Nope, you must reuse yours or order new ones from ford. I ordered new ones, but they didn't fit nearly as well as the stockers. They are just lightly pressfit on. The superiors also come with new axle bearings JFYI. I have them in my car and so far so good, but I don't have a lot of miles on them yet and only 7 passes.
My Strange 31 Splines didn't come with the sensor wheel either. One came off my stockers easily and I reused it, and the other cracked, and I replaced it with a new one from Ford.
