Hey guys, here's a picture of my rear driveshaft along with the front one. My truck has the tow package and I've been told by several guys that own similar trucks that they don't have this fat rear driveshaft:




Is it pretty common? Can it hold high horsepower? I'm wondering if I can just have it shortened for my 80E swap or whether I should fork out for a custom steel one. Anybody twisted one of these into a pretzel?

thats the stocker shaft for a one piece. it is paper thin and full of foam. snapped, twisted, broke, you name it...we've done it. I love my 3" steel shaft. Heavy but speed balanced and solid as a rock. (put some loops on that bitch though)

That's what I kinda thought. It's going into the garbage and a steel shaft it shall be. Thanks, guys.

I don't make enough power to need more than the stock shaft.

I know the thin steel ones break all the time(mine include), but has anyone broke the stock big aluminum one? They were put on by gm instead of the steel because they're suppose tp be stronger at that length. I also read aluminum handles more tq, and steel can spin faster?


edit: on a side note, great title

I thought the same thing as i too havea factory alum shaft in my Dmax, but i learned that these shafts break at high speeds, due to having a low critical speed rating. They like to twist apart at 120 mph from what reaserch ive done.
