Shop around for some used front springs, probably some 3-4" lift ones. Add a spacer for more lift. For the rear, search Bastard pack, and get some lift shackles. You could do a block, but not reccomended all the time. You can do a RE hack n tap, or a PORC SYE, and run a front shaft in the rear.
If you want to wheel it hard, better carry spares. Axleshafts, DS, TRE's, maybe a hub, along with the other essentials.
What kind of terrain do you wheel hard on?
