Here is a LINK to a 4xWire post about the possibility of a Powertrax locker for both the 10 and 12 bolt Zu's! A LOT cheaper than the current choice (okay so at present there is no choice only ARB$$$$$$$$) we have. Front and rear Powertrax would be about the same as one ARB. Of course they are not selectable but would be a nice option for those of us that don't own a bank!
