anyone used this combo? any thoughts?

How else would steering brakes work if the diff wasnt open? It will work but a ARB or other selectable locker would be better cause you can have full traction when you want it and be able to use your steering brakes too.

There was a thread about this a few months ago. I have the ability to lock both rear tires, and pivot that way. Lance as well as a few others said that they noticed that the steering brake/open diff combo is easier to use, but does not pivot as shrply because the outside tire can still turn.
