The adventure package comes as follows:
1) 33" tires
2) 4.56 gear ratio (probbaly due to the larger tire killing the stock gear setup) Plus more offroad ability gearing wise.
3) stiffer suspension and shocks.
4) different (lower) gearing in the transfer case.

I think all H3's have the 4.56 rear end ratio, only the granny gear ratio is different between base and adventure setups.

Better check your build sheet. From what I saw at the dealer, 4.56 gears are found on the Adventure package.

Wrong, read the sheet.
All automatics have 4:56 rear ends (both base and adventure). This chart is showing different gearing of AUTO vs. MANUAL tranny.
