Hi Gang - I am looking to swap my 1 speed transfer case (NP0 option) out for a 2 speed transfer case (NQH option). So far I know I will need the TC itself, the 4WD switch, and the appropriate TCCM.
I've listed the parts that I believe to be correct to do the swap. If any of you that have done this swap or are knowledgeable could confirm or correct my choices, I would greatly appreciate it. I got a great deal on this truck, just didn't have the 2 speed TC option. Working on building it up as an overland vehicle. Thank you all!

Transfer Case
For the TC I am finding 2 options. I'm hoping someone can point me to the correct one for my application. I have a 2017 GMC Yukon SLT 4WD, NP0.
This one claims to be 5821 option and looks like a decent price.

This looks like it should be correct for the 2 speed transfer case

4WD Selector Switch
Looks to be correct
