There are several options...A Superlift 4" lift is good for 33" tires. It uses drop brackets to lift your suspension, but leaves your truck's torsion bars at the same place as stock. It gives you bigger tires and a beefier suspension. Third the RCD lift gives your truck a 5" lift in the front and 3" in the back. This is the best lift for a Ranger and of course the most expenisive. It totally replaces the torsion bar suspension with awesome coil springs and replaces the back suspension with bigger shackles. This lift gives you bigger tires, a sweet beefier suspension, and a total replacement of the crappy IMO torsion bar suspension. The body lift will run you about $300, the superlift $1400, and the RCD over $2000.
Also the camburg lift that gives alot of wheel travel and replaces the torsion bars much like the RCD lift. However, of course it costs even more than the RCD. Lastly, if you want a monster truck Ranger you can take the whole front end you truck out and do a solid axle swap. Most put like a dana 40 or bigger in the front. Then add locking hubs, all new steering, shocks, struts, haha everything lol. This is the best lift of all adding as much lift as you want and also doing the same in the back to lift it too with blocks, lifting leaf springs, etc. However all together could be even more expensive than the camburg.
