2wd to 4wd conversion

Postby Tech4665 [OP] » Jul 17 2012, 10:08pm

okay so basically im stuck. i have a 2008 GMC sierra 2wd and i want to convert it to a 4wd. i found a 2003 Silverado 4wd i can get all the parts off of. I am pretty sure all the parts will fit and every thing but my main question is would i need a newer transfer case module or anything, or could i use the same old module out of the 2003 into my 2008. a technician at GMC said i would need a newer module but other people say it would work just fine with the same old module. i hear alot of problems with it going into 4wd low when the conversion happens.

I'm not sure the parts off the 2003 will work on the 2008 because they are different generations vehicles.

The motor and tranny may be the same but the frame, body and everything else is completely different. Like ASTE25 said, they are different generations.

You should just look for a 4x4 truck to replace the 2wd. Even if you had a donor NNBS, it would be really expensive and a lot of work.

Youd receive none of that money/work in return when you sold it. Hell ide never actually buy the truck if you did that to it....

The 2003 front suspension is a torsion bar and the 2008 is a coil spring suspension. I doubt they will interchange anyhow. Like stated above, it would be cost prohibitive.
