nice selection man! and E-locker stands for a electronic locker, it remains a open diff till you flip the electrical switch and it sends a charge to the differential to make it a fully locked differential. just make sure you unlock it before you get back on asphalt!
the only locker that would eat up tires is a spool. all the others are made to either disengage or provide some amount of slip when making a turn.
no, detroit and the eaton tru-trac are complete lockers but allow the diff to unlock and make a turn without eating tires.
Yah thats what i thought, i watched a video on the richmond one. This is the one i was looking into, i think guy explains it pretty well Lock Right Locker - Part 1: How it works [HD] - YouTube
