When I was off-roading with some friends(obviously not in my teg) we got on the topic of air lockers. I dont think these guys know much about automobiles in general. But I was wondering what exactly an air locker does(does it force an open differential to act like a LSD through pressure?) and if anyone has ever heard of one used from a performance aspect? I know the ones I have read about are usually about the same price or > then a nice LSD but I'm kinda curious.
