Hi 57Cusso, an Air Locker is a cross axle diff lock, distributing an equal amount of drive to the left and right hand wheels on an axle, whereas a centre diff lock distributes an equal amount of drive to the front and rear axles. Air Lockers can be engaged with the centre diff unlocked but to get the most out of your vehicle and to ensure an even distribution of drive to the front and rear axles, it's always a good idea to lock the centre diff in tricky off road situations.

Hi Fulsingh, you should only ever use a locked cross axle differential on surfaces which allow wheel slippage in order to prevent wind up. When a vehicle turns a corner, the outside wheels have further to travel and therefore need to travel at a different speed to the inside wheel. An open diff allows the wheels to do this. With a locked differential, both inside and outside wheels travel at the same speed, which on hard (non slip) surfaces can cause the wind up you're referring to.

Hi Doug, actually they go a long way toward protecting your transmission by preventing a lifted wheel from spinning, building up a high speed and then suddenly coming back into contact with the ground, which generates the kind of loads that can cause driveline failures.

Hi Tom, the green Prado had the factory LSD fitted.

Excellent demo! Just to add a little--Electronic ABS traction control systems are getting faster and faster as time marches on, and I've seen them work very smoothly, with a lot of torque sent to the non-spinning wheel. Not that I'm saying they'll ever be as good as a locking diff.

nice! i find the same thing with the tiguan, lock dif is so necessary, even a jeep in 2x with locking diff, goes a long way

Not an LSD at all just traction control that's it, it does not reflect viscous , torsen , clutch, or electronic LSD's

Informative - Thank you!

Ok thanks. I had ARB air lockers front and rear in a 94 Surf and there was pretty much nowhere it would not go. Im considering putting them in a 120 series Prado now and was just wondering if it would put too much strain on the Prado centre diff with everything locked up or if it is not even an issue.

Hi there, at this stage we offer a front Air Locker for all FJ Cruiser models. We also offer a rear Air Locker for models *without* the factory rear locker. If you have an FJ with a factory rear locker, and are looking for increased traction, then we'd recommend adding an Air Locker to the front axle.

Hi Bruce, if you give your local ARB store/stockist a call, they'll be able to explain this in detail.

That white prado also had a lift kit in it which gave it more of an advantage

well said .. where i live people are destroying the trails causing erousion 8( i like to four wheel leaving the ground as if i wasn't there, i got an 94' geo tracker (suzuki sidekick) do you make lockers for them? if so im getting them at our local arb dealer.

Hi Jay, check out the Air Locker Application Guide on our website for a full product listing (unfortunately we can't link to it here).

Can you use a arb locker for desert pre running? Or will it blow up?

@JimChap whats going to happen when tapping on it? Its a 4x4 car used for off roading...

Hey ARB, what would you lock first? Front, or the rear? And why? There are so many opinions out there, both with good supporting details but not enough to sway me either way. Thanks!

My questions are on a Toyota FJ Cruiser that has factory rear electronic locking differential and ATRAC system can ARB lockers be added? Would you recommend that the ARB lockers be added to just the front axle?

I drive a 2wd rodeo with lsd on most tracks people think they need all the goods on a 4x4 for. Good tyres and the right lines will get you most places. Years ago most people got good places in 2wd station wagons. Not having a go at real 4x4ers but it seems if you have the cash gor a brand new 4by and another $10-$20,000 for the ad ons, chances are you never actually needed them.

air lockers are a replacment diferential that uses a air operated piston to slide a spline inside the differential that locks the two axils together , it stops the wheel spin when one is in the air and alows the other to drive the car up the hill.

ARB, If I fitted Air lockers to a 120 series Prado, Do you still lock the centre diff when using the diff locks or leave it as usual, unlocked all wheel drive?

