[FGHT ON]

First and foremost look at the wheel you are considering and the backspacing. I know people on here run 37s with no lift and it depends on your exact H2 (all ride a bit different) but there is no way with the backspacing on the rockstar that I could even come close to running 37s or 13.5 with out some lift or considerably altering the torsion bars (think long and hard before you start cranking on them, it changes things). As I currently sit (stock ride height) I rub when I turn hard if the surface is not 100% level. Also, I am a clean freak and the littlest bit or water on the road covers the side of the truck. Hopefully that helps you make a decision.
