i tightend on mine to get 16in of ground clearnce with 33's. there is about 1 1/2 inch left on the tbar bolts i could tighten on but no need to i got it where i want it. its pretty crazy how much you can tighten on them i knew a guy that took a impact and ran them all the way up and put lift blocks in the rear and ran 35's. i would not recomend that b/c you can snap ur t bars with them that tight doing jumps and what not. 6in rancho is what im going to go with sometime this year. /forums/images/graemlins/truck.gif /forums/images/graemlins/usaflag.gifwww.zombieoffroading.8m.net
