Okay, so long story short, I might be getting ahold of a wrecked 08 z71 4x4 3.7 for cheap. And I would like to know how hard would it be to swap out the engine, trans, and 4x4 components over to my 06 z71?

An 08 can be swapped into an 06 because Kevin has proved it but it is a lot more work then probably worth.

You need to look for an 07 if you want to do a straight swap.

That part I know nothing about, I'm sure the SAS guys can help you on that. I know it requires wiring harness and maybe computer relearn on top of all the labor to get it done.

Just sas it. Probably cheaper and more durable at minimum. And your lifting options are endless.
He may be ok with the 08 engine if he has the harness and CPU.

Ima say your best bet will be to run a Dana 300 tcase instead of the stock one. Will save you a ton of headaches for trying to get it wired and operating properly. I'm getting ready to swap mine out for one. I just swapped trans from a 5speed to auto and I believe my truck won't go into 4lo. Only tried once and it was before the trans was rebuilt. Advanced adapters has the adapter plate and stuff for a 4l60e to dana 300 tcase.

what I was hoping to do was just take all the 4x4 components out of the donor truck, and possibly the wiring harness and just swap them over to my truck, but then I read up on all the 08 3.7 motor/wiring differences and got kinda lost... can anyone tell me if I could still use the components off the donor truck, then at most just get the wiring harness/computer from an 04-07 4x4??

I forgot the 08 uses the CAN system or some shit. To use the 08 engine kmac had to add a sensor to the head I believe. You'd have to get an 04-06 or 07 harness. You can use your stock PCM or have limeswap or someone reflash it.

I can't really think of a good reason to use a 2008 versus 2007. There's just as many 2007s in the junkyards and they're cheaper.

I'm gonna be getting an entire truck with just frame damage, and front 1/4 panel damage, but suspension, engine, and entire rest of the truck is just fine, plus it's got bucket seats in it which I want.... im gonna be getting it for around 600. I'm definitely gonna get the truck, i plan on parting the truck out for a profit, but I just didn't know if I could use the 4x4 components off of it, instead of selling it.
