Which diff do I have?

So I did some reading about ford’s 9.75/8.8/super 8.8 my door sticker has axle code 27 - 3.31 open diff. But what diff do I have? I’m guessing it’s a super 8.8? Are 9.75 & super 8.8 the only diffs found on 21+ f150s?
thanks

You have the super 8.8.

The 8.8 and 9.75 are the two options.
