Which kit did you go with? I searched, but haven't found much on the forum for leveling kits. Any problems? Bump steer? Rattles or wandering? I'm picking up an 18 F350 CC SRW Long box and I will definitely want to level it before I put new tires on. I'm leaning toward the BDS 2" kit with an adjustable track bar. I like the track bar offered from BD Diesel better but it doesn't sat that it will fit 17 up.
