the hub body itself.
and you can not use the IFS Free Wheeling Hub Lockouts... they use a 30spl and are much larger in DIA.
you'll need to use the IFS Hub Body Wheel bearings, everything else is the same (washers, 54?mm nuts, etc)
and $250 seems way too high for a price.
if you want some and dont want to pay as much.... let me know. I may be able to snag some for you.
