E locker

I have a 2001 tacoma with an 8.4 diff can someone help point me in the right direction for a locking differential preferably a electric locking diff 1

 

A13457 Harrop ELocker (cruiserbrothers.com)

 

Thank you much I been looking for weeks and couldn't find anything

 

It can be rather confusing looking through Toyota parts with all the different variations IE T100, Tundra, Pick Up, Tacoma 5 lug, Tacoma 6 lug e locker 8.0, Tacoma 6 lug open 8.4, 4Runner, etc.

 

just get an airlocker, go to a 4wp and have it installed elsewhere, have on board air and a locker for like 1700$

 

ARB air locker is probably the way to go really.

You can go factory E-locker if you're only planning on doing the rear. But there isn't an OEM independent suspension option version for the front locker.

Not a fan of how the Eaton/Harrop engage and disengage when driving forward and reversing.

Also I like how if the ARB's fail they do so in the open diff state where as E-Lockers will fail in the locked diff state.

I also personally just feel like air is less susceptible to moisture and corrosion.

But thay all depends on your air compressor functioning. I suppose you could get a high pressure tire style bike pump for emergency backup.

 

I'd vote electronic over air.

Air, requires more components though it could be argued that this is good because you now have onboard air. Tell that to some of my friends that have wheeled for years and had their ARB compressor fail.

Air lockers will need servicing, as the seals don't last forever.

I had a large reputable vendor tell me both ARB and Harrop are really nice lockers, and to go with either one. But in the many years in the business, they've had several ARB lockers fail, yet not one Harrop.

For all reasons above, I went Harrop.

 

They're both awesome and expensive, and they both have pluses and minuses. Catastrophic failures are exceptionally rare for either. I would have been ecstatically happy with either after getting stuck several times with open diffs. I chose Harrops more out of curiosity than anything else. My regular cab soulmate @Jiveydude had installed ARB's front and rear and I wanted to conduct a long-term experiment with Harrops on a similar truck.

So far the only problem I've had was one of the pins on the deutsch connector for the rear diff wouldn't stay locked in place so it wasn't getting the current to engage. I discovered the issue not in the middle of nowhere but on my snowy driveway exercising things after my truck had been parked for months. It took a whole 15 minutes and 50 cents in materials to switch both diff harnesses to blade connectors.

Yes, the Harrops disengage for half a turn when changing direction. If that ever results in a donner party scenario that wouldn't have happened with ARB's, I'll be the first to let the good people of Tacomaworld know after I'm done eating my friends and pets.

 

You're a good man.

Pets get eaten last, always.

 

Same here on talking to people in the industry about Harrop. No Harrop failures. I like the simple design. Wiring was easy. I have it set up so I can engage the front separate from the rear. Harrop will cost more. I would rather have a hassle-free locker

 

On the contrary, the requirement for air makes the ARB cost more in the end.

Some of us already have onboard air before investing in a locker as its the most efficient way to aid in traction while going off-road.

Some have co2 (I do), others a Viair or similar (me too), and then some have an ARB but not always mounted to the vehicle.

Love your setup by the way.

 

ARBs have been pretty much the industry standard for generations. Great lockers.

They don't get to be that way for being crap. Pretty much everyone uses them. But that doesn't mean ARBs are still THE best. E-lockers certainly have their advantages, which is one reason the TRD e-lockers are so good, although the Harrop/ARBs have a better/quicker engagement.

That said,another option is finding a donor TRD e-locker and swapping axles (simple bolt-on swap, if you find the same gear ratio). Overall, you'll likely end up cheaper than either a harrop or an ARB, but of course then you're running the risk of used parts, and they may be difficult to find.

 

But 8.4" is bigger than 8"

Some of you need that extra .4

 

Is that what she told you?

 

it's not actually bigger, the ring gear is still 8" OD. It has a different number of mounting bolts and more bearing support though so it is technically stronger

 

I know

You just had to ruin my failed attempt at a joke

 

as far as elocker vs air: I like the ARB in the front. It unlocks and locks instantly.

The factory rear elocker is very finicky. Sometimes I am stuck driving in circles or S turns to get it to lock or unlock.

Compressor is a moot point, I had already invested in an ARB twin for filling up my tires, friends, ex's, and whomever else decided to tag along on a run.

 

Another vote for the Elocker. Don't know where you're located but not a lot of people in the cold advocate for air lockers. Condensation in the lines can freeze. Something to consider

 

No mention of Eaton? Isn’t that what came from the factory?

 

Harrop is an Eaton locker.

And no, not from the factory.
