I seen a green F-150 today with lift kit, We were both driving down the highway. By the time I got up to it, it turned the other way. Could not get a good look at it. It look like it had a 4 inch lift and 37s about 20" or 22" rim. Is that possible 4 inch and 37s. The tires filled the wheel well. I never seen a green f-150 before.

 

not possible, probably a 6", 37's would fill the wheel well of a 6" pretty tight.

 

i'd say it would depend on rim width, i've seen leveled trucks with a body lift running 36" iroks. so its possible i think. but i'm thinking your gonna rub, or being friendly with a sawzall.
