leveling kits or 3 inch body lift that is the question

[stepside83]

i have a 2003 chevy silverado z71 ext cab, its black, it has true dual exhaust (2 pipes 2 mufflers 2 tail pipes) 2 inch blocks in the rear and torsion bars turned up (thats how it was when i bought it) im wanting to put a leveling kit on it and was looking for pics of anyone whos done this also was thinking a 3inch body lift insread so any picks of just a 3inch body lift on a similar truck would be help full as well thanks
