i have the 30 splines/diamond/locker setup. i have the front range/ARP studs for the hub and high steer but have yet to install the hub studs till i get the chromo gears. i'd rather replace the studs or the hub body than a chromo birf.
and yes the warenty(sp) does not cover striped splines due to stock hub gears breaking. you'd have to call bobby for an explaination.
