I have a 79 f150 4x4 with 33x9.50x15 tires There seems to be enough room for 35s but they might rub What size blocks did ford use in the rear stock? I think I might have a 2 inch lift. I dont have a body lift either. My rear locks are close to 3 inches and I think they say ford on the side towards the wheels. So what do you all think I have? I know I either have no lift or 2-3 inches of lift im not real sure.

 

sounds like yours is stock, they came with those 3 inch blocks in the back from the factory can run 33x12.5's on that trucks without a problem, but 35's will rub
