My 2000 z71 is equipped w/ the factory locking diff (or whatever they call it), I assume this one will peform about the same way? It doesn't really work all that well, but it' better than an open diff.

Same exact design as the one in your Silverado.

The 14 bolt rear I put in my '88 came with one. I hate it. I should have known better (from previous experience) & took it out. But I thought in a 6000lb+ truck it would behave decent, especially since I never drive it in deep mud or bad weather. Grass or loose gravel makes it chatter and wheelhop, no mater if you sissy- foot it or floor it.

The Detroit Locker in my '72 is very mild- mannered in comparison. I never thought of a DL as smooth- but in this comparison...
