Just another option to consider and this may not be any help. The shop you are going to use to cut and balance the shaft, have you checked with them about making a shaft the right length using your end caps? It might be similar in price....or I might just be spoiled by having a full service driveline shop a short distance away.

Re: drive shaft help

There is no such thing as any specific vehicle to get a driveshaft out of and have it fit perfect. If you have the HD driveshaft and carrier bearing in your truck, I would stay with a 2pc driveshaft and just have the front shaft shortened. If you must go with a one piece, look for a driveshaft that is too long and have it shortened to fit your application. The other option is to have a completely new driveshaft built. That will cost a few bucks for one that long.

Re: drive shaft help

Interesting to know if they made one piece DS 72" or longer in to many vehicles, maybe newer suburbans and trucks?

I had one made by Denny's driveshafts and I had to step up to a 3.5" DS for a 54" length of which they will not go over 56" length in the 3.5", probably due to not taking chances of hitting critical speed and coming apart. My 2017 GMC Sierra has a really long DS (probably at least 72" long) but it's like 6" wide and aluminum. For a LWB, I might consider keeping 2 piece if you can like captain said. If not I would check to see what length and width would be safe for you. It could be that you don't push to much RPM to hit the critical speed issue and might be OK with it. Taking some guesses here for you though.

Re: drive shaft help

I'd stay with the 2 piece as well. Its fairly inexpensive to shorten a shaft compared to building a new one with a diameter to work with that length.

Its also worth noting that with the stock 2 piece, pinion angle shouldn't be a concern. 1 piece will almost certainly need adjustments at the trans and pinion to get DL angles right.

shouldn't have any bearing at all on that relationship.

Re: drive shaft help

well ok it is done. to have the 2 piece disassembled and shortened would be $150.and I would need a new center bearing and some u joints. to shorten a 1piece is $80 but I had to go to a salvage yard and pick one out of a van full for $75 + u joints.
and then there is a new one 3.5 inch with new yokes and u joints ready to install for $250 + tax. so in just over 2 hours I have a new one. had to remove the center support bracket but I think I'm good
