Parts swapping question

[oefvet0708]

I have a 99 2500 w/t 4x4 with cable shift transfer case and it came with a 5.7 and 4l80 and 8 lug axles. It ran-ish a couple years ago when I pulled the engine and tranny and haven’t messed with it since. It honeslty needs quite a bit of work in the interior and engine and tranny are still sitting in my garage. Can I swap the suspension and axles from the 3/4 ton to my 98 1/2 ton 5.7 4x4? Also the 1/2 ton has a 6” lift if that matters at all. I’m pretty new to the gmt400 scene and not sure what is and is not interchangeable. Just kind of a thought of swapping parts around.

The engine is a bolt in, the trans will go in, but need to rewire it and run the ECM out of the donor. Could swap whole wiring too. The rear suspension will swap over, but not the front.

Ok that was my main question was about the front. So no way to swap in the larger front diff and axles then to match the 8 lug rear diff

@offroadtahoe has a running thread on this, read it here:

It’s not a simple bolt in.

You'd be better off getting the 2500 up and running.
