What is the best 3-4 inch lift kit

[jsbihn]

Mud,
I am trying to run the widest and tallest tire I can fit on a stock diameter wheel (please note: I didnt say stock width since I will be staying stock diameter but going as wide as I can with a aftermarket wheel)

LoJac and Bimmer,
Where would be the best place I can find these and for the cheapest price?
Also would they still allow my air ride to work?
And what would you say the difficulty level is on install, since I have alot of knowledge under my belt on car work but currently my tool set isnt what it should be (all my tools where disappered on me )

NJ H2,
If my math and measurements are right, the H2 with air right fully inflated measures about 6'9" and if you give it 3-4 inches that is 7' - 7'1"
sure it is close, but usually garages say 7 feet and there is about an inch or two more of clearance. So.......
