aluminum driveshaft on NNBS
#11
I talked to a few other gear heads today to get input, and since I've had mine to 120ish on many occasions, they don't seem to think it'll have any problem at the track. I'm just the paranoid type

That's interesting... Mine might be a tad longer, but it is the 5". I've got 3.73s as well. I think the issue is that the aluminum shafts are more sensitive to balancing than the steel ones are since they're lighter. If both shafts threw a weight, or are out of balance to begin with, the aluminum would be in deep **** relative to the steel one.

have 180,000 mile on my 1 piece, have had it to 141mph and over 120mph many times, get the vib at 100 too, its like a light switch, smooth, vibrates, then super smooth again. i have it speed balanced a couple time though when i first felt that common vibe, so maybe thats what has saved it.

Going to bump an old thread because I have been talking to driveline people for the last few days. The general consensus is that in the driveline world its not recommended to make a one piece driveshaft over 68inches long. Some have said they would do 70-71 but that's right on the ragged edge. My drives shaft for example is 82in long. What I have come up with is if I really want to safely go over 100mph+ and not have to wonder when it will bite me in the rear, is to have a 2 piece drive line built and fab a crossmember to support the carrier bearing.
