I've got a 1974 K5. I am planning to run 37's or 38's on my 4" suspension lift with some fender cutting. I keep getting conflicting reports as well as downright insults telling me i'm stupid for wanting to run that setup. I guess they don't understand the whole center of gravity argument. Especially since I don't have my cage installed yet, I don't want to role the truck if i'm running w/out the top. So if you have only 4" of lift, tell me what you got!
