If you mean a locking diff like the eaton rear units, no.
Look up the production codes like I told you in your other post. No one can
tell you if you have a posi-trac or not. It's on the production code label
in your truck.
Write down the whole list of 3 digit alphanumeric codes and do a search on
Google.

It's safe to say that his GM does not have factory front differential
locker as they have never offered a front diff locker.

Are you sure about that? Ford did and they usually follow suit.
