Anyone know the answer to the subject question. I am going with the Rough Country kit when I can get my hands on it.

Anyone have a recommendation on a good high lift jack?

accept would have been the right word, but idk the answer to the question

www.trailduty.com has some nice hi lift jacks

real nice people there too

i've got a 35 BFG MT on mine with no problems
wheel has 4.75 BS, stock is 5.0 BS

It's going to be more a function of the offset of the tire rim you are using that determines it. If they have the same offset as the stock Hummer ones, I would guess another 3 inches width would be OK, just looking at mine and taking a WAG.

Now I like those rims, would you be so kind as to share where you got them

the oiginal RC post said the 37's on stock wheel fit on the back just barely

Those are ProComp 7089.

I know you can get them at 4wheelparts, don't know where else.

yeah,
what sewie said, that's where i got mine, 4WPW
i went with the 17" though, stock are 16"

What is the standard rim size on the H3 with the Adventure package?

16 x 7.5 and here is a pic of a 35" tire 315 / 75 / 16
