Set of wheels for $80? god damn...
Also, all that lift in the front end is going to absolutely destroy your alignment... You will probably need drop brackets AND new camber bushings to be able to get it anywhere near spec.
If it is a bush-only truck, that could be lived with for a short while, but if you are driving the truck daily, your going to chew through your tires in like a month.
And yeah, for cheap lift, I would definately say Add-a-leafs are a decent option. Also, the F150 coils are going to be really stiff, using a lifted coil for a Jeep XJ will give you much better articulation (can get cheapish ones for around $100 online)
