Can you confirm if the Eaton 14234-1 (ELocker Dana 44 / M210 / M220, 32-spline) is compatible with the front axle of a 2026 Jeep Wrangler Unlimited (JLU) Willys 2.0L?The vehicle has:
Front axle: Dana M210 (wide HD tube, open differential)
Rear axle: Dana M220 with factory Elocker
Gear ratio: 4.10 front and rear
It is a Willys (not Sport or Sahara)
I only need confirmation for the front M210.
Yes, that is correct. The Eaton 14234-1 ELocker is fully compatible with the front Dana M210 axle on your 2026 Wrangler JLU Willys. Even though the front axle uses the wide HD M210 housing with an open differential and 32-spline shafts, this locker is designed to drop right in.

Will it fit my Jeep JLU willys 2.0 2026?
No, the EATON 14234-1 Dana 44 Electric Locker will not fit the rear axle of your 2026 Jeep Wrangler JLU Willys 2.0L.
Here is why:
Rear Axle Difference: Non-Rubicon Wrangler JL models—including the Willys trim—come equipped with a Dana M200 (Dana 35 equivalent) rear axle housing using 29-spline axle shafts, rather than a Dana 44 / M220 rear axle.
The Correct Part: For a non-Rubicon JL rear M200 axle, you would need the Eaton 14244-1 Dana 35/M200 Electronic Locker instead.

Will this locker work with the OEM locker switch from Z Automotive?
Yes, the EATON 14234-1 Dana 44 Electric Locker will work with factory-style integration, but not right out of the box using just the bare switch.
Because non-Rubicon models (like your Willys) do not come with factory locker wiring or control circuits from the factory, you need an interface harness to bridge the gap.
To use an OEM-style switch (or the factory dashboard controls if you add a switch bank), you will need a controller harness like the Z Automotive Z-Locker Controller module (or a similar integration harness). This hardware translates the factory switch signal into the 12V power output required to cleanly engage the Eaton ELocker solenoid while keeping your computer free of error codes.

Is this compatible with the Mojave?
The short answer is no, it will not fit. The Jeep Gladiator Mojave features a heavy-duty Dana 44 rear axle (M220) and a Dana 44 front axle (M210). This part number fits the M210.

Will this fit a Gladiator with the diesel engine
Yes, it will. Thanks for your inquiry.

I have the 2018 JL with the M200 rear end. Will this work in the M200?
No. It will fit M210 Front axle or M220 Rear of any gear ratio as long as it is not a Rubicon model. Sorry for the inconvenience.

What M220 is this for? The 32 spline non-Rubicon or the 35 spline Rubicon?
This is for the 32 spline Dana 44 (M210/M220) applications. Thank you for the question.

Is everything in the E loker box for installation of the locker? or do I need to buy a switch and wiring?
The locker will include the wiring harness and switch needed. Thanks for your inquiry.
