\'Fozzy\' lockers and 4 X-Gears in the differential.
I've researched the 'Fozzy' locker thing. This trick involves running two weld beads, 180 degrees apart on the differential side gears. This allows each of the side gears to rotate '100 and some degrees' relative to each other before it 'locks'. This play allows the differential to remain open on large radius turns, and improves driveability as compared to a welded diff or spool. It also allows the front hubs to be locked and unlocked without binding, according to what I read. It sounds cool! Except it won't work well with four X-gears, like the older Samurai, will it? If you have two X-gears, like the newer Sammy or a Heep, you get the full 100 plus degrees before the lock-up. With four X-gears, you'd get half or less than half as much differential action before the welds on the side gears hit the X-gears. Does this sound right?
