It just depends on how much money you would like to spend. You can just lower the front end with a torch to the coil springs, or you can replace them with "lowering springs" (preferred method) or you can replace the lower control arms with tubular ones that give you a lower spring mounting point. The rear end you can do with block kits, but you can actually LOSE traction as the geometry of the axle to leaf's change. Usually you would replace the springs with a 3" drop, that would bring it down about 2" in the rear. From there you can drill a new bolt hole in the front leaf bracket 3/4" above the existing one. But while you have the leaf's out, might as well replace the bushings.
