Can i take my stock 1500 GMC driveshaft which has a huge diameter and use it on my duramax?

Reason I ask is because I can have this driveshaft shortened instead of my dmax stock shaft lengthened.
But the dmax shaft is alot skinnier so I didnt know if this mattered or not

what do you mean why? Why do you think? :secret:
I mean why not just have the stock DMAX shaft lengthened? Would it be THAT much cheaper to have the 1500 one shortened (if you could use it ofcourse which I doubt) ..Id buy your 1500 one but I iz broke until my house gets built.

The joints won't be the same, the 1/2 ton shaft is aluminum, not steel and you'll probably wipe it out loading the converter and jumpin on it from a stop at some later date.

Does that help.

The 1/2ton shaft will probably have a thinner wall tube than the 3/4ton shaft.

what they said, if you pick both of them up youll be able to tell a difference in weight your original one will be heavier

so i should defintely have my stock hd shaft extended?
I thought that was obvious? Sometimes I worry about you

1500 Shaft - aluminum and different joints
2500 Shaft - Steel and correct joints

Not only do you have a greater chance at breaking your 1500 shaft, but you'd also have to swap out the joints to make it work. So really, is that 75$ looking that much more appetizing?

I just like to be very clear on things
