I just need verification on what diff's I have. I think they are 8.8 and 3.31 gears. But the gear ratio number only shows 31, not 3.31. The axle code on the sticker is 27, so that should be a 3.31 non-limited slip.

Please confirm that these are matching diffs and what would have came in the truck. Thanks

 

Yes, I read this as 8.8 with 3:31 gears

 

Yeah, 3.31 open diff. The first 3 is sometimes under the bolt.


EDIT: For some reason the last pic took a while to load. Here's the first 3 right here:
