      Review & Installation Video

      Hey, Stephanie with, and this is my review of The Driveshaft Shop's carbon fiber one-piece driveshaft for 2015 and '16 GTs.A carbon fiber one-piece driveshaft is going to be for any S550 owner that's looking to strengthen their driveline and drop some weight while they're at it. The 2015 Mustang still comes from factory with a two-piece driveshaft, which is going to inherently have some weaknesses. A big thing to call out here would be that the DSS driveshaft is going to be much lighter. We know that the stock driveshaft weighs roughly 33 pounds, and I have the scale to measure this carbon fiber version, which looks like it weighs right around 26 pounds. Now keep in mind that we do have the adapter plate on this guy, which is going to add a little bit of weight to this. The weight savings here should mean improvements such as faster revs, better throttle response, and less vibrations or clunking during driving.And looking at these driveshafts, I can tell you that I like the trans end for the manual version because it has a hearty flange with a solid-looking U-joint, and I like that the differential end for both options has a nice CV-joint that's going to be more stable than other options, like a slider. Another thing I like is the carbon fiber. The carbon fiber version is going to be lighter than even the aluminum one-piece driveshaft, and I know it's more expensive, between $1,300 and $1,400, but I think a carbon fiber driveshaft is nicer because of the way the material reacts to hard driving. It gives more of a torsional twist, way more than a stock driveshaft, and even more than the aluminum one-piece driveshaft, but without any kind of reverse snap. And, ultimately, the construction of this driveshaft and the carbon fiber should reduce the shock on other drivetrain components. If we were going to rate the driveshaft options, I'd have it go something like this: your stock one at the bottom, the aluminum one-piece next, followed by the top guy, which is this carbon fiber one. Now, with all of that being said, DSS rates this driveshaft as being capable of handling up to 1,000 horsepower.I would figure on about two hours for the install and about one out of three wrenches on the difficulty meter. You do have to drop your exhaust for the install, and you will need a handful of different socket sizes and hex sockets, and a hammer might be helpful, but you really want to make sure you have a torque wrench for this install so you can torque down your adapter plate and driveshaft insert.Again, the carbon fiber one-piece driveshaft from The Driveshaft Shop does cost a pretty penny, but I think it's a great mod that will both change a stock S550 and is a must-have to support more power down the road. It's at the top of my list for driveshaft options, but, as always, check this thing out online and see what you think for yourself. I'm Stephanie, and for all things Mustang, keep it right here at

        Skeptical at first...

        Picked this up on a great Cyber Monday deal, well worth it! I had been on the fence about switching to a 1 piece driveshaft for a long time because there are so many negative reviews about vibration and having to keep clocking the shaft or having to exchange it. Install was straightforward with the correct allen sockets I was able to toque everything properly, dropping the read transmission mount will help with install. Feels much more direct when shifting, smoother on acceleration, lost all the clunking noises at low speeds that the car had since new. Highly recommend installing a one piece driveshaft!

        Worth doing it right.

        Installed this by myself on jack stands along with a few other suspension parts while I was at it, to prepare suspension and drive train for boost down the line. Wasn't terrible as long as you took your time and had the right tools - do your research and make sure you have the right stuff first (those ball-end allens are key), and it'll go in no problem. Shop install recommended if you don't have the patience. Noticeable difference, car "feels" lighter and more responsive, and I worry less on hard launches with the "springy" tendency of the carbon fiber.

        After a couple drives

        It feels great , I swear I feel the front end lift a little and the rear end squats more on hard accelerations. It also makes me feel a bit more connected to the car or less numb feeling. I did have other mods that might also play a part on that.

        Not as promised

        The driveshaft exploded underneath me during a launch at about 4,000rpm. Car makes 650-700 to the wheels. Did not hold up at all, and it left me stranded. Extremely disappointed, not worth the money.

        Works great and no vibration

        Works great. Easy to install. And no vibrations. A few reviews stated that the shafts were not balanced. Make sure that you reassemble them with the alignment marks lined up. That is how it was balanced at the factory. I have absolutely no vibrations. Much better than the stock two piece with the rubber giubo. No more jerky feeling at slow speeds. Also, many reviews state that you can't torque the front bolts. Use the proper tools!!! You will need 8mm and 10mm ball end allen sockets. 8mm and 10mm allen wrenches with corresponding crowfoot wrenches will work also. But you will have to understand that keeping the crowfoot wrench at exactly 90 degrees will eliminate any torque multiplication. Lowering the transmission mount about 4" helps too. I was installing a new shifter. So this was already done in my case.

        Quiet and noticeable difference

        Pretty easy to install. It really helps to have an additional person inside while tightening and torqueing bolts underneath

        Let's Hope the Second One Is Balanced

        I had my Ford dealer install this driveshaft on my 2016 GT, which has a Phase I Roush supercharger, LT headers and some other add-ons. Under 40mph, it felt snappy and more responsive than the stock one. However, at 45-65mph, it vibrated a lot--enough that it felt sketchy, and certainly was not good on the driveline--so I took it back to the dealer and had them confirm my suspicion that it was unbalanced. It was, so I called the awesome folks at AM and explained. They said send it back for an exchange. I am in the process of doing that, waiting for the next one to be sent. If it is good and balanced, I probably will bump this up to 2 stars due to the extra $200 for the second install (so now this thing is up to around $1600). If it is not, then I am going to call the DS company and request comp for both installs--and go back to the original. I see there was another post here that had a misbalanced one, so out of 11 reviews, two were misbalanced. What is up with the Driveshaft Shop quality control?

        Good Idea with serious engineering oversights

        This is a good driveshaft. But, as another person said, there is no way to torque the front four bolts to specification. No tool exists to achieve the sharp angel needed to torque the bolts to the 54 Lbs specification. This is an engineering oversight that DSS clearly did not address in design and development. I will be replacing the DSS hex cap screws with 12.9 grade bolts that I can put a crow foot adapter onto. Where this driveshaft fails is with the DSS customer service. When I called Drive Shaft Shop to discuss the torque issues and determine what tool they propose I use to achieve 54 foot lbs, the tech support guy was argumentative and not friendly. He said, "we have sold a thousand of these and no has had a problem" After I pressed them on how exactly they recommend I get the necessary clearance to get a wrench on the bolt, the guy said he didn't know, "that they don't do installs and that maybe I should drop my rear axle." Overall its a good product however, I will not buy a DSS product in the future due to how poor their customer service was. If they cannot take the time to install their products (as indicated by customer service) and create a plausible install method, then perhaps they have overlooked other things.

      Both Aluminum and Carbon drive shaft are advertised as "light weight", but how much lighter are they? The videos mention they're 26 or 30ish pounds packaged, but that doesn't help. It would be very helpful to know the weight of the driveshafts.

      • The Driveshaft Shop Carbon Fiber One Piece Driveshaft will weigh in at 24 Lbs. and the Driveshaft Shop Aluminum One Piece Driveshaft will weigh in at 26Lbs.
