Facts about Harrop Eaton ELocker Engagement

We talk through and demonstrate the design and functionality of ELocker - selectable diff locker engagement technology.

You have saved me for not buying a front and rear set. I’ll keep my Truetrac. Thank you!

Harrop, your own video here has made me choose another brand of locker.

PLEASE READ BEFORE BUYING AN E LOCKER.
This video clearly shows the locker unlocking temporarily while Changing direction. This is fine when there's no load but when theres a large amount of load like recovering from being bogged that 6 inches of going from locked to unlocked then back to locked is very similar to engaging the locker while 1 wheel is spinning faster than the other. This exact situation has caused my locker to fail. The car is fully drivable but the locker does not lock in anymore whatsoever. There is proof as each ramp has stress cracks proving the damage was caused while reversing and going forwards which is exactly the situation that occurs when recovering a bogged car from sand. So far Harrop have denied my claim and I am currently fighting this as I never ever engaged the locker unless I was stationary or rolling slowly in a straight line with no throttle.

What’s the misconception on social media?

It takes 6 inches (depending on tire size) to re-activate the locker when shifting directions...

Then 6 inches to re-engage going forwards again.

If you’re just driving through a bog hole it wont make a difference as you point out, but if you are ramped on a steep rockey steep hill and trying to launch over an obstacle its a royal pain, and its very noticeable.

Dont think there are any ‘misconceptions’. Just well informed 4WDers that have used the products and know their limitations.

So this REALLY begs the question, why doesn't the electromagnet just engage/disengage the locking plate, or the pins directly? Is a mechanical, space or patent infringement issue? It sure seems a more practical action that wouldn't have the fw/rr disengagement issue.

Att.Harrop, just wondering what is being done as a follow up to what seems, some less than favourable reviews.

[jojinapigkit]

what harrop e locker should I buy for rear end on 2021 Toyota Hilux conquest? what is the part #?, thanks.

[SLADE]

I want one in my Foton Tunland.
But sadly I will be told it can’t be done.
Apparently the Tunland is supposed to have Dana 44 rear and Dana 35 front.
No one can say for sure.
Surely an existing version can be adapted.

It’s funny how this basically just makes it clear that no one has any misconception about how these operate. The flaw is the fact that they unlock when you change direction. Air lockers or automatic lockers don’t have this problem

[dirtbike]

Damnit. I wanted one of these. However the unlock and relock behavior solidified my decision to not buy one. On the plus side, the coin I save I'll spend on onboard air. I drive stick so sometimes I'll roll backwards before going forward

Good afternoon. Bought a rear axle. I want to buy a front axle for Land Rover Discovery 2 cheaper or from the manufacturer?

[skoda]

excellent. Can I get one for my front pajero 4 2007 3.3 did ?

[rollercuz]

Movement at the centre of the axle is relates to a lot more at the tyre, seeing the movement from the diff centre in this video I can't see it being much more then 6 inches

[lacocheraderubengalland]

I want of this for a Nissan np300 2017, do you know where can i Buy it

Great demonstration. Someone needs to make a rear E- Locker for the Ram HD (Cummins or whatever AAM 11.5). Harrop/Eaton, AAM, Yukon, TJM, or someone needs to step up and make this. It's so overdue. Yes ARB is available but it's not practical. Not to mention the seals that wear out and need to be replaced whether you're using them or not. ARB is good and strong but a flawed design in the actuator, and too much to fiddle with and go wrong. I hope the industry sees what a potential gold mine this is and moves on it soon. I should mention that the Power Wagon rear E-locker is available through Mopar (Only one available for AAM 11.5) and comes in well over $3, 000 U.S. for just the carrier assembly. Screw you too Mopar...

Why does it unlock when changing directions?! I wasn't even looking for this diff but that seems like a huge problem. If your trying to shoot up a rock step and you put it in reverse to get a 6-12 inch run up to bump up over and then both front and rear are unlocked. Then they lock mid bounce when the tires have 20 times the traction it's just asking to break the weakest link, be it your CVs, U joints, and or axle shafts. Looking at this from and engineering standpoint it's ludacris, the amount of shock load created is immense almost like dumping the clutch.

[regularguy]

going to order two soon for my 93 Toyota

[markkuman]

Mighty impressed. Can this product work with Toyota Landcruiser 70 series 2017 model and more recently? Hello from Papua New Guinea!

[superhurricane]

it still locks and unlocks when going forward to reverse. that's all you need to know to know it's not good enough.

[lukerevolution]

There is so much misinformation out there. It's hopeless. Thanks for the demonstration.
