The specs in that PDF are for each component, not for each assembly like you see posted on the door sticker. 6200# is the rating as configured for Ford. While some versions of the Sterling 10.5" go higher, that is absolutely the rating for that exact axle. The F250 version of that axle has smaller axle shafts and less splines than the F350 version.
Also incorrect. They are identical and have the same diameter and number of splines. See above. The higher spline count and larger diameter is a very well known misprint in Ford's tech literature. It's been discussed ad nausem on the forums and debunked by anyone who has taken the time to compare the part numbers between the two.
