HDi shells are sputter bearings, if you look, you'll probably find that the upper shell is a slightly different colour/texture than the lower shell... They're a much better shell, very strong... That's why they're a lot more. They fit fine on XUD9 cranks, however.
Hdi Rods are the same length as XUD ones though...
