I got a 2" Body Lift Kit from Travis at RubberDuck 4x4, minus the lift hook extensions. The install took some finagling with a pre-98 truck, since it was really designed for the turbo diesels, but the end result looks great. Much more clearance for my swampers up front in particular, and I will probably step up to 39.5" tires when this set needs to be replaced. I have even toyed with the idea of trimming the front fenders a bit a and trying to see if 42's will fit... but that is another mod to worry about later!
**UPDATE** Installed the 2" Suspension lift, also from Rubberduck4x4 - that brings my total lift to 4"
You can see my full write up on the installation of that lift in theHUMMER Section of OFF-ROAD.COM
I have since had the rear bumper and body mounts modified, to gain additional departure angle clearance, and close up the gap between the body and rear bumper:
