does anyone know where to get a good driveshaft for the crew cab nnbs silverados. i already know of one 06 driveshaft going out at 90 and i dont want that happening to me. i just need one that should handle well at 100-110 mph range. any suggestions?

 

Welcome! Do a search on here for "driveshaft" under Drivetrain and Suspension and also under General. I do not know of a place myself, but I know that question has come up a few times before.

 

So the NNBS crew cabs are one piece too, are the extended cabs? I thought they changed both to 2 pieces.

 

I just had mine blow out on me last night! It was a 61" steel shaft. It was alittle scary! I just passed 120 on the speedo then I got a bad vibration... let out of the throttle then boom! I made skid marks on the highway. I guess when the drive shaft hit the pavement it locked the rear for a bit before it broke away... Im trying to figure out what drive shaft to go with. The shop said they could do 3.5" tube front to back with .083 wall tubing vs the 3" to 3.5" with .063 wall tubing. That would be using the stock joints. Or they could do a 4" steel driveshaft with 1350 joints...

 

10,000rpms balancing WILL solve the problem

all you have to do is to find one who will do it lol

 

which company have u been talking to?? I'm wanting to get in touch with one.. lemme know plz

 

If you are putting trans in second gear on dyno isn't that going to give you false numbers?
