    3pc Driveshaft

    I was wondering if anyone else has had this problem: I have a 2002 GMC 4.8L
    Std cab, long bed, one pc aluminum stock Driveshaft. Was testing out our new dyno at the shop, did 2 pulls on my truck, and on the second one my driveshaft made itself a 3 pc. I know I was going way faster than my truck would ever see on the street, but still dont think it should have gone unless it was already damaged. Any thoughts would be great. I will try to upload a pic for it, gotta figure out how to get it to fit.

    Thanks, I figured that I over spun it, but I was thinking about it, I couldnt have spun it much faster than hitting the speed limiter in O/D. Does any one know the safe rpm limit for these giant driveshafts? I have done short bed trucks with no problems.
