mustang is pushing lots of horsepower and torque, your rear end needs support to keep from damaging the drivetrain components. A Swarr Bar will help reinforce it to ensure your 'Stang's tire-smoking power is being transferred to the ground, where it belongs.

      Made to Last. The Swarr Bar is made of mild tubular steel and TIG welded for maximum strength and durability. It features a black powdercoat finish for maximum durability and long-lasting good looks.

      Bolt-On Installation. Easier than many suspension mods, the Swarr Bar is a straightforward, bolt-on installation.

      Application. The Swarr Bar is designed to fit all 20005-2014 GT, 2011-2014 V6 and 2007-2009 GT500 Mustangs equipped with an 8.8 inch Rear.

      Technical Note. The Rear Support will not fit with lower control arm relocation brackets.

        Nice product

        Really nice, built strong. Goes good with the limited slip and 3.73 gears to put the power down, definitely recommend for the s197 owners

        Easy install, nice support for 8.8 rear

        Swarr bar was easy to install, fit perfectly and looks to support the 8.8 rear enough for my application. Please note, bolt in LCA relocation brackets will not work without modification because this bar uses the axle weight holes as a mounting point.

        Good support

        Sucks they only offer them in black. If you're in the Bay Area contact collision dr in Hayward. They can hook you up with some good paint work.

        Great idea Eric Swarr!

        This bar is great to support the 8.8 rear axle tubes from cracking off and letting your tire smash into your quarter panel (happened to the American muscle grabber blue 5.0), doesn't take long to install you only have to drill 2 small holes thru the ears on the rear diff housing, great product go buy one! I put one on my gt500 and my drag GT, thanks

        2008 GT500 Swarr Rear Support

        I read some information about the product and what it can do for the vehicle (reduce wheel hop, reduce sloppy rear end feeling, better hook up...). Since the pulley, tune...those issue have gotten worse on my car! I can honestly say, this product has helped in each of those areas...(wheel hop is not eliminated, but greatly reduced). The install is very simple, it was about 45 minutes start to finish.

        5 2014 GT - fordfreak

        works as advertised

        on a lift this part was installed in roughly 17-18 minutes,it stiffened up the tubes nicely. in the s197 chassis the weight of the vehicle in the back is placed on the axle tubes-unlike previous year fox bodies,therefor when the car squats-leans-turns or launches any rear end behavior is transmitted to the axle housing resulting in erratic axle behavior and sometimes damage. what this did was alleviate some of that stress,although I do hear more gear howl and whine-likely due to the fact this bolts to the control arm tabs-and I have bmr control arms attached to umi subframe connectors..all very stiff. this is a good "piece of mind" part.

      Swarr Bar with the Watts Link rear suspension I was looking into upgrading my suspension system for a more rigid, lowered, solid feel with less body roll and wheel hop. So here are my current finalists. 1. Eibach Pro-Street Coil Over Kit (11-14 GT, V6) 2. Whiteline Complete Watts Link Rear Suspension (05-14 Coupe) 3. Swarr Bar 8.8in Rear Support (05-14 GT, 11-15 V6 & 07-12 GT500) My questions were: 1. Would these fitments go together? 2. What more should I be considering other than camber plates and a strut tower brace?

      • Hi, All of the parts listed will work with each over because the Swarr Automotive 8.8 in. Rear Support Item #80801 sits behind the diff cover where the Whiteline Complete Watts Link Rear Suspension Item #54111 gets installed and the Eibach Pro-Street Coil Over Kit Item #47819 replaces the shocks and struts. I do suggest adjustable rear lower and upper control arms, beefier front and rear sway bars and subframe connectors to get the best handling for your mustang.

      traction bars and sway bars... I have a v6 with an 8.8" rear. Im assuming that this is a traction bar.. so here's my question... can install this baby with an Eibach Anti-Roll Sway Bar Kit? Thanks

      • Yes, you most certainly can, Eibach,Ford Racing or stock sway bars will/can only benefit from the stability this piece provides. Installation does not affect the sway bars location,upgades or fuction.It will enhance performance on what ever suspension you may happen to have. I believe it will even work with a sway bar delete/race kit setup...(Not sure because I don't have that particular set up.)It only makes the rear end stronger and has to make it last longer. Hope this helps.....
