DriveShaft question
does the gt 5.0L use the same driveshaft as the 3.7L v6 mustang? Can someone please tell me why I am reading so much about the driveshaft blowing up on the 3.7L V6 mustang. Is this happing on the GT 5.0L mustang GT?
Thanks.
Thanks.

drive shafts blow on the V6's when people get rid of the 120 or so limiter or so it was reported on Autoblog. Seems like the ds isn't meant for mush more rotation. Also the V6 I thought is a solid and the GT is a two piece.

The v6 one is built more for economy, meant to handle lower rotational speeds to keep the rpmʻs from building to fast at higher speeds i think. Thats why when you go past 120ish its rotating faster and longer then originally designed, the joints start gettin off balance causing it to tear itself apart.
The GT ones sre built thicker and joints stronger to handle the much higher tourqe numbers/potential. Which is why they can handle speeds over 150 without any problem.
I wish they both came with an aluminum one piece so we can all really stretch them pony legs out

GT shaft is a "True" two piece shaft, as it has two separate shafts with a carrier bearing in the middle, is MUCH stronger than the V6 shaft. The two short shafts in the GT(and GT500) allow for much higher power handling as well as higher shaft speeds. And the GT shaft uses a CV style joint instead of a slip spline to allow for it's articulation. The V6 shaft is also a two piece shaft but the way it works is that one piece slides in and out of the other piece allowing for the articulation of the rear axle.
Back when I had my V6 I was toying with the idea of adapting the GT style shaft to it for a cheap upgrade. I bought the parts to do it but traded the car off before getting it done.

The GT is limited at ~145mph, and I'd imagine the GT drive shaft looses structural integrity closer to 160 or so. But that's just my somewhat educated guess. I haven't seen any GT guys blow out their drive shaft yet.

There was a good article on this a while back. I think the V6 has 112mph limiter, and the shaft looses structural integrity around 130mph.

2011 GT is limited to 155 mph.

Interesting... I remember reading a statement from Ford that they are limited at "about" 145mph. But it could also be 155mph for 3.15, and if the method of doing it is a rev limiter in 5th and 6th this could very well translate to limitation of ~145 on 3.73 equipped cars.
And if that's the case, the drive shaft should maintain integrity over 170mph to provide a good safety margin. Of course that depends on gearing too, as cars with higher gearing will have higher shaft speed at same vehicle speed.

So a one piece will still have to have a sliding part on a yoke into the transmission or inside the shaft itself to allow for suspension travel.

I had a shaft masters Aluminum DS on my 2011 v6. Sold it for a 12 GT ad kept the DS. Sent it back to shaft masters and they cut approx. 3" off of it, re-balanced and changed the flanges to match the GT! DS fit perfectly. so they are different in length from v6 to v8 even w the same transmission.
