Aluminum Driveshaft Strength?

I have an LS1 driveshaft in my car and i'm starting to question it's strength over the stock steel one that come's on LT1's.

Are the aluminum one's actually stronger? Or are they just better because they are lighter and are better for drivetrain power loss

PLENTY a post on this subject | just do the search thang

to summarize though, the word is 1LE is strong & aluminum. LS1's do twist on rare occasions. If you're not pushin' some serious HP, I don't think you have to worry. If you are, well, time to save up for a custom steel shaft

I know of two people that have twisted aluminum drive shafts. One was making ~400HP and the other was making over that. I would get a good solid steel one if it were me.

I can tell you from experience that 350rwhp will do this on sticky tires.

Besides the fact that LT1 shafts tend to be out of balance, they are indeed very strong. No substitute for carbon fiber, however.

Anyone know a documented case of a 1LE failing?
It's stronger than the LS1's that are twisting up and failing...

The 1LE aluminum driveshafts like most GM products aren't constructed very well. Get an inland empire. 100% better constructed and race proven. THere's plenty of cars making over 500hp with
alumium shafts on them. It's all about the build quality.

Isn't this subject somewhat related to the weak 10 bolt theory? An M6 car is going to be harder on a driveshaft than an automatic car is.

my friend has twisted that too (well snapped it) but since they are so expensive, some places will rebuild them
