    Features & Details

    • Faster Launches, Less Wheel Hop.
    • Lowers 60ft Times.
    • Bolt-On Installation.
    • Strong Steel Construction.
    • Durable Black Powdercoat.
    • Fits 05-14 Mustangs with 8.8" Rear
    Improves Traction. The Swarr Bar is designed to support and strengthen your Mustang's 8.8" 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 2005 to 2014 Mustangs with 8.8" rear end and the straight axle, including 2011-2014 V6 the 2012-2014 Mustang GT 5.0.

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

    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.....

    Which would be more benefical, this with upgraded sway bars and whiteline wattslink or bmr xtreme with watts link, or can this be used with bmr xtreme?


    • The Swarr Automotive 8.8 in. Rear Support will be able to be used with the Whiteline Complete Watts Link Rear Suspension and upgraded sway bars. This will provide the best handling setup, as the BMR Xtreme Anti-roll Bar Kit is designed for drag racing, and would not perform as well as upgraded sway bars for handling purposes. For Drag racing purposes, a Watts Link would not be beneficial, as it will not provide any benefit over a panhard bar for straight line performance. Control arms and the BMR Xtreme Anti-roll Bar Kit would work best here The BMR Body Mounted Watts Links would not be compatible with the Swarr Automotive 8.8 in. Rear Support.

      fits nicely, and with the ability to remove the heavy weights at end of axles; the back end feels lighter and wheel-hop is eliminated. the extra stiffness also helps with launches, and handling in turns

      Superior Upgrade

      This is a quick easy install. I took several hours just becuase I was cleaning up the axle while the car was on jacks. It's amazing how much better the car performs now. I used to fishtail almost all the way thru second gear before she'd hook up and go. Now there's some minor squirm right before the tires grab pavement and she LEAPS forward. I really didn't expect $200 to make this big of an improvement! If you like to drive fast, you NEED this. Cornering abilities have vastly improved as well. Corners I used to slide around, I can now dive in hard and rocket out. THANKS AMERICAN MUSCLE!!!

      swarr bar main feature is keepn your axle from twistn & putn more tire to the ground.

      I put it on my 2011 gt500 . Omg what a diffrence i noticed that the feel of my car is putn way more rubber to the ground. You will see the rubber on the street. My holeshot little better, smashing second gear is where i see the most improvement. Hooks up way quicker . I also think my rear end handles bumps better:) Next step upper n lower rear control arms.

      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

      Swar bar 8.8" Rear Support GT500

      This product is exactly what the back end of a GT500 should come with! The axle is now stable and feels solid under the car, before it felt like it was going to be ripped out. My last dyno on a mustang dyno was 535 RWHP. The car launches better and does not go sideways. This product helps deliver MORE power to the ground. Install was very easy and self explanatory.

      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.

      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.

      This is what all Mustangs need

      If you're like me, you want to be able to throw down the power in a moments notice on the street, while occasionally venturing to the back roads and hitting the corners hard. Previous to this upgrade, launching my Stang (track pack 2013 GT) off the line was a tedious task while yielding subpar results, in my opinion. Lots of wheel hop or just not enough jump off the line... This is the only suspension upgrade I have installed on my Stang, and I really cannot say enough good things as to how much of a performance difference the Swarr Bar has made on my off the line launches and hard cornering on the backroads. The rear end stays firmly planted and doesn't shift around whether its a hard launch or hitting bumps / uneven terrain while accelerating through a tight corner. The Swarr Bar allows you to drive your Mustang the way it was meant to be driven.

      Give your live axle some handling!

      This is a great product with solid engineering put into it. It's a simple, yet cost effective way to settle down your live axle. A watts-link would be best, but the cost is much higher and installation is more involved. If you have access to a lift and power tools, you could have this installed by yourself in a half hour. Crawling underneath with jack stands, I'd say an hour or slightly more maybe two by hand wrenching everything. The Swarr bar fit snug and perfectly, only hard part was drilling the holes while crawling around upside down. Solid mounting hardware, no issues as one tube clamp has a cut out for the breather tube on the axle. I haven't been able to really launch a proper drag strip test, but with the first snowfall today and ice, on all season stock tires, it's much more composed and no squirming. In fact, the traction control just flickers and then the car goes straight. That's a huge plus if you've even driven a Mustang on icy conditions. Usually the traction control cuts in hard as the car jiggers side to side until you let off the throttle or short shift. Seeing SUVs still on season spin all fours and the Mustang pull away from them has me sold on the improvements. I'm still on a stock suspension otherwise, and can't wait till next spring to really get on it at the strip.

      Nice fit, rear feels more solid

      Pretty easy install out side the fact that it did not fit a 2012 gt without modification. Axle has a air vent which was in the way of driver side clamp. I had to machine a hole in the clamp so it would clear. No big problem but it did slow down the install. I also painted the bar red so it matched the other braces that I have installed. Looks great and It does hold the axle straight.

      feels great

      had a buddy install this yesterday afternoon (he has a lift) I really like how it seems to tighten up the rear end on my V6. install was very straightforward except a little nerve wracking having to drill the 2 holes for the mounting. only thing is not sure if its because I have a v6 but I didn't have the weights like it says to remove (just used the 2 large bolts into the existing holes behind the wheels.

      Well worth the money

      What this does is stiffen up the total rear axle assembly. When I looked at it I could not figure out how it would do anything. After installing it and seeing how it is designed I'm happy I got it. The car now still drives normal but when really pushing into a tight curve all of the factory induced oversteer is gone. My car is a 2012 V6 with stock suspension and when going fast around a curve it never really felt stable in the rear but it sure does now. I don't track or race anymore but if I did, This would be a must have item.

      More stable in turns, great for drifting.

      The product is well made, and high quality. I would recommend this product to anyone wanting to improve the cars handling when under throttle in the apex of a turn. The backend drifts out smoothly and predictably giving the driver more confidence. The only challenges were drilling two 3/8 holes into the housing for two included bolts. The other challenge was replacing the 8 short bolts that clamp onto the axel with 8 longer bolts. The included short bolts were difficult to thread, so I replaced them with longer bolts making it MUCH easier to thread the nut(process was difficult because I was on my back working blindly under the car).

      2008 GT500 + Swarr Bar = Awsome Performance

      I installed this piece in under an hour. This bar combined with bolt on sub frame connectors, J&M Extreme Upper and Lower control arms (all from AM) make for OMG performance that can be noticed by just backing out of the driveway.The wheel hop is gone.If the tires would hook it might even pick the front wheels up, (635rwhp,stock tires,LOL..) Really makes a huge difference in cornering as well as straight line acceleration. Rear end is more predictable. Not to mention the impressive looks on the dyno guys face when he goes to strap the rear end down for another run & tune session.Worth EVERY penny.Thank you Eric Swarr & AM....
