How big of a lift kit would I be able to put on my H3 Hummer without having to get drive shaft extensions and all of that other jazz. Also who do you guys reccomend of lifts and what size looks good on a H3?

If you intend to use the vehicle offroad, I prefer using as little lift as needed to fit any given tire size. You can fit up to 35" tires on the H3 with no lift or just leveling the front.

The higher you lift, the higher the center of gravity becomes when offroading (which is bad).
