I'm not super familier with torsion bar lifts for these trucks, but I believe they run up around the cost of $2,000 and more for a 4" suspension lift. You can get about 2" in the front if you crank your torsion bars and that is free, but recommended to get an alignment afterwards. A body lift is cheap and relatively easy install. A good body lift kit cost around $200 if I am not mistaken.
