Best mod ever: new drive shaft
Bought an aluminum drive shaft from Doghouse Diesel ($520) and had it shortened 2 1/8" at a local machine shop ($110). Best $630 mod ever. My takeoff shudder is gone. My truck is smooth again. I wish I could have done this years ago.

I have the NV5600 6-speed. The new Mopar drive shafts are made for the auto's or the G56 6-speed. The NV5600 is about 2" longer than the G56 hence the need to shorten the shaft.

My luck I'd be polishing it and knock off one of the weights. The guy at the machine shop said that the aluminum shafts have to be balanced to a lot tighter tolerances than the steel ones.
Dodgezilla: It took me a while to convince myself too. I have 173,000+ miles on the truck and I was sick of the start and stop vibrations. I had the u-joints replaced once and the shop that I took it to didn't align the two-pieces of the shaft the same when they reinstalled it. This caused a vibration on its own. I then played around with lowering the center carrier. Non of that helped and non of it compares to how it feels now. If you need the shortened version of the shaft just make sure you measure your existing one and make the new one match.
You won't regret doing this.

The NV5600 is 2" longer than the G56 so it sticks out farther towards the rear-end which is why the shaft has to be shortened.
If you only have 50K miles you are probably good for now...
