From what I understand, that’s the reason they make 2 piece shafts, to make them more stable at higher speeds. Also in trucks they could be used to increase the angle from the trans to the rear end.95tbirdguy said:This is 95tbirdguys' brother. I read the artical about driveshafts and them spinning and breaking and i was wondering something. My car is a 95 nissan 240sx and my driveshaft is a two piece. It goes from the tranny to a joing that freespins and is bolted to the body and then it goes to the diff. You cant take it apart. I was wondering if since it was a two piece if it would be more stable and me able to handle faster speeds and more revs than a one piece.
