Aluminum Drive Shafts.... thought?

For daily driver I would say it is a waste of money. The only reason I have one on my 51 GMC is that I needed to bolt up to a flat 3 bolt output shaft on my 6061 tremec, and have the in and out capability of a splined shaft and not bind since the rear end is offset because it came from a ford explorer. The company I used incorporated a Porsche CV joint at the front and U-joints at the rear and fabricated it all out of aluminum. It is larger diameter like some have mentioned and cost me an arm and a leg. No, for daily driver I would just go with a steel one but that's just my opinion. Save the money for a tank of gas or something.
