The ball joint spacers with a bit longer shocks and a rear with more droop and longer shocks will absorb bumps / landings better because the shocks have more distance to absorb the shock of the landing / bumps. My IFS truck is setup like that and is fun for high speed trails and small jumps. I have a 2" body lift too and 33's fit with no problems. If you run 33's, 4.88 gears will help. 33's with stock gears put the gear ratio a bit high.
