The Birfs i have are hardend or at least they where 
I think i may get the 30 spliners and be done with it.
Has anyone had problems breaking there free wheelin hubs with the new longs?
Now with the 30 spliners what will happen next me gears may go bang ? or will i blow the detroit no spin locker out? any experiences?
Thanks again guys

all of the above   but you not running a 60 so you have to expect to bust from time to time..But there are more ways to add strength,,drive flanges,,cryo ring and pinion,,cryo hub gears..The detroit will prolly hold up better now with the 30 splines over anything..Detroits usally bust from the shock of broken axles,,I doubt you will bust a 30 splins so not that it won't happen,,but less likey then with a axle that could bust or will bust..
