2018 3rd gen lockers

Has anyone tried a 2nd gen locker to see if it fits the 3rd gen? Or which locker have you installed and which do you like best?

Update: this is for a daily driver with a little offroad fun.

 

Same diff on anything that isn't an OR/Pro or MT truck. No experience, have OR locker and it works as intended.

 

I’d go with an aftermarket like arb etc. Someone remind me what the other good one is. Starts with an “H” iirc.

Benefit of aftermarket is anytime locker (though not sure how the trac system etc will like it), and the ARB is really tough. Plus you’ll have OBA.
