Product Description

Maximum Motorsports Torque Arms
The ultimate rear suspension for your 1979-04 Mustang is now available from Maximum Motorsports. Installing the MM Torque-arm will greatly improve your four-link suspension by converting it to a three-link design. Your car will have vastly improved traction, both in a straight line and when exiting corners. Your car will be much more stable and predictable, and you can get on the throttle sooner and harder while accelerating out of a corner.The MM Torque-arm fits 1979-2004 Mustangs with an 8.8" solid axle. The MM Standard Torque-arm is rated for engine torque levels of 330 to 590 lb-ft.

Tighten Up Your Suspension
In the stock four-link design, the rear upper control arms are trying to do two jobs at once. One is to control axle wind-up, the other is to locate the axle side to side. When pushed to the performance limit, the upper control arms don’t do either job very well. Our Torque-arm suspension system separates the functions of the suspension components—each component has only one job, and is designed to perform that one function with no compromises. The MM Torque-arm controls axle rotation much better than the upper control arms. In addition, the Panhard Bar has the sole job of locating the axle side to side, which it also does better than the upper control arms. The lower control arms primarily have the job of thrusting the car forward under acceleration. The MM Torque-arm suspension system allows complete removal of the rear upper control arms and the quad shocks. The resulting three-link design will articulate freely, even during extreme cornering, acceleration and braking.

Improved Traction
The free-moving three-link design has so much more traction that the grip at the front of the car will now be the limiting factor (understeer). You should now raise the rear spring rate to increase the rear roll resistance, which takes some cornering load off the front. To meet your needs, Maximum Motorsports has determined the rear spring to match your front spring rate (see Spring Rate Table). These selected rear springs will give you better handling and improved ride quality with your MM Torque-arm suspension system.

5 Stars   Tranforms rear of Car to Super-car status!

Image uploaded by DUANE R. The Torque arm in combination with the PHB allows elimination of the Upper control arms and Quad Shocks. The rear of the car now travels without the bound up rear jounce of the factory ride. I have the regular duty and it has held fine for several years behind 633 hp / 629 tq. The car hooks better than ever, and is much more confident feeling through corners. The counter-steering caused from rear steer is gone. It required no exhaust mods to my factory cat-back. Despite what others have said the torque arm works with others sub-frame connectors so long as they are square and steel.

5 Stars   Quality construction and solid engineering

Image uploaded by Chad H. I'm running an MMTA-1 on my 1984. Unless you're going to fabricate your own torque arm, the MM is the way to go. It's a little heavier than some of the competition, but it's better built and better designed. You won't be cracking your floorpan with this one like a particular competitor's offering, and you can still easily remove the differential cover with the MMTA in place.

As mentioned, a panhard bar or Watts link is NOT optional and the MMTA cannot be used without one. A prior review mentioned that you can't use this with stock lower control arms, but that's not really the case. It will still work and provide great improvement even with using your stock lowers - providing the bushings are in good shape. What you don't wan't is any lower control arm with extremely stiff bushings that will not allow the axle to articulate. Ideally, you want spherical bushings on at least one end of the LCA, and something on the other end that isn't too stiff to keep it from being able to allow for a little bit of bind-free articulation.

As was stated in a prior review, this isn't an install for beginners or those who aren't meticulous in their measurements and welding. It will work with any decent weld-on subframe connectors, not just the MM. Do what you can to get the crossmember close to the body before welding the tabs, as your exhaust clearance will depend on it later. Follow the directions to the letter, and you'll be fine.

I bought this before reading reviews,it does not work like a pan hard bar and losing your upper arms is a bad ideal without aftermarket lowers which you have to buy along with panhard bar. So get ready to buy lowers panhard because this won't work right without.

5 Stars   works great "not a simple bolt on"
By on 11/16/2014
I've had this product on my 86 Mustang for almost a month first off this product is not a simple bolt on it also requires other Maximum Motorsports packages in order to get it on your Fox such as the Pan hard bar kit. subframe connectors and lower rear control arms and more all must B Maximum Motorsports. Welding And leveling system is required a hi level of experience and expertise is required for installing . also the horsepower this kit can take is limited by the gear ratio that you are running your tire sizes are also Limited i could no longer run 275\60 in the rear . fender rolling is also required as well.the final cost for getting all these parts on my car was well over $5,000.all this being said it does work awesome and my 86 now drives a lot more like my 2014.

Yes, I would recommend this item to a friend!
