Whats biggest tires i can slap on it do you think? and what do leveling kits and all do... if i wanted a little bit of height added b/c my front sinks lower then the back.. I not sure exactly but dont wanan spend 1000$+ on a lift...

 

A leveling kit does excatly what its name suggests. It levels your truck. It makes the nose set higher so it levels your backend and front end. As for a wheel I wouldn't think much over 16's. I have 15's with bfg radial t/a tires on my 95 2wd and they are just right.
