What is the best 3-4 inch lift kit

[HummerMann]

When I had my Toyos and the 3" lift it wouldn't fit in ANY parking garages, especially the 7 ft ones downtown. That three to four inch number is not exact on the lifts and don't forget to ad the extra height from oversized tires. Hot weather can make your Hummer grow as the steel in the suspension expands. On the coldest days in the winter I could almost fit in the 7 ft garage by the office, but needed about three inches inches to fit (those big tires have a larger sidewall), and on hot days it was slightly worse - something I never factored for. Then you have the gearing issue with oversized tires. You can't put on big tires without changing the gears unless you want dismal acceleration.
