I found this blurb from a GM truck forum about the driveshafts.
Visited a Chevrolet dealer today with a magnet in hand.
Crawled under every Silverado 1500.
The models having a one piece aluminum material drive shaft are double cab with 6.5' box,
crew cab with 5.5' box.
The model having the two piece steel material drive shaft is the crew cab with 6.5' box.
The model having the one piece steel material drive shaft is the Z71 off road crew cab with 5.5' box.
Regular cab both 6.5 ft and 8 ft boxes have one piece aluminum material drive shafts.
Those models were the only models the dealer had on the lot.

Rather than start another thread, I'll ask my question on this on this one. I have a `17MY Sierra 6.2L 4wd Double Cab. It is the wife's daily and occasional tow rig (3,500-4,500lb race cars w/open trailer). Since its the wife's daily, reliability is paramount. It currently has a 2.9L Whipple. I will be adding the following:
- Texas Speed Long Tubes/Y pipe
- Loudvalves 3.5" cutout mounted upstream of the stock muffler
- 3.75 pulley (gain back the ~ 2lbs boost that will be lost with free"er" flowing exhaust)...vs. 4.0 pulley incl with kit
- Aklycontrol.com meth injection kit
I have 17 C7 Z, so I have gotten "comfortable" that with the meth injection and a conservative tune, I can get the engine to live with the 8-10lbs of boost. As I have gone thru the forum, it looks like the driveshaft becomes the next weak link. I assume that it has the alum rear driveshaft, given that its a 4wd Double Cab. Therefore, it looks like it needs to be upgraded for safety while wife is driving and for when it goes in for tune after exhaust/pulley. What are the "BEST" different driveshaft options? I can do a google search but would like to get the opinion of guys that upgraded. Thanks in advance.
