i am about to put a 6" lift in my 2000 f150 and i was wondaring if 37x12.5 will fit. if not can i put in a 2" levaling kit in to get the extra clarence?

 

no they wont fit
you will have some rubbing with 35s
also your truck has a torsion bar front suspension, if you want a lil more lift on the front you just crank them a little bit
if you installed a 3" body lift on top of the 6" susp you could fit 37s or even 38s

 

i have seen 37" with just a 6" fabtech but they had to crank the torsions all the way and take off his fender flares and do some major trimming, it can be done, but it will fit alot easer with a 6" and a 3 inch body it will look better also. good luck

 

I've seen one person fit 37x12.50's with a 6 inch lift, but he used the OEM wheels.
