Are you shittin me? You couldn't have linked this in your own brand-new thread??? Anyway, to answer your question, no, this isn't an end-all, answer-all thread, because driveshaft balancing (or lack thereof) also majorly comes into play here. GM didn't set up any of the truck shafts (aside from maybe the TBSS) to go 120+ mph, therefore the aftermarket is needed to supply a reliable solution to driveshaft problems for those of us with trucks and no brains.
I thought the failures were related to a lack of high speed balancing but this thread made it sound like length was the main contributing factor causing the shafts to reach critical failure over 100mph.

It's a combination of the two (length and balancing). I believe strength comes into play a bit too because flex will be reduced when the shaft itself is more structurally sound. I haven't heard of anybody blowing the aftermarket driveshafts that have been all the rage in these trucks for the last couple of years, so obviously those are a solid solution to the problem.

where was this..........
Where was this post when I was driving down the road and ACTUALLY learned that 147mph is critical speed and it will not only scare the living crap out of not only myself but the other three buddies, and annihilate a tail-shaft housing, a pinion yoke, sensors, of course the DS and worst of all.......... your pride.
But I would like to know what is everyone doing to prevent this?

Keeping an old thread alive eh?
A built driveshaft would have solved your problems.
Ive been 158 in my truck with the stock 2 peice steel driveshaft. thats was about 6300 rpms for the driveshaft speed, 4700rpms Engine Speed.
