Yes they are standard 1310's unless you have something funny in your jeep. IE dana 60's or rubicon 44's. IF you have rubicon 44's you then have 1330's at the diff and 1310's on the two up next to the t-case.
Just in case you have dana 60's
--- you will have either a 1340 or 1350. 1350 are ford sizes and 1340's are GM Chevy sizes.
