What Diff 2019 1500 LD RPO G80 with 3.43 gears?

[JOEYODR]

What size diff is this? It has 12 bolts on the cover but I’m reading it’s not a 12 bolt?

 

Sorry, this is my first Chevy.

I thought the size was on tge RPO list. Sort of like G87 is 8.5" ring gear

  or G89 is 7.5" 

But it sure is pretty in your picture.  Nice and new looking.

Thanks Rav, I don’t see anything like that on the build sheet GM sent me. I’ll paste  what I have below.

It's still a 12 bolt. I believe it's a 9.5 in the 5.3's and a 9.75 with a 6.2.

[rlcole321]

Looks like someone replaced the original diff., it doesn't look like a locker to me.

[JOEYODR]

Thought the same thing at first but came to the conclusion what is visible is most likely just the back side of the locker assy.
 

 I didn’t have the wheels off the ground when I had the cover off so I didn’t spin it.
