Yes if you upgrade differentials you can't put 28 spline axles into a 31 spline differential lol..
The factory gt 8.8 is just 28 spline
For just a gear swap you don't have to bother with the diff, if you notice the rear end doesn't lock up completely like it should, then look into getting a new clutch pack for it
