I was reading the tech article on speed limiter and drive shaft secrets and was wondering if that is what happens to one piece drive shafts what happens If you have a 2 piece?

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.

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.

It was probably cheaper for the manufacturer to make the 2 pc driveshaft out of "cheap" material and not have to balance them to a high tolerance vs. using a more expensive material and having to balance it to a high tolerance.

Generally though, for performance a 1 pc is preferred. Probably aluminum or carbon would be a good choice.

Are you referring to the 2 piece Mark VIII driveshaft for your TBird ??

What that means is its a single driveshaft with an inner and outer core joined together. The one piece driveshaft is solid but they look almost the same.
