I'm bp, they have a factory lift. Came like that stock. As per policy we (bp) are not allowed to modify any suspension aftermarket. I do believe we put the limit s straps on though just to save shocks. It had to come that way from factory. There was a time when the old Bronco's were getting rough country lifts but things were breaking so they stopped it.
But yes, I can assure you that the trucks do AWESOME! The truck you bought had probably been air born more times then you want to know

. They get thrashed because no one cares since its not "their"vehicle. Just go through the steering because 90% of the super duties we had had terrible death wobble. We only have a few left at my station but they are still my favorite to take out. Hope its a good truck to you.
Edit: just saw that you are working on it.
