Ford keys installed on my Z, question about Avalanche

Hi there, I've been watching and reading a bit, but this is my first time to post. About me; 25 year old Kansan, elementary reading specialist, high school coach, hunter, fisherman, general outdoorsy person. About my ride; I have a 2001 Chevy Z-71, 5.3, four door, loaded (everything except the leather, I hate it!) K&N, Hypertech III, flowmaster, I just put the Ford keys on. I had a buddy buy the high dollar aftermarket keys. I did a little research here, bought the ford part, and think they did a fantastic job. I was able to raise my front end a full 2.5 inches, and am now going to put 285's on my truck.

I also have a question.....my brother has an 03 Avalanche and after seeing my truck now, wants his to sit level as well. Can you put the same keys on the Avalanche trucks? I know that they are on a different (suburban) frame, does this make a difference? Thanks in advance for the answers.

just did some more research, looks like everything underneath the Avalanche is the same...more Ford parts to buy for our Chevy's.
