Looking at the lift & tire combo thread I noticed 1Ton brought up a good question. Just how much lift is advisable. I've heard so many people say the longbed trucks & subs need more lift than the Blazer's do. At least a 6" minimum for long wheelbase while K5's need a minimum 4" lift for moderate trails. Longbeds & Subs vs Blazers. When are you crossing the threshold from practical to impractical in terms of COG and trail running. What are some safe lift numbers and rim tire combos? I'd like to hear from some of the experienced people if you have a minute. Don't suppose we could suck Marv into this one?
