5.0 Eaton Dana 44 E-Locker

Excellent quality, the installation was easy and the locker works great!

1.0 No Good

Could never get the locker to work. Replaced the stator magnet, locker still did not function. By then I lost faith in it as far as a product, so I returned it and went with a different brand.

4.0 Well made. Pretty simple installation

This is in the rear D44 of my Jeep. Time will tell how durable it is. The new 4 pinion design appears to be pretty strong... if the magnetic locking assembly holds up, this should be a great locker. One important thing to be aware of is that the locker should only be engaged while stopped or barely rolling. It also will disengage (unlock) briefly when shifting from forward to reverse or vise versa, so be careful on the gas when changing direction.

Q: Hi, I have 2013 Rubicon Dana 44 front axle, will this locker fit? I’m also using RCV shafts. Thanks Answer this question

A: If it is the factory housing it takes a metric locker which Eaton doesn’t offer. It would need the factory locker or the Ox locker: E-locker part number 2007503 or Ox part number: D44-JKR-30

Q: will tis fit the 2020 bronco? Answer this question

A: The 2020 Bronco has the Dana 44 AdvanTEK® solid rear axle with available Spicer® Performa-TraK™ electronic locking differentials. If any of the e-lockers will work, it would most likely be the 19977-010 but we have not been able to confirm this with Spicer yet.
