ive got an 04 ext cab z71 that im thinkin about puttin a suspension lift on. what are some good brands to go with. im lookin somewhere between 4-6 inches. also any pics??

Might want to look at Rancho or Tough country see what they have and then go from there.

If you are looking for 4" it is more limited. But we have had excellent experiences with Cognito, BDS, Rancho in the 6" ...really depends on your budget and what you are trying to accomplish. Each lift manufacturer has their strong points. Let me know if you need some guidance.
