33s you can get away with. The optimal gearing is 4.56, but if you have 3.73s that fine (Im running 3.73 w/ 33s 5speed 4.0) you may want to look at chromolly shafts $250-300 w/o c-clip elim. Just so you will be less likely to break an axle.
You said you have a 2" lift... add a 1.25 body lift and a 1" motor mount lift and you can run 33s without rubbing your fenders off.
Also you'll need new rims with less backspacing or wheel spacers, Im running 3.75" backspacing, stock rims are usually 5-5.5" backspacing.
