31 spline 8.8
 

Is the ford motorsports 31 spline differential the same as the ones in explorers and f-150s or is it a better quality. They seem to go for a lot more money but they look the same.

Are you talking about the carrier unit? If so, Im not sure there's much difference, the good ol truck carrier should very well do it.

Yeah the carrier. I think some were 6 clutch and some were 8 clutch and some had a 3/4" pin and some had 7/8".
