well, i do know that late 70's blazers and up are about 2.5-3 inches taller than the early blazers, however, i don't know if that is a body or suspension lift (not that it matters).

I'm not adverse to raising the suspension, but if i can fit the bigger tires without the suspension lift, than i would rather do that.

btw, this truck's offroading use i would categorize as light. The most offroading it will do is a ranch and a few rough mountain roads. nothing serious imo.
