    tried to do that but no driveshaft company would make me one, something about it flexing too much over 54" long.

    I appreciate it. I was just curious seems like it would be better with less to break.
    Don't 99-up extended cab trucks have a 1 piece driveshaft? I thought I was under 1 one time and noticed that but may be wrong.

    yes the do but they are about 5" aluminum tube and if you put any real power to them they like to twist in half.

    Usually only 4WD's have one piece shaft with EC, CC, or LB. 2WD generally had two piece unless RC.

    Are you trying to say that I don't make any real power??? I've got the 1 piece aluminum and from what I understand they do ok. The main problem with them is excessive speed. You probably won't be doing many 130+ mph runs with them. It does fine for my application since I'm not spraying off the line and not making any runs over 110. If I was, I would go with a 2 piece...

    how much hp rating would u say? would up to 500 hp be safe or less. My thought was if i start making more hp with a 2 piece i would see the center section exploding but I may be way off track.
