An insider with direct knowledge once told me the lockers Jeep use in the Rubicon have been extremely, EXTREMELY reliable over the years. They basically never have warranty or failure issues (unlike, for example, the sway bar disconnect on the JK Rubicon).
That insider told me Jeep are extremely happy with the e-lockers they use. Based on that, why would they change?

They said a lot of the same things about the TJ Rubicon 'Fuji' low pressure air lockers too, and then moved on to the electromagnet 'Eaton' style design.
The JK/JL electric lockers have their quirks. The large electromagnet tends to pick up all the metal flake in the diff oil and concentrate it into the carrier causing some issues over time. The current design uses the same pin-ramp setup as the 2-pinion Eaton Elocker also....generally, this means that the locker 'can' unlock-relock when changing directions on the vehicle if the left and right axle have any bind on them at the time.
There are also pretty well documented issues on the control and sensing inside the diff.
Sorry, the post I made inside the other thread is easily missed and this is too important to a lot of you... so here it is. DOETSCH OFFROAD There are multiple failures that need addressed: -Solenoid sensor fills with oil (causes ground faults) -harness end gets oil in it (causes ground...

If the 'Eaton' design was THAT great, I don't think we would have seen Ford do something different with access to the same product ( they already use versions of it on other axles in their lineup). I don't believe that Jeep owns that design in any way. The fact that Ram is now using the Performatrak diff in the TRX is another indicator that the JK/JL locker design might not be the holy grail for designs. Eaton also has a new aftermarket design that is an improvement over the old version with quicker lockup and no ball-ramp system anymore.
It will be interesting to see what happens if they do go through with the new 'heavy-duty' rear axle for increased tow capacity. My guess is that they will be using something like the Advantek M235 rear axle like in the Bronco Raptor. It would be amazing if they combined that with some of the tech from the Ram TRX M250 rear full float axle, specifically the full float system that uses unit bearings ( similar to the old Jeep Commander design)
