Ya you can do a bodylift yourself or with the help of a friend. $213 for the kit that includes pretty much everything you need. Even comes with instructions.
There's a wealth of information on ranger body lifts on this site, just search. Search torsion bar crank too, you might wanna do that, it's free. Body lift will give you 3" extra clearance for tires and a torsion bar crank will give you +/- 2" in the front. Should be lots of room for 33's. This is what I'm planning to do in the spring.
