Thinking about having a one piece drive shaft built for my truck.  The carrier bushing is going out again, I can feel it thump around when letting off the throttle.  What are the pro's and cons for this?

I can't remember all the pluses I've read, but the only con I recall is cost. It costs a lot to manufacture a spinning shaft that long that doesn't have bad harmonics, etc.

Pretty much that.  The long bed shaft is pretty long for a single unit.   

I have one. Got it from driveshaft specialist out of texas. Its .125 wall, 5 inch dia. aluminum piece. 

 

Pros: less weight, less parts to replace, slightly less jumping around while engaging the clutch.

 

Cons: initial buy in cost, change in low rpm gear rollover noise while driving, cant go over 95-100 mph (may experience sudden rapid self disassembly).

 

They need measurements from you so just be ready to measure your driveshaft.

 

 

It's definitely not cheap, but I figure my auto isn't very kind to the bushing and not having to replace it every couple years would be nice.  I can understand the high speed self disassembly part, but is there any real reduction in strength?  I plan to start installing my compound setup this weekend.  

I'm trying to find the info that I saw a few months ago, but a certain year or years of Chevy Duramax rear driveshaft is supposed to fit our long box pickups with certain u-joints. I'm still trying to find that info again.

@Sycostang67, no reduction in strength.. the company I went with has customers that put over 2500 ft lbs through their driveshafts. Granted 1480 ujoints but still..
