- Mustang Aluminum Driveshaft Installation Guide
Hey everybody, I'm Justin with americanmuscle.com 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 americanmuscle.com.

I had a vibration around 55 which I thought was unbalanced front tires. After 4.10s I got even more small vibrations in the driveline through my shifter. After installing this guy my small driveline vibrations and the larger vibration at 55 are gone. Construction appears to be top notch, this looks substantially stronger than the stock DS.Helpful (1)

1 star for AM not the part
Received this part in a re-taped box. Took part out of box full of greasy finger prints and witness marks on rear coupling flange from bolts being installed. The driveshaft I received has clearly been installed / tried out already, This is not the first time I have received previously installed / used parts sold as new from American Muscle. As for the part itself I had to change front yoke for my 4R70W auto trans application and have re-balanced at a local drive shaft shop. Worked out great. I just wish American Muscle would stop selling already been installed / USED PARTS as NEW!Helpful (3)

The best replacement driveshaft
Immediately could tell the difference. This driveshaft was a bit longer than the original which made it a tight fit but it feels much lighter now and is much more responsive.Helpful (2)

Didn't need it in the end
But i was impressed with the quality of it. ________________________________Helpful (1)
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.
Will this fit a 2001 Bullitt?
Yes, this aluminum driveshaft will definitely fit in your 2001 Bullitt without any problems!
How much does this driveshaft weigh?
This weighs approximately 17 lbs.
Will this fit my 98 gt?
This driveshaft will fit all 1996-2004 Mustang GT models.
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.
Unfortunately we do not carry a yolk or driveshaft that would be compatible with an automatic 2003 GT, however I would recommend looking at Ford Performance part number # M4602J-K, and you would need a 31-spline yolk compatible with your specific model mustang.
This will not fit automatic transmissions.
This is for manual transmissions only.
This could be a number of issues ranging from loose flange bolts or an issue with the transmission itself. Unfortunately, we would be unable to verify without looking into this in person and would suggest having a shop take a direct look into this in person in order to diagnose the issue.
That would be 45.5".
The Ford Racing drive shaft fits 96-04 Mustang GTs, 96-98 Cobras, and 03-04 Mach 1s with manual transmissions. This will not work with the automatic transmission.
The Ford Performance Aluminum Driveshaft - 31 Spline (96-04 GT, Mach 1; 96-98 Cobra) does not have an exact horsepower rating. If you are concerned with whether this will work with your build or not, I would recommend emailing or calling us and one of our Mustang experts can help determine if this driveshaft would be the best for your application.
The Fox length driveshaft would not work with a terminator swap as a different length would be required.
The spline type needed is determined by your transmission type; 28 spline transmission or a 31 spline transmission. (The spline that is referenced here pertains to the transmission yoke on the driveshaft assembly and not the car's rear axle type). This will not be compatible with automatic transmissions or 1999-2004 Cobra Mustangs but will fit 96-04 Mustang GTs, 96-98 Cobras, and 03-04 Mach 1s with manual transmissions.
This driveshaft is 45.5 inches in length.
