Can you add a selectable 2wd/4wd transfer case ?
 

I have read that when people get a diesel conversion they get a selectable 2wd/4wd transfer case.
This would allow you to get great gas mileage in the city due to driving in 2 wheel drive.

My question is can you and is there a selectable 2wd/4wd transfer case that would mate and work with our engines and transmission?
say from a 2500 truck/suv?
would you see any pros or cons to this set up?:confused:

I think the H2 is a bit big for an 2x4 drive it just seems like it would be too sluggish and heavy for a 2x4 system. And you loose that feel of the 4x4 drive and on a suv of that size it makes a big difference. But good luck finding it, im sure someone out there has it.

I have had a few different autos with the ability to switch between 2 and 4WD/AWD. The difference in MPG is insiginificant. Like 1/10 or 2/10 th's of a MPG. The savings is so small that the Dealership said it's not worth it to keep it in 2WD. IMO even if you could do it I think you would never make your $ back.

i second that....been many discussions on here about doing that....putting on locking hubs etc....you are still hauling around the same weight so what is the advantage...not spinning a few gears and shafts....the savings in MPG wouldnt be noticable....and besides...if you buy a hummer you arent concerned about gas mileage.