The wind up your talking about doesnt come from the diff, but the transfer case itself. its caused by the difference in power being place to the front and rear drive shafts, Eg rear wheels slipping will cause the rear drive shaft to spin more times than the front, causing the bind. A locker could help with that problem, but usually a transmision lock or Center diff Lock will force 50/50 power to both front and rear shafts stopping the bind. Toyota and Mitsubishi do provide factory diff locks!

i have question about FRONT ARB diff locker if i install this diff locker to patrol Y60 can i turn my stering wheel or not? or stering will be decresed to some % ?

If you had to instal only 1 diff lock on a truck which one would it be ? center or rear ? I still don't understand how come the Defender is such a good off-roader since it had only a center diff.

Looks like the white one has more flex in the suspension, major advantage. Very good vids however.

I had a good look at that too , but I think it has just been lifted ,if you look before the test starts it looks higher which could make it look as though it has better articulation but in actual fact its only some spacers ,just my opinion .

The first stock vehicle, the green one, which didn't have traction control had a rear LSD.

Hi 3XICS, we don't actually make Air Lockers for centre diffs as any vehicle that has a centre diff will have a factory locking mechanism.

Hi MrJdmposer, this question has been included in the FAQ section of our website. Check out the answer in detail here - arb.com.au/getting-started/ask-arb/

Did that first vehicle take a slightly different line or did it have a tighter suspension, because his rear tire came off the ground a lot higher than the last vehicle? That said, lockers are the way to go if you can afford them.

@fulsingh np .. but it basically boils down to the car companies preferring to use the bakes for traction control, since they have to add abs brakes anyways ... and then charge us for it.

@halloranedward And really, ABS is very useful, I would not want to buy a new car without them today. I can understand why they are compulsory. You could say that the market did decide that they wanted them very much. And I can also understand the company's desire to cut costs, especially for SUVs, where most of them will never even see a hint of the rough stuff in their entire lives. What we want, is better optional extras and the ability to shut the ABS off if needed. :)

just a tip about lsd's if you tap the brakes a bit this triggers the torque transfer.

Is this the toyota ATRAC system in the lsd rig?

@fathan16 ya i meant 2x4, got stuck in mud (stocktruck),,only one rear- one front pulling? 2x4,, put possi rear, then two rear one front 3x4,, put possi front, now all four pulling, true 4x4,, but noticed turning more difficult ,,,,, factory stickers should read 2x4 depending on traction 4x4 no AAA towing,

I preferr lsd. Too much potential for bunding in lockers. For the occasional off road trip, lsd is just fine.

@aodhanof90 Thanks man ! that was a great help ! I'm differently getting an air locker for my 4wd ! :)

@4x4trax putting your foot on the brake applies equal pressure to left and right wheel, it will do nothing also do some research on friction, static friction is stronger than kinetic friction so it would have the opposite affect you are hoping for

Two Questions here.. How The Air locker will act in a car have a TC ? and what is the effect of the Airlocker diffs in daily driving ?

Does anyone know if it is possible to place front and rear difflocks onto a vehicle that has traction control like the Toyota Prado Grande, the model shown in this vid?

What is open diffs?

@ossme there should be no problem with air lockers installed on a vehicle equipped with electronic TC... electronic TC works by sensing the speed difference between the two wheels when one slips, with the locker engaged there would be no differential in speed so TC would not come into play. When your lockers are not engaged the diff is open, so there is no difference between the stock diff & the ARB diff in daily driving. hope that helps :-)

Hi Mr Hayward, vehicle manufacturers cannot simply void your warranty because Air Lockers (or any other after market products) have been fitted. The latest consumer laws, which are now uniform Nationally go a long way to ensuring consumers are better protected in this regard. If correctly fitted and operated Air Lockers are proved to have caused damage to other drive train components, then we will of course stand by our product and rectify any such issue.

No, not at all. Many vehicle 4wd systems automatically engage the centre diff lock when low range is selected. If you give your local ARB store a call, they'll be happy to explain it all in greater detail.

They say you can use the brakes to lock up a LSD if a wheel is in the air. Is there a way to do this in a manual trans?

