The steel ones should be stronger. I don't have any empirical data as to how much stronger steel is than aluminum; I can't tell you that at XXX torque the aluminum shafts will fail and the steel will handle XXX+. I don't know if anyone could tell you that. I think it's common knowledge that steel is stronger than aluminum, but I can't think of an appropriate way to quantify it in this situation. If jeffvette is correct, and GM did use steel half shafts in certain cars, that would indicate to me that at some point GM was worried about the strength of the aluminum shafts in cars with stock power. That alone is enough to get me thinking about using steel shafts; couple that with the fact that I've broken two aluminum half shafts (with moderate power, 415 RWHP) and making the move to steel shafts makes sense to me. However, assuming jeffvette is correct, GM could have been moving from steel to aluminum to save weight on the shafts. It might not have been a strength issue at all. I've never heard of steel shafts in a stock car before, maybe jeffvette can tell us what the intent was behind certain cars having aluminum and others having steel. |
