      Video Review & Installation

      So the SR Performance Aluminum One Piece Driveshaft is a great option for the '96 through '04 Mustang owners out there that are looking to shed some weight from their drive train along with strengthening their components, proving their launches an acceleration. That factory driveshaft is not only heavy but it's just not that tough and it's more likely to fail, especially if you're gonna be dumping your clutch a lot on the track. Install wise, I'll be giving this a light to a moderate one outta three wrenches on the difficulty meter here and about a two-hour job. I'll have a little bit more coming up for you on that later. So you've had your Mustang for a while or maybe it's just new to you and you're wondering, "Why get an aluminum driveshaft or just a new one?" Well one aftermarket driveshaft does a lot much more than just shed actual weight off the car. Less weight in terms of a driveshaft and how it functions means your engine can ride faster and that results in putting more power down and reducing parasitic loss. Now the stock Mustang driveshaft is made from a heavy steel and is more or less designed for the life of the car. Now it produces a fair amount of noise, vibration, and harshness, and it's not really geared towards a car that seeing a lotta track time or just in general, spirited driving. So the heavier any rotating part on your car is, the more engine power is used to move them. When you lower that weight and free up the engine, you make it work less, which again, is gonna result in getting you into that power band that much quicker. Now this aluminum driveshaft is not only gonna be a great option from a weight savings perspective as by greatly reducing that rotating mass, you're gonna be improving your Mustang's quarter mile times, along with off-the-line acceleration, and even cutting down on your 60 foots. But on-road benefits aside here, guys, we're gonna see that this is manufactured out of a lightweight three and a half inch diameter Alcoa's certified 6061-T6 Aluminum, that is gonna come along equipped with a new pinion flange and a 1330 series U-joint. I can't stress it enough here, that weight savings is another great variable about this one piece driveshaft versus the factory equipment, as this is gonna come in at 13 pounds over the factory's 21 pounds, which is apparent right outta the box. Now it's not just a matter of it being a slight diet. Shaving that weight is amplified as cutting down on that rotational mass, in turn, creates better performance. Looking at the pricing, guys, expect to be spending around 450 bucks to get this onto your car. And then switching gears to the installation portion of the video. Like I said a little bit earlier, this is going to warrant an easy but an involved one outta three wrenches on our difficulty meter here, about a two-hour job with a fair amount of tools. So you'll start by getting your rear end up in the air either with a pair stands or on race ramps and then locate the four bolts that secure the pinion flange, which is located at the rear of the car. Now you may want to use a swivel to get a good grip on the bolts, and if they're rusted, make sure to hit 'em with a lotta lube or heat 'em up. So if you're using ramps and you have difficulty accessing all of the pinion flange bolts, simply lift the rear up slightly and then just rotate the drive shaft. And before removing all four bolts, make sure to get a jack stand or a similar support underneath the old driveshaft just to prevent it from dropping down. But once they're loose, you're gonna wanna slide the driveshaft rearward and away from the trans. You're gonna wanna watch out for any fluid that may be leaking out of the trans as well. Now if the rear is elevated higher than the front, this should not be an issue for you. But once you're done there, guys, carefully slide the yoke of the new driveshaft into the end of the transmission and then locate the four original bolt holes in the diff pinion flange, reinstall the original bolts, and then tighten and torque them to spec. So that'll wrap up my quick review of the SR Performance Aluminum One Piece 31 Spline Driveshaft, fitting the '96 through '04 Mustang GT, the '03 through '04 Mach 1, and the '96 through the '98 Cobra, that can be found right here at americanmuscle.com.
