Because i have the truck, It is the truck that my grandpa helped me purchase, so it has sentimental value, and i want AWD because i am tired of snow and **** leaving me stranded and i dont have the storage space to buy a winter beater.. Plus it will make traction a little easier when i get the 408 built..

 

bump on this, still would like to see some pics.

 

bump again... wanna get this done to my gmt800 one of these days

 

But why bump it when no knew information has been added. The chances of new info being added are very very slim. I bet only 10 or 15 people in the country have done this swap. Me being one of them.

 

um because maybe someone has done one yet didnt see this thread to add their input into?

and i thought u did the 4wd to awd conversion? not the 2wd to awd?

 

Bumping a thread isnt a bad thing, as long as someone is learning something. Can't fault him for looking at the thread

 

Exactly, esp cuz there still are people who want to do this, seems to have a decent bit of info in here, not to mention a ******* maro that is being done AWD..

 

Oh. So you need info on 2wd to awd. As long as your truck is torsion bar fron suspension it should be fairly straight forward.

I was not trying to be a jerk even though when I look back It seems I was.

 

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.

 

You just gave me everything I needed to know. I already have the awd 6L80 trans, now I know what else I'll need to get. Thanks bud
