Ford SuperCrew trucks came with several different lug patterns and several different lug-stud diameters and pitches. Our truck has a 5x135mm lug pattern, which matched the new SSBC hub bearings. But as you can see, the supplied hubs came with 12mm studs and our truck is equipped with 14x2.0mm studs. Keeping the stronger stds meant knocking out the new 12mm studs in the hub and knocking the larger 14x2.0mm studs into the SSBC hubs. This took some extra time, but it wasn't difficult to do.