Not the steering range but the arm effort you need to exert to tun it. It makes it harder to turn. Rear lockers are fine on mildy dry roads, never use freont locker unless your front axle is slipping

Definitely had an LSD in it, Ballader. All 120 Prados that didn't come with traction control had a rear LSD. Some LSD's certainly work better than others though.

Hey look its mr squiggle!! Yeah $3k is a fair bit but its much better then any alternative :P That figure drops to around $2600 if you install yourself

You could have applied some break. That would have caused the power to transfer.

@johnvineyard67 you dont know what 4x4 means do you? the first number is how many wheels is on the vehicle. a 2x2, i think i saw that on an episode of pawn stars, it's a 2 wheel drive bike.

Hi 27TUBGUY, if we have a front Air Locker available for your vehicle, then yes, that's certainly an option.

I don't understand how the LSD is letting the rear power onto the 'air' wheel. Is the LSD based on a Torsen setup?

how can i take it?

Hi Rooster, relying on extra momentum and a heavier right foot may be an option in some circumstances but it also increases the risk of vehicle damage. Air Lockers enable you to drive the same sections of track with much less of a reliance on momentum which ultimately improves safety and prevents vehicle and track damage.

Suspension travel on the white prado was far superior to the travel on the green prado. Cheers

elegant..

Hm ja, that is why germans put into LSD cars (old 4 motion) electronic rear diff lock. And it works :-) I could not imagine, what would happen in my Isuzu with TOD (torque on demand). But at the end it simply climbs on such tracks (old english off road school - go as slow as possible and as fast as necessary)

All Toyota prado s I own a 90 series prado 3400L v6 vx grande and a 2021 prado gxl

The Difference between Electronic Control and Air lockers does not compute to a $3000 spend, from this video....

@ARB4x4Accessories

Hi there, this video was just to demonstrate that a 4 wheel drive can become stuck on even a tame looking section of track, when front and rear opposing wheels lose traction. As the terrain becomes more difficult, the gap between locked differentials and traction control becomes much greater, to the point where one will be the difference between making it through, and not.

why air? why not solenoid?

Wonder if that marker was permanent? Now you have just added a price of a respray to the hood, and the filler for the marker dents. Should be getting close to that $75k mark.

YEAH ok .it`s pretty much complicated i think . Above all i don`t realise the LSD mechanism,as i thought it has to stop the spinning wheel to the rear axle. It`s like open diff and i seek its function. My second thought is that the prevailing arb is really better than subordinate `traction control`, but the result is not far different as to make you swapp this system ,let alone ARB`s cost .thanks

$600 for my 4wd. Who cares what i spend on it, i'll still be ahead of these guys haha

why does differential windup happen,can locking the differential leads differential more prone to wind up ,should air lockers be used for a little time only ? could we use them for long time ? there must be some drawback of differential lock otherwise companies would have been providing it themselves!

yes but it still results in a legal battle and toyota have more money than me. i will eventually get arb lockers but not until the warranty runs out

Try turning a corner with that front locker on...A real good TC system as the D4 has will be as good as front and rear lockers at no extra cost.

IS THAT A PERMANENT MARKER?

@XxMudslingaXx Then have problems for the duration of owning the vehicle.

I'm a bit cross with the title of the video .. no LSD was tested here ... there was open diff, traction control and air lockers. @fulsingh The main drawback of lockers are added complexity and cost of manufacturing. Companies don't like that, so they try and use stability management systems to act as a sort of pseudo lockers, as demonstrated in the video. It's cheaper for them. Also, while lockers are engaged, you have bigger turning circle, tire wear, and decreased high speed stability.

no doubt they are the way to go but your warranty for the whole drive train is void. Yep engine gearbox transfere case and diffs. If something lets go (which is not uncommon) then you are stuck between the dealership and arb on whos goin to fix it. Ill wait till the warranty runs out then its off to get me lockers

