Well you know what they say about assumption. I am currently working on my ME degree (part time)and work full time in a materials engineering lab.

It's not like I'm pulling this out of my ass nor did I say within the next year every al driveshaft will break. My point was this steel has a fatigue limit, you can cycle it an infinate amount of times and as long as you don't hit that limit it will last. Al on the other hand will weaken overtime and eventually break. Stock ls1 Al driveshafts have been broken by stock power or close to stock power cars that hook hard numerous times.


As for you trying to make me look like a moron by bringing up GM engineers, concept cars and every ls1 breaking a driveshaft in a year ..honestly, the Al driveshaft was a smart choice in that it works and it is cheap to produce. All I was looking for was something to back up your comment about the stock ls1 driveshaft being fine, which you failed to do. He asked about an aftermarket AL driveshaft then asked if there was anything better. I was pointing him in the right direction.
