GM single-piece driveshaft

I have a 2001 K2500HD/8.1/Allison/crew cab/short bed. replaced the support bearing a couple years back and I'm getting a shudder on takeoff again. The solution is a one-piece driveshaft.

Does anyone know a source for these, or know the proper length for a GMC with the configuration above?

I think there is another solution, I would avoid a one piece driveshaft on a long vehicle.. too much of a chance of issues..

nope center bearing just wears out with a pronounced shudder when changing speed. GM's fix is the single piece. its truly a monster, like 5" dia.

I suppose if someone made a quality center bearing.......

You should be able to locate a driveshaft shop to see what they say/recommend--this is a known problem with GM shortbeds? Being a Ford guy, don't keep up with GM, got enough of my own problems...

You need to contact Tom Woods custom drive shafts (1-877-497-4238). They are great guys and can take care of any drive train problems you may ever have. They have saved me many times over the years.
