Greetings, I'm in the market for an E-locker for my 2016 LC200. According to a webstore, an eaton EAT14213-1 Unit is compatible. Another webstore quoted me a harrop unit HARA9574. Will either of these work with the stock axle shaft housing on the 16' ? What other parts would I need besides a bearing kit?

the Eaton 14213 is the new E-locker4 design, so doesn't not engage/disengage when changing directions like the older/Harrop design. I have one sitting in my garage ready for install when my new LC arrives. I believe a new 32 spline yoke is required, but don't think anything else is different. Touch base with Nitro gears and they can guide you through the parts list.
Just curious. Why an e locker? Those harrops are expensive. The way they engage with the bearings means if you roll back a bit they disengage. Also takes a bit of roll to engage as well. For the price if you went with air lockers the price difference would cover the compressor. Two birds one stone same price range. You have an onboard compressor and air lockers when your done.

I had ARB's on my last vehicle. Happy with them, but was interested in giving the new Elocker design a try. Pricing is not much different than the ARBs from my experience. The new e-locker4 design does not have the bearings and therefore does not engage/disengage like the previous design. This new design just came out earlier this year.
I will still be running the ARB twin compressor, but just for on-board air.

Huh. They redesigned them? Curious. I'll take a look. Thanks for the info. Can't help with the technical info but would love to hear a real world follow up when you have them installed.
I'm very curious about this. Please take a pic if you can!
I looked into this earlier this year right as the new Eaton LC fitment came out. What I found, talking to the Eaton engineer, is that the new Eaton part is actually largely the same, if not exactly the same design as the current Harrop. Just with US distribution and branding (which is a great thing for warranty and such). Harrop's design is actually licensed from Eaton originally. The Eaton can be found a tad cheaper without the import overhead.
I was also excited about the new positive locking design, known as the Elocker4 "direct acting" mechanism. As I understand it, it's only available for larger Dana 60 and 70 applications. Not available for the LC.
I do hope I'm wrong though! Looking forward to your findings.

I will certainly report out once I get them installed later in January. From talking with Just Differentials and reading the Eaton site, this new design does not experience the engage/disengagement. And they added the Land Cruiser application for the Elocker4 earlier this year. Hopefully it works out as stated. 
Oh, I pulled my unit out of the box just now and it is only stamped with Eaton. No reference to Harrop anywhere on it.

I was quoted 1125 for an eaton unit. An arb is 125 dollars less, and an air locker has more parts in it's system to fail. O-rings, air lines, solenoid valves, the compressor itself, adequate line pressure. All an e-locker needs is proper current.

Cool, what year is your land cruiser, and what model # eatons did you get?I will certainly report out once I get them installed later in January. From talking with Just Differentials and reading the Eaton site, this new design does not experience the engage/disengagement. And they added the Land Cruiser application for the Elocker4 earlier this year. Hopefully it works out as stated.

Thanks for the pic.
Hate to break it to you, but that is still the original Eaton ramp pin based design that Harrop licenses. The exterior visible ramp and pins give that away.
Personally, I don't think there's as much issue to the locking/unlocking as its been made out to be. When in drive, it locks in less than 1/10 of a turn differential if that.
The newest Eaton4 design has rods but they are internal. I could very well be wrong and the differences could be internal but I did do quite a bit of research.

Perfect....Errr I will reach out to Just Differentials and clarify. Definitely want the correct information being shared. Thank you for your help.
Yep Proper current. This is only a personal preference. I do not like "current". I do not like air suspension. I wish I could step outside and lock the hubs. This is just me. The electronic part of an air locker is very simple to repair. I have never ever scene some one loose an air locker from a broken airline. In fact the air lockers are less engineered. Less parts. (poor install is 95% of the problems from air lockers)
I am assuming if someone is doing lockers they are doing both the front and rear. The 125$ difference x 2 is the price of a basic compressor that will run the lockers and pump a tyre. Drop another 200$ and you have a very good compressor. Also the air lockers are time tested. Tech is cool but it tends to break.

Tech note for 16+ 200s on re-gearing :
I wonder what the toyota part # is for the dropout housing they're referring to
- *2016 & Newer 200 Series and LX570 equipped with an 8 speed Automatic Transmission will also require an older type Dropout Housing USEDOTLC and Pinion Flange YOKT60060 , and the appropriate offset front carrier or locker NC-T9R-COM or RD151.

Yep - I’ve had ARB Airlockers front and rear on my 2000 LR Disco II for 20 years. Just about the only mechanical item that hasn’t had an issue. Been considering them for the 200.
As soon as gears get off back order I’ll be doing gears and lockers, very curious about this. I’m leaning air lockers at the moment, especially with having a compressor already mounted.

Greetings all. I forgot I posted this a while back. I'm currently running 4.30 gears in my 16+ with harrop E-lockers. I'm running a rear from an LX470 and a front clamshell from a 4.7 liter tundra. I purchased the differentials used and shipped them out to gearinstalls.com with the appropriate harrop lockers.
