i dont own zilla hubs so kinda hard to make a set. i run z400 hubs/spindles on my bikes.

sorry about that, thought you had a zilla or 250, but i think the z400 hubs are the same, i have a set i'll dig them out and check.  if i remeber right the bearings are the same, so they might have the same size hubs where these would mount.   


why would they be 2 piece?  just want to be more complicated! lol    i still have to drill mounting holes in this one, and you will have to drill and tap the hubs.
