Yeah Ive been looking for a complete parts list for the last couple of years in regards to converting over to awd. Kept getting guys who said they had done it but then wouldnt elaborate on how they got it done.
Bump ftw!

I converted my 08 Silverado 2wd to AWD. I used my existing 2wd 4l80 and had it converted to 4wd.
These are the parts I bought:
Front differential from an 08 Escalade
CV shafts
GM 8.25 IFS ring and pinion 3.73 (all newer awd fronts diffs are 3.42)
Front driveshaft from the 08 Excalade
Rear driveshaft from an 06 4x4 RCSB
NP149
32 Spline input for the NP149
4wd output for the 4l80e
4wd marriage adapter for the 4l80e to the NP149
2 front bearing hub assembly (steering knuckle is the same for 2wd and 4wd).
Things that were fabricated:
Front differential brackets
cross-member
ON GMT900 trucks the frame is the same. It is even notched for the front differential brackets. I test drove a 4wd truck and put it on the rack and measured where the brackets needed to be.
Everything bolted right in place. My Kooks headers even cleared. I did most of the work myself. My brother helped with the grunt work. A friend swapped out the 4l80 output shafts for me. My dad built the brackets and modified my cross-member (again it was already changed for the 4l80). If I had all the parts handy, I could do it in less than a day. The hardest part was getting all the parts.
My truck weighed 4680 after my first mod (Vortech Twin screw). It now weighs 4900. I'm up 220 lbs, but I've done a ton of modding.

Agreed..
Lets see some pics.. I sold the SSS front diff after seeing that it would NOT work under my truck.. I have managed to find a few Esky front diffs.. do they have any wires going to them for operation?
POST UP SOME PICS!!!!!!!!!!!!!!

this would be awsome for me...id def do it if i could get everything for a good price. i could always use some instant traction after the converter swap
