if you dont wheel/offroad it, then you need a minimum 2" budget boost...if you wheel it, then you should do a 3" suspension lift and 1" body lift...you'll also need to adjust your steering stops in order not to rub when you turn if you've got stock wheels. You could also run a 1" spacer on the stock rims. If the rims arent stock, then you should be ok with the backspacing.
