On my old 94 2wd ex cab I used 2" front lift springs and shackles in the rear, i was able to clear 33x 9.5's after i spaced the front bumper out about 3/4". I didn't have any problems after i spaced the bumper out. It was all cheep and the skinny tires worked out great on the truck too, felt really cool going fast around bends too lol.
