Rear end slection.
Not the best picture, but they also have a white tag on the passenger side with 9.75 printed on it.
Not always true. My 19 2.7 has the E locker 3.73 8.8. Despite not having a tow package or payload package, it still got the HD frame though so who knows these days what gets what.
In preparation for ordering a 2.7 with a 3.73 locking I wanted to see examples; found a bunch of XLs on the lot without tow packages, payload packages, etc. but with locking 3.73s in 8.8s. Though moment to moment anything can change in production, I guess.






, since my 3.5EB truck (and several others) has it with 3.55 gears.
