well i was in school today taking a final and was reading some older "4wheel and off road" magazines. i came acroos a german made locker from Offrotec, it looks bad ass.. this is what it says: " The Offrotec locker uses a sliding shift fork thats mounted in a new cast-aluminum differential cover. This design is similar to an Ox locer, but unlike the cable-acutated Ox, the Offrotec locker uses a vacuum diaphragm to push and pull the fork to lock and unlock the differential." now that sounds cool! /forums/images/graemlins/smile.gif so has anybody heard of it, or used it? it is in the December 2002 issue. they tested it and said it was amazing, they put it in a dana 60 up front and abused the crap out of it..so anybody ??? thanx guys!
