I have used the E locker in the past and have nothing good to say about it in a Dana 60. Its a limited slip/ and locker. Good idea, bad execution... I have heard good things about the Auburn Ected (sp). Not sure if it is still available though. I believe it goes from limited slip to 95% locked. one wire, one switch, Simple magnet. Arb's are great lockers, But I feel like you would end up leaving it locked half the time. It kinda sucks when you have to plan to do something stupid... And they don't hold up too long when you crashlock them. (lock in with tires spinning).
