I'm with these guys... if you're only looking for an inch (who isn't?
... at least my wife says I should be) just get a set of torsion bar keys.
They'll probably be cheaper to install (definitely easier) than a bodylift on the H2.
It would take all day to install a bodylift (if one were available) and then you'd have to make brackets to raise the bumpers, etc, etc.
I can install a set of torsion keys in 20 minutes.
.....especially if you're only looking for an inch.
