Al d-shafts

hey guys,
On my 65' Stang, we put an aluminum driveshaft on it to lighten up the weight, and it overall helps lessen the vibrations from the road. What is the possiblility of using aluminum driveshafts on a 550hp Bronc? Would they be more cesseptable to damage from enduring off-road abuse?

Re: Al d-shafts

Late-model 2WD F-150's use them, and the whole F-series might, so Ford thinks they're OK for at least some truck applications.

Aluminum is more brittle than steel, meaning it cracks rather than stretches when it gets deformed. (Ever see an Al rim that's hit a rock?) It's also not as strong by weight. These 2 factors mean that an Al shaft has to be bigger,thicker, and more precisely engineered than a steel one would.

I'd just get the steel one balanced.
