I was in the NW forest in snowy conditions with my AF1150 and being naive...thought that my 4x4 was just that...WOW was I wrong. I didn't know what the difference was between a full floating Dana 60 and locker really was. I'm not so smart right? I was stuck in a really bad place and my front end failed me. I swore I would never have it happen again. When I needed traction it failed, Horribly..badly, scary bad. So a new project has been on my bench.....I already have on board air...this is not the first time I have been in the front end...A total rebuild with Moog everything so I know that Dana 60 now!! The decision was to go with air or electronics. After a lot of mind bending...being the air was already there...OK so what is your take on it?...I wanted a true locker. I'm saying when you need it...you got it, both tires pulling..but it will still float in 4x4 going down the road unlocked.
