Most guys are fine who do this mod. There is nothing that says you can't replace the DS, but I don't think it's imminently important. I never noticed any issues on my DS before or after the gear swap. All I can tell you is that there are a number of guys who do the same mod and keep the stock DS.
Like I said earlier, there isn't much else I can do to my car performance wise besides headers and x-pipe (I have a lethal x-pipe in my garage), so I mainly got my DS to help improve acceleration, lose a little weight, and to help support a super charger if I go that route since it can support up to 900hp.

I meant the Speed Limiter, it was early when I made the post and just woke up. and as for the OP, his car was a car I owned & traded it for a GT. I know the car pretty well and after having watched videos, heard first hand accounts, and taken the car to the limit, I can guarantee ya he better replace the drive shaft if he plans on pushing that thing past the limiter.
So why don't you sit down and STFU

You dont NEED to upgrade the driveshaft... before I traded my '11 V6 with 3.73s in. I had close to 34,000 miles on it... all on the stock driveshaft.. and I made more 140 mph runs than I could count. It did vibrate alot at high speed, but never broke.
OP, is yours an AUTO or Manual? I think the Autos are more prone to breakage at high speed but I could be wrong.

I've only heard of them breaking on the dyno. My buddy's broke twice and he is the reason a certain company no longer carrys 1 piece aluminum driveshafts anymore for the v6 mustangs. It was rated to handle 600hp and his snapped at 289rwhp lol. He won't dyno it anymore but I'm sure he is close to 300rwhp.

Bingo lol. They tried to make it out like he was trying to make them look bad but he was only pointing out the issue and just wanted a replacement. He has a 4" one piece aluminum shaft now. No issues but he's not running it on the dyno either.

I contacted the Shaftmaster guy to see why they don't supply them anymore and he said it was due to the lack of availability of the weld yoke. That doesn't make any sense to me since I thought that the weld yokes were pretty common across Ford vehicles. I could be wrong though. I highly doubt the 3.7l uses some unique weld yoke no one can get otherwise no one else would be making shafts for the car.
