Driveshafts
Can anyone tell me if they make any one piece driveshafts in the HD trucks that come with 4l80e transmissions? My 1500 crew cab shaft is a single piece aluminum and is a little short for my 80e swap that i did. Its already 80-81 inches in lenght from joint to joint and the drivetrain shop wont lengthen it or make me a new one. They will however cut a factory one down if there is such a thing. I was thinking maybe something from 1500hd, 2500hd either crew cab short bed, ex cab short bed, or even maybe a long bed truck. These need to be 2wd too.

And from what i understand, a lot of driveshaft shops are quite leary about anything > 72" long.

2-piece steel would be stronger due to short shaft sections.
Hey Dub, why not call Denny's Driveshafts and have them make you a driveshaft? They have an awesome rep and would probably know exactly what you would need if you give them the measurement from the tranny yoke to the pinion yoke. They do this all the time.
There not too expensive either. I'm sure they sell some pretty tough U-joints as well.

Aluminums must be worth a **** if GM puts them on the diesels and they can put down four digit tq numbers with them. They're most likely at least twice the wall thickness of the steel though. Also in order to get a ds that long that's 1 piece, it needs to be as light as possible for ease of balancing. The only reason I think a diesel shaft wouldn't work in our situation is that they don't spin to 6000+rpm.
A 2 piece steel driveshaft with carrier bearing from Denny's will run you over $500.
