Anyone here every uses these?

Hummer Lift Kit, Hummer Suspension Leveling Kit

I am looking to raise my truck a couple inches and found these Readylift kits. They make a leveling kit for the front, and a kit for the rear to raise the back 1 to 1.5 inches. I did some searching on the forum and see lots of discussions with the H3's but not the H2's.

Installation looks pretty easy and the kits are pretty inexpensive. Does anyone here have any input? Should I be looking at something else? Again I am looking to gain a couple inches as I still want to be able to fit in my garage.

Thanks
