    I don't know. I know they can be found on vans since the mid eighties at the latest.

    Good for a race car but bad for a wheeler. The aluminum shaft is lighter but also won't take too many abrupt bangs against a rock or whatever.

    When I took my driveshaft in to get shortened last week they had one laying on the counter at the shop. It was in three pieces. Looked like they hit something and it all just twisted up until it broke. They also had some busted pinion yokes off a big rig. /forums/images/graemlins/shocked.gif

    I dont get into too many situations with rocks, mostly beach sand. I know that the theory is that it takes less hp to turn the aluminum.

    I have no idea of the application, but I saw a carbon fiber one come through UPS once. It was huge and as lights as a feather as they say.. Bet it would explode if bounced off a rock under torque.
