Quick question about stock vs aftermarket E-lockers

So I’ve been researching e-lockers and it seems that the big compromise that they have is that they disengage when you go in reverse or more likely slip backwards. I was wondering if the stock e-lockers had the same issue and if there are any aftermarket e lockers that have fixed this issue.

What are you basing this on. Do you run them or even ever had them.

But have you run them or any other lockers ?
I only ask because of some of the questions you have asked in other post make it sound like you have limited or no off road experience.
Those look new in the box

ARB air lockers..,.replace the cheap plastic lines with stainless and regulate line pressures....been solid for 5 yrs and they lock instantly with zero leaks...

I have never had a arb locker leak or fail in any way.

Give them 10 to 15 years, you will be pulling the 3rds to replace seals, it's a well documented problem with the ARB's.

The Detroit is not good for snow or ice covered roads.

100% correct

The Detroit in my 91 would make the rear end slide off the road in any kind of slippery off camber situation. Ie snow, ice and mud.

Other than that I had no complaints.

Honestly in our wheeling group I am the only one running OEM lockers a few guy have spools the rest run ARB and just about every trip out someone is having issues with there ARBs

I've heard that a lot. But I worked at a offroad shop for over 10 years. We would install lockers including ARBs, I have had the front ARB in my fj40 for a long time. I can't recall ever seeing the issue personally. Maybe something is done wrong on installation? I've had a lot of mechanical issues on my fj40. But the ARB just does its thing.

My experience is (thus far) wildly uneven; things I've done, I've done. Other things I've researched to death, been in rigs that already have them (or competing products), etc. Still other things I'm fairly clueless about; should be doing my first new suspension shortly, so asking questions on that b/c a lotta folks here have done that multiple times. When there's something I feel I know enough about, I'll answer others' questions.

That said, I like the HE's performance, and have never seen anyone have problems running them, or really even complain about them. Stock lockers work, but IMO (and I'm not alone on this) HE's are better and faster. From what I've seen and heard, ARBs have oil leakage/spray issues--though someone here said if you run them below the suggested pressure, that goes away. Could be; I don't know. I've also seen multiple references to cold-weather problems. ARBs require a working compressor and multiple air lines; not a big deal for most, but adding complexity is not a point in their favor. Detroit Lockers / TrueTracs I left when I left Fords, back in the 90s; they were an improvement over stock.

Can well-maintained ARBs perform as well as Harrop Eatons under some conditions? Maybe. All conditions? Depends on who you ask. Can they perform better? Nope--and neither can stock lockers. Not sure anyone would disagree with that, and in fact this was discussed somewhere recently.

As to the photo, they are new in the box. ("Do you run them or even ever had them." was the original question.) After researching and riding in rigs that use them, I put my money where my mouth is. :)

The guy who owns sand hollow offroad and owned moab 4x4 for years told me he saw the issue all the time. According to him the arb seal housing would even become corroded on a lot of the lockers and new seals wouldn't fix the issue.

Fair enough :)
Honest question can they be manually locked or unlocked ? I know the ARB can't and default to open when they lose air.
OEM can
Oh, l think OEM e locker is every bit as good as the Harrpo or the ARB, locked is locked and in 7 years of hard wheeling my 80 they have never failed me and they have 275k miles on them.
And I paid less for the 80 then those two boxs.

Oh OK that makes sense. If the the housing is getting corroded that would do it. Maybe people aren't extending they're breathers and let water sit in the housing.

Idk what is causing the corrosion. On my rig the breathers were extended and the seal housings were not corroded. But my seals were toast, that being said the lockers had been in my rig for 13 years. That's plenty of time for an o-ring to give up the ghost.

Oh OK. Well as far as water, I still sometimes get water in gear oil even with my extended breathers. I think it's possible water gets past axle seals. They are really only supposed to keep fluid from spilling out. Just a theory.

Default is open; switches provide power to activate the electromagnets. Switch on and they stay that way until switched off, when they deactivate. (They might disengage for a moment if you back up.) Some folks use toggle switches etc. to prevent accidental switching by human or dog.

As to ARBs, Georg @orangefj45 (or maybe it was Ward @wardharris) has posted before about issues with those (and the lack of issues with HE's), and I for one am prepared to accept their testimony, as they've doubtless forgotten more about locker installs and maintenance than I'll ever know. A few of their posts my research turned up...

That all great but doesn't answer the question.
If there a problem with the switch, wires, locker ECU or actuator with a OEM locker and your miles from civilization on a tough trail you can manually lock a OEM locker with just a few tools. then when you get back to the road you can manually unlock to drive on the road.

In my book that a huge plus and a big win for OEM lockers.

My guess is that with a Harrpo if theirs a issue with the switches, wiring, relay, electromagnets or any part of the system it will default to open and theirs no way to manually lock it.
Same with the ARB

That SUCKS 🤷‍♂️ JMO

I don't have any experience with factory lockers, but I suspect if I had them I'd use them. I knew I wanted ARBs and that's what I run. The three issues I've run into with the ARBs are

1) oil spray makes a mess but vivid fixed that as there are plenty of masks lying around which I now use as a oil trap.
2) there was a a small air leak at the solenoid so the compressor ran too much at elevation. This never impacted the functioning of the locker, but was annoying. Easy fix
3) out if the box you can't lock just the front, but that is a single wire jumper which is easy enough to do.

In terms operability, I've never had an issue.

I have found my Harrops to be very reliable. No issues.

Ah, okay. Good Q. If it fails, it doesn't have power. Old-School hotwire; bypass everything would be my *guess.* Cut the bypass when you hit the road again.

All good but what if it's the electromagnets that has a issue ?
Also I don't like the idea of the locker unlocking when you back up. 🤷‍♂️
