ARB Air Locker Comparison

ARB Compare the genuine Australian made ARB Air Locker with a cheap Chinese copy

[ARBxAccessories]

Hi Pauly, the figures you've stated are actually incorrect. It's not possible to state a percentage figure difference between the products as the failure point of the ARB Air Locker is not known because the axle failed prior to the Air Locker, unlike the copy we tested.

The point of the video was to demonstrate that with an Air Locker installed, the axle will fail before the locker, which is easier and less expensive to repair/replace.

Hope that clears things up

To answer the second part of your question, installing an ARB locker generally offers a strength improvement for your whole ring and pinion set (pinion gear and crown wheel). It is much more resistant to allowing the ring gear to flex away from the pinion and therefore it keeps your ring and pinion teeth meshing correctly where your factory differential may let the teeth mesh stray from the flex and form highly stressed zones, which could potentially cause a breakage.

Hi Chris, bits of broken axle shafts are capable of causing damage to wheel bearings, diff bearings, pinion bearings, ring and pinion sets, oil seals (wheel and pinion), as well as the internals of an Air Locker if they manage to get inside. This goes for broken ring and pinion teeth also. For this reason it's advisable to replace broken internals ASAP. ARB employ the strongest drain plug magnet on the market for our diff covers, and they can literally draw the broken bits out of the diff oil.

Wherever possible we test with the strongest available axle shafts that we can find. These can be chromoly or chrome vanadium or nickel alloy, etc.

We have found no directly dependable correlation between axle material composition and torque failure results.

The quality of the material, design of the shaft, machining processes, heat treatment processes and surface processes all play a part in determining the strength of any shaft.

@q8yba7t We're assuming you are talking about a LandCruiser with a centre diff lock. This matter is covered in great detail on the Ask ARB page of ARB's website.

I just ordered a front and rear ARB locker for my Jeep... can't wait to get them installed.

Hi Chris, I've had our Air Locker engineers have a look at the video and this breakage isn't related to the Air Locker. Unfortunately though, given the limited detail, it's impossible to diagnose the specific cause.

[suzukisport]

ARB is the way to go. We are using them in comps they are by far the strongest and it is alot easier to change and axle than the diff.

[mgp-bct]

Did you guys test I against ( OX Locker )

[asdfou]

So... the thing survives up to within 500 footpounds of twisting the axle off of it.
That sounds like a VERY successful test.

[Ralphypwns]

do u no if u can get them on a older 89 hilux? and would it cost more?

[chrislcful]

is it possible when the hemi-shaft brake, the small broken pieces to remain inside to the mechanism of the arb locker and destroy it? or the gears of the arb locker are unbreakable?

is it true or false that when installing arb locker, this protect the pinion gear and destroy only the crown?

[ilynchy]

how much do lockers cost installed and if u dont get dual do u get front or back done ?

[mog]

after this video i would clearly choose the chinese air locker!
why!? because the arb test is bs! the axle shaft on the arb was an aftermarket unit and the other one was an oem shaft (you can see it in the video), also most of the time the arb breaks before the shaft breaks. i got an rack full of broken arbs, and the next thing is 90% of the time the arb leaks air! the worst arb is the ford 9" unit !

[moabman]

The music is annoying. I like ARB's products. I have used my locker here and their over the years. Its starting to stick engaged though. I hope I don't have to take it apart again.

I already have a Powertrax Lock Right locker in my rear axle as of now though if it ever goes out i will be looking for something a little better and I see this. My question is does ARB make this Air locker for a 1997 Chevy Silverado K1500 5.7L with a GM 8.5" rear axle?

[patrick]

my arb air locker failed the bolts snapped before the any drive shaft failed on a front isuzu vehicross quite disappointed putting a temporary Axel in until it is fixed or replaced yet to inspect inner diff, busy getting the vehicle back on the road will be trying to contact arb soon 22/12/11

[muhamedshafee]

the question you should ask urself

exactly how much pressure or strain you have to put on your vehicle to gain 6412ft or 6929ft....
you have to been really driving like a maniac up a rocky surface, wheel spinning on tar  to gain that much strain....any stats or comments?

[ARBxAccessories]

@sierraduke we've heard this rumour too and I'm happy to say that it's totally incorrect. ARB Air Lockers are, and always have been, made in Australia using Australian parts. We've never setup production facilities in China or commissioned any Chinese companies to manufacture Air Lockers. Hope that clears things up.

[chrislcful]

so.. can you explain why happened this ? watch the video (rear broken 8" crown w(arb locker)
is it a bad adjustment (between pinion and crown wheel) from the engineer?
is it normal to brake the teeth from the crown but not in a sequence? as you ll see some are ok, then some are broken, next again ok, etc..also some of them are broken to the inner side and others to the outer surface...
thanks for your immediate reply
