Not that I am aware of. However, Eaton makes an e-locker for the 1970-2012 Dana 44. It's just a matter of time before they come out with one for the newer models.
For anyone wondering what an "elocker" is. It's an electronically controlled rear differential giving the operator the option to lock the differential when they want to, or open it when the power is not needed.
Hope this helps!
