Hey everybody, I'm Justin with and this is my detailed review of the 31 Spline Ford Racing One-Piece Aluminum Drive Shaft available for all '96 to '04 Mustang GTs and Mach Ones and all '96 to '98 Mustang Cobras. The Ford Racing One-Piece Aluminum Drive Shaft is going to be a solid upgrade for any SN95 owner out there. Looking to replace the heavy steel factory drive shaft with a strong and lightweight one piece aluminum option from a trusted name like Ford Racing. This is going to be a great option for some of you owners out there who might be suffering from some drive line vibrations and are looking for an affordable fix. Or on the other hand it might be for the owners out there who subject their Mustangs to some serious track use and are looking for an upgrade in both strength and materials for some hardcore launches. Again guys, this is Ford Racing's 31 spline option here, which is designed to fit the 8.8 rears in the GT Cobra or Mach One. Now on the site we say this thing only fits your manual Mustang. And that is true as this product sits right now. However, you can use this on your automatic equipped Mustang. All you have to do is basically transfer that factory yoke over to the new Ford Racing drive shaft here and you should be good to go. So with the fitment out of the way, let's talk about some of the benefits you can expect when making the switch to this drive shaft. Now one of the major benefits when making the switch to an aluminum drive shaft is the big time weight savings you're going to be seeing here. In fact, Ford Racing's option is constructed from high quality T6 6061 aluminum which, besides being a little bit stronger than that factory steel drive shaft, is going to be far lighter than that steel drive shaft as well. In fact guys, the Ford Racing aluminum drive shaft is going to weigh in around the 13 or 14 pound range. Compare that to the factory steel drive shaft around 19 or 20 pounds and that's a savings of roughly six to seven pounds or over 25%. Which I know probably doesn't sound like a whole lot, but you have to keep in mind here guys, this is rotational mass. Big difference than shedding some dead weight off the car. And why is that? Well, because the engine doesn't have to work as hard to spin this lighter drive shaft, the car overall will feel a little bit more responsive. It should rev a little faster, it's going to pull through the RPMs a little quicker, and you might even notice a slight improvement in your 60 foot time. And maybe even a tenth or two off of your quarter mile time. All right, so we know that this drive shaft will be much lighter than your factory drive shaft and we know there's some benefits that go along with that. But the weight savings is only one part of the equation. This Ford Racing aluminum drive shaft will also be slightly stronger than your factory steel drive shaft, thanks again to that T6 6061 aluminum construction. Along with the three and a half inch thick walled seamless tube. Along with that T6 construction, the Ford Racing option is also packing some pretty serious 1330 u-joints here, which can sometimes be the weak link on the factory drive shaft. Definitely not the concern here with this new after market drive shaft from Ford Racing, as they have been upgraded and are much stronger than the factory units. Now another huge benefit when making the switch to this aluminum drive shaft from Ford Racing is the reduction in drive line vibrations that I see a lot of SN95 owners complain about, at least here on the site. Now that factory steel drive shaft it can become unbalanced or even slightly twisted which will cause some drive line vibrations that do increase with speed. Now by making the switch to the Ford Racing aluminum option here, most if not all of the owners have reported back with great success. It basically eliminated all of their problems. But perhaps one of the best things about this particular drive shaft from Ford Racing is the price. To be getting a brand new, well built, one piece aluminum drive shaft for right around $300 is pretty damn good. And it's by far and away your most affordable option here at American Muscle. Installing a new drive shaft on your SN95 really isn't a difficult task, per se. But of course, all of your work will be done underneath the car, so just make sure you have your jack and jack stands ready to go, race ramps, or a lift if you have access. You're looking at some basic hand tools here, guys. Nothing too crazy. Twelve millimeter wrench, a torque wrench is always a great idea, and finally some blue Loctite for those drive shaft bolts. Now in order to remove and replace the drive shaft, you really only need to remove four 12 millimeter bolts, then replace the drive shaft with the new Ford Racing unit and you should be wrapped up. A couple of hours in the shop or garage is really all you need to tackle this one, guys. And again, very straight forward stuff. So we'll say one out of three wrenches on the difficulty meter. Wrapping this one up, guys, the Ford Racing One-Piece Aluminum Drive Shaft will be a solid choice for your Mustang GT, Mach One, or Cobra and here's why. The benefits and weight savings and strength alone are a huge improvement over your factory drive shaft. And it's all coming for a price that's going to be very hard to beat. So be sure to check out a drive shaft option for your ride right here at

When using this on an automatic GT I am told you can switch the automatic yoke to this driveshaft.Is a different u joint needed or is it plug and play with the automatic yoke?


