the differential itself would come from an 1/8th scale buggy or truck.
e-maxx is considered 1/10th because of the drivetrain difference.
you would need what is considered the standard for 1/8th.
that is like the hotbodies diffs that mike sells in the store.
you need the 3.31 ratio ( those are the non pro ) for e-maxx with transmision or slipperential.
