8.25 gears in a 8.75

The gears in a 8-3/4 are 1/2" larger diameter and the differential is beefier than the parts in a 8-1/4. If you put the 8-1/4 parts in an 8-3/4 carrier (which would be extremely difficult and costly as already pointed out) you would weaken it to the level of the 8-1/4 so the ONLY thing you'd gain is it'd look like an 8-3/4 rear


Well I have no clue how he did it, but I was thinking ( which may be way off ), but that the 8.25 gears were some how matted to the 8.75s diff so that the axles would still be 8.75 axles. All in all, I have never been in a 8.25 of had one for that matter, so I'm only guessing . You are correct though. Even if they machined it the way I just said. It is still only as strong as the 8.25 pinion.
