Default Hummer H2 2003 2.5" lift

Hi all, i need your advice guys.
i'm thinking to do a small lift for my H2 2003 trying to keep most of the parts as stock (tiers, air rear suspensions ... etc)
so what lift kit shall i use and how easy to install such a kit.
shall i only lift the front side of the car or both sides ?

any suggestion is highly appreciated.

I did a 2" lift on my H2. I used the chevy 1/2 ton green Keys for the front. Then I had some custom spacers made for the rear air bags. You will also need to modify your rear air suspension ride height sensors. And use a tech2 to reset the ride height. The dealer can do this and they will probubly charge you an hour of labor. Also you are going to need to extend your rear bump stops.

You can go as high as 3" in the front if you want but you are going to need to get into the cognito upper control arms. So you are pretty much limited to 2" of lift in the front with the factory control arms.

Any lifts with air suspension will be very difficult.

Thanks a million HumminNBoatin, very helpful information.
i just need some clarifications:
1- for the rear air bag spacers, what is the good size to do (if i wanna stick with 2" front lift), and are they available online ?

2- what is the level the dealer should set the rear hight level ?

3- sorry i'm new in all technical words here, what do u mean by teach2 ?

Thanks in advanced