  • The Ford Performance Aluminum Driveshaft would simply need the yoke swapped, with no special u joints.

Is it save to drive the Aluminium Driveshaft in winter on salty streets? Or should I clear coat it for protection?


  • Aluminum corrodes, however, it will not rust. Aluminum is less prone to corrosion than iron, so it will actually last longer than the stock driveshafts which are usually made of iron/steel. With that said, this driveshaft would indeed be safe to drive in the winter and on salty roads.

Fit a 97 Cobra with a T56 Swap or get a 03-04 Driveshaft then?


  • The T56 transmission utilizes a 31 spline output shaft, so this 31 spline driveshaft would be a good fit for that transmission.

    The Ford Racing Driveshaft is a great way to improve your accelartion and remove some unsprung weight. I installed it in less than 30 minutes. A little suggestion if you dont have a lift, jack up the car from the rear instead of the front so you dont lose any of the tranny fluid when you remove your old drivesahft.

    Butter Smooth

    I have been thinking about putting one of these on my Cobra for quite some time, but was skeptical because of the price of admission. As soon as I dropped it down off of my lift, pulled it out of my garage, I thought goes. I pulled out onto the road and within the first mile I asked myself, why the heck didn't I do this a long time ago? I drove out onto the highway, and just listened to and felt the smoothness of my car. It wasn't until I put this on that I realized how smooth and sound my whole drivetrain was. This is definitely worth the price of admission, and a huge improvement over the massive junk paperweight stock driveshaft. Thanks again American Muscle for great prices, and excellent service combined with the free shipping, you cannot go wrong. This isn't my first purchase from these guys and gals, and won't be my last.

    Stopped Leak

    I do not think the 3 hundo for this shaft is money well spent if you are you going for bang for the buck performance improvements. I felt a slight improvement (might be wishful thinking). It is easy to install, and it looks cool after a good polishing. In combination with a new output shaft seal it stopped my leaking issues, but it doesn't cause the cars around you to melt from the improvement in acceleration. If you have $300 to burn, go for it, it certainly doesn't have any negatives other than you'll have 300 less bucks for other mods.

    did it's yob.

    I only purchased this because after my 4:10 gear swap I had a nasty vibration at the top of 4th gear/end of the quarter mile due to the factory shaft. Right out of the box it had the marks left on the shaft showing the balance was checked. 15 minutes later smooth riding to 120 and beyond(at the track only). Very satisfied.

    If your stang's a daily driver and your the type of driver that notices any change to how your stang drives you will feel a difference. I have every minor bolt-on with stock 3.27's gears and I still felt a noticable difference. Much improved acceleration and smoothes out the drivetrain. Thanks AM!

    02 Aluminum Driveshaft

    This shaft goes on easy and performes well. It only makes sense to lighten your drive train so it can provide more torque instead of absorbing it. Mix this with a lightweight flywheel and you got a winner. Very strong aluminum, holds up against my 125 shot of nitrous.

    This motorsports driveshaft fit my 92 coupe with an upgraded tr3550 like it was made for it. The u joints with out grease fittings are stronger than the generic driveshafts made by others with grease fittings. The transmission yoke was 6 inches long, much longer than stock also.

    Product fit on an automatic gt

    Easy to install product lifting from the rear is the way to go gives you better connivence to remove the four bolts. Not to mention you will not lose any transmission fluid in the process. After thats done you just easily pull out the driveshaft and replace with the new. Only backtrack I had was to remove the yoke from the new one and replace it with the old due to it was for the standard transmission and mine is automatic. Other than that pretty simple self-explanatory installation. For sure better throttle response and a quicker run through your RPMs.
