http://www.roughcountry.com/ford_2wd_97-03_f150_3.html if so i want to run 33s on a 16 or 17inch wheel. do you think its possible. i have a 01 screw 5.4

 

umm i wont go more than the recommended tire size (31x10.5) but thats just me. i would run 33's if i thru a 3 inch body lift on it.

 

you can get a 5 1/2" kit off ebay i think for not much more. or a 7 1/2" fabtech for about $1000-$1100. i wouldn't run 33's unless you don't mind a little rubbing. i don't know much about the OBS f150's so im not much help.

 

worst case you think i could run a 16 or a 17 inch wheel in that 31?...

 

i still can't believe you can only run a 31" with a 3" lift. you can run any size rim you want just need to be close to factory specs to get minimal rubbing. if you can find a tire shop who will mount 33's on the rims you want and test and check for rubbing that would be your best bet, but if you seriously want 33's dont settle just because your settled on this lift. choose tire size, then choose the lift that fits what you want.
