I finally got my Carli ball joints so I'm getting ready to do the DynaTrac/BJ thing. I am thinking of a selectable locker while I have the front apart. I was gonna get the Eaton E-locker but I've been reading that it really takes quite a bit of modification to get the GM 9. 25 locker to fit the Dodge. Don't really want to do that. So what about the ARB unit. I have air already. Anybody with install experience? Are there other options?
