Have any of you tried any slow speed crawling with the QE diff? The Visco-lok is speed sensitive so at slow crawling speeds it doesn't lock up until revved to spin the front faster. In Moab I have video of mine taking 10-15 revolutions to lock at slower speeds. Does the QE fix this? Will it lock in sooner at slow speeds? I noticed that the XP's were locking almost instantly even at super slow speeds. Any help would be great.
