hey 78burb, I am about to lift my 89 suburban 4" and use 33's my self. I have been doing a lot of research on it. I am still looking for a comfortable ride and to use my burb as tow rig, but be capable of having some fun with. So far what I have found doing a shackle flip in the rear and 56" springs up front would yeild the nicest ride. I am also converting my burb over to 4x4 at the same time. Search on my name here and pirate4x4.com to see the results I came up with about lifting my burb. The guys here and their gave me some excelent advice. They also helped send me in directions of other things to search for and learn about. DO not forget to get extended brake lines. I hear people say you don't really need them for 4" of lift, but I think differently. I did have my burb stuck the otherday on a sand burm. (I live in the desert.) Anyway I had the back tires dug down into the sand and the front tires where hanging off at full flex. While I was stuck like that waiting to be pulled out I was checking my front end over. It was after 6' off the ground. Brake lines where not tight but with a 4" lift I think they easily could have been. Just another thing you should research and decide on for your self.
I have foind tons of info on this site for lifting my burb. Do a search on shackle flip, do one on 56" spring conversion and do on eon extended brake lines. You will find tons of info. I will be lifting my burb 4" all with parts from teh donor truck I am going to get my 4x4 parts off of. I have to buy the donoro vehicle for the 4x4 so i figure the lift is free since I will already have the vehicle. The things I will have to pay for. New longer shocks on all 4 corners, extended brake lines. Heavy duty shackles.(just for my piece of mind)
and bald tires.I am stepping up to a 6" next month,I would like to go to 35's but I want to regear for those 1st.I'll do the lift but stick with the 33's for now.33's are great for a daily driver.
... just kidding
