If I were you I'd take my time and do it right the first time. I'd get the air locker first 'cause I figure you are wanting capability. Then, I'd save my pennies for the bumper.

Are you re-geared? You'll want to do that when the locker is installed so you can save labor on one diff.

If you only have a little bit of cash though, maybe the bumper for now.
