8" and 8.8" Differential Parts Interchange?

1193 Views 4 Replies 5 Participants Last post by  AKBray907
I have an 8" Dif with 2.79 gears and an AOD trans... way to high a final ratio. I was looking for a replacement ring and pinion, went to Summit Racing, and saw that the part# was identical for both the 8" and 8.8" ring and pinion!

Anyone know if these two use the same ring and pinion (or is this a typo) and IF they are the same, is the carrie interchangable as well ( I have access to an 8.8 ring and pinion and posi unit)..??

The low numberical 8" axle gears were 2.80:1 - 28 teeth to 10 teeth. When I replaced my ring and pinion about a year ago no one was selling anything lower than 3.00:1 so I don't know what you are seeing at Summit (which is where I bought my gears).

No, I am pretty sure the gear sets for those two axles would be different.

Not absolutely nothing, they do share the same pinion nut!

The only thing the same is the pinion flange nut
