I also find the way the G80 kicks in at 120 rpm a little mechanically scary but that's the way it's designed. It has me a little worried with my bigger wheels and tires; more mass to come to an abrupt halt adding to the stress on all the components. It would have been better to have electric locker's front and back but this is what we have. I'm very new to this so plan to go play this weekend and test my locker out (16 Colorado Z71).
