Help identify rear end part

Hi everyone,

I have a 2011 Chevy Silverado LT 1500 4X4. I'm needing help identifying the name of a part in my rear end.

Do you by any chance have aftermarket parts in there, or did a previous owner install aftermarket parts?

It looks like it might be part of an aftermarket limited slip differential in there. It sure isn't a factory part that I'm familiar with.....

Either that, or it's a custom made part that someone macguyver'd up for some reason.

Actually, at the time I posted this last night I didnt have a pic of the actual part but I found this pic online and thought it looked like it so I posted it instead. Today I have a pic of the actual part. It's shaped like the capital letter I (eye).

and it came out of here...

My boyfriend bought the truck last year from a Car dealership so not sure what would have been done to it before he bought it.

Looks like the gov lock posi unit broke.

Can you take a pic of the other side of the carrier?

Does the rpo codes say G80?

I was thinking it is part #11 in the pic above.

At any rate, your differential is toast. Many damaged and broken parts in there.

I'd suggest putting in a Detroit truetrac if you want a posi on the back, or just buy a new open differential if you want an open rear end.
