    Haven’t installed yet. Most probably over the weekend. Not sure if to put the car on ramps and jack stands or get it on a lift for install.

    No because I actually removed the factory shaft earlier last year to install the aluminum and at the time I didn’t really care what it weighed.

    Are these Shaftmasters alum driveshafts the same diameter as OEM, or bigger? In case I ever buy one, I'd like to be able to still use my Blowfish bracket (It doubles as a driveshaft safety loop).

    Scroll to 3:54 "they all fit"

    Hope that is true. I run the BMR DS safety loop and it's tight to say the least even with shims.

    Did you receive and install that Shaftmasters unit yet? I'm curious as I only see a 2018 version on their website and my understanding is that Ford changed the Mustang driveshaft flanges from 2018 to 2019.

    QA1 doesn't have a 2019 CF shaft available yet.

    No, I've been so busy with work that I haven't had a chance to. Hopefully this isn't the case, but I did let them know I had a 2019 when I ordered it.
    I was understanding that the flange had changed on the A10 cars.
    That and other driveshaft companies offer shafts for the 18+ MT82.
    Ford also has the same driveshaft PN for 18 & 19.

    Got the QA1 CF DS along with the DSS half shafts on today. Stock DS was about 29lbs. QA1 21.4.

    I can tell you despite the added weight of the beefed up axles installed and the OEM DS and axles in the trunk the car is more responsive and just revs faster. Looking forward to taking it for a real drive after rush hour dies down now that all the extra weight had been unloaded.

    How was the install on the DS? Simple enough to do on jack stands?

    If it weren't for the axles, jack stands would have sufficed. If you can do a cat back on stands then you can to the ds.

    That’s one of the best gains I experienced. The Coyote 5.0 redlines in an instant. It truly transforms the drivability. The shifts hit hard, fast and controlled.

    Drag mode should be a riot. Gotta hit the track before it warms up again (weird week instead of 100s it's been 70s and 80s lol).

    Since you are on the topic of driveshafts ... wanted to share a video review Bran did on the Steeda driveshaft:



    Yes, shameless plus :)

    The Steeda ds looks EXACTLY like the Shaftmasters one! Hmmm??

    Could you give a review of your new driveshaft?

    I was chatting with him on this last week. He was having some unexpected vibrations. QA1 requested he rotate the adapter but that did not help so they asked him to send it in for analysis. Haven't heard back if it was uninstalled and sent or not for sure. I can say personally now after having it on for week and a half no vibrations or NVH increase, much quicker revs and responsiveness. I'm actually not even on ff at the moment as it was time for a tank of 91 and it's still super snappy. Should be back on e tomorrow and looking forward to even better performance/ fun.

    Can't wait to get the drs on and get out to the track to see how the DS performs when pushing drag mode.

    I'm confused on what you guys mean by increased revs... The driveshaft doesn't move when revving the car in park/nuetral lol. I'm sure you all are talking about acceleration...

    For those that got the driveshaft solely because you're worried about it breaking. If you're only doing footbraking at the track you probably won't ever need one. I've made 20+ passes with the stock driveshaft doing 1.3's. I finally popped it at street car takeover about 30' out and still did a 1.5' lol. Multiple 9.0 passes with the stock driveshaft.

    Sorry to clarify I meant it bangs though the rpms faster, not literally revving in park. Gets to the sweet spot of each gear faster. Plus the responsiveness is noticeably better.

    I finally got around to installing the Shaftmasters. I noticed some NVH(noise mainly), but that could also be attributed to the Steeda Tri Ax Race shifter that I installed at the same time.
    It does "ref faster" and I don't have that annoying clunk I was experiencing with the two piece.

    This is addressed to no one in particular.

    Unfortunately, increased vibration is a risk when going with an aftermarket DS on these cars..

    Unless you’re willing to do what it takes to index and field balance the vibes out after changing the DS, don’t try to upgrade.. These cars are extremely sensitive to the least amount of balance / tolerance mismatch...less than 1.0 g at the flange makes a very perceptible difference.

    Edit- clarity
