    aluminum vs steel driveshaft

    i just got my 3.73 12 bolt in and love it over my 2.73 gears,

    now, i still have the stock steel shaft in the car and with the weight and speed it is traveling im sure it is draining some power,and from what i have heard the aluminum is alot lighter and stronger, soooo.........shouldn't i get one? i dont think it will make a whole lot of difference off the line but 60mph and up it should help with those gears....

    anyone else do this before?

    I did just the opposite. Aluminum stronger? Hah!

    Being as you're an automatic you'd prolly be safe with the aluminum one. I don't think it made any difference performance wise tho.

    4,500-5,000rpm launches on ET Streets w/4:11 gears with a Mcleod kevlar clutch. Aftermarket aluminum driveshafts will be stronger than a stock alum one.