A lot of electronic traction control systems vary, depends on the program behind it. Hummer H2 Electronic Traction Control used on the Holden Adventra actually preforms a lot better than the electronic traction control shown here on the Prado's. You'd be surprised how well a good electronic program designed for off road works CrossTrac a very underrated traction control system I've experience a great deal of results out of. Obviously nothing beats lockers but it has some real capability off road. An old but really good explanation of the system here from 2003 when they first released it kzread.info/dash/bejne/qp6T2Mh9fse5XcY.html

@casperman32 Agreed

@Steve H lock it

@johnvineyard67 I think you're confusing wheels that have traction, vs, wheels that have drive. A 4x2 is a car with 4 wheels where 2 wheels have drive - You ususally say FWD or RWD instead. A 4x4 is a car with 4 wheel where 4 wheels drive - If it has open diffs and two wheels spins and two wheels don't, it's still a 4 wheel drive car, it's just stuck. A 4x4x4 is a car with 4 wheels, where 4 wheels, with steering on 4 wheels - They are rare, and mostly custom made vehicles.

it seems to me a lot of the Aussie off road vids, the guys dont use low range much. i always use low on obstacles. 4 low and let it crawl over it. whatever you do to your rig/tires/diffs/etc what you are reaching for is better control over obstacles so you dont break axles.CV's or u joints. an ARB will give you a large portion of that control and help cut down on breakage. please do consider that facet when you calculate the ARB purchase and install costs. AND do be sure to purchase the air line repair kit and even a spare air line. great insurance for being in remote places with broken/inoperable parts.

@bradleycampbell5933

it seems the idea of the amount of control in driving is lost on a lot of european and australian off roaders. low range gives best control and reduces the work loads and strain to your vehicle. i suppose rockcrawling is for low range in their minds.

@Jesus45U oops sorry, i was in a big hurry ! was going to point out that it would be neat if we could to letting gearheads design trucks and let the market decide what is on them instead of them "having" to add abs. There is in infinite way of doing every function on a pickup or car, and having some bureaucrat who rides a segue legislate which systems to use has not been a big help to any one. any limit is always a maximum , not a minimum, for qualiy.

air lockers,, a true 4x4,, but,, try turning with the front locked ,, it will want to go straight,, I always wondered ,,,a factory (4x4) is realy a 2x2,, one front,, one rear,, its not a (4x4) till you got ALL wheels pulling no matter what,, nice vid,

@Douglas calderon, i am in no way paid to say this nore have i been asked too. i have a hilux with dual lockers, before i put them in i blew my rear diff twice and my front diff once, all from having to go up hills fast spinning tyres, since i had my lockers installed i have not blown a diff yet...... u be the judge

No, the LSD Prado has no traction control in this vid.

lol looks like fun

@halloranedward ... intersting reply ? :)

Spare us the bloody music in the future

@diegomayan not offroad you wont maybe if you had 1 tire on pavement and 1 tire on dirt and you punched it yes maybe but once a locker is locked it stays locked till you drive strait for a while the only way you brake them is making them lock up under extream stress rapidly like punching it once they are locked they are really strong and hard to break even turning wont brake them worst care u just drag a tire in a curve and chew up tires

How about arb lockers vs tru trac

i want to, but i live in Baku (Azerbaijan)

"you think that drive was to extreme for what you want to do" if your not going extreme you dont need lockers

No, certainly not :)

the grande has alot more than traction control over the gxl

Not really right having 2 vehicles standard and 1 modified. Next time show 3 vehicles with the same mods and 1 with lockers. I have a 96 GQ Patrol wagon with LSD no lockers and I keep up with the locker vehicles no dramas. It comes down to driving skill also not just the Mods.

Take driving skill out of the equation. Take two identical vehicles but one has lockers then run the same line at the same speed over the same obstacle with 2 diagonally opposite wheels in the air...lockers win every time! So it's not about driving skill. Lockers provide you with a mechanical advantage the other systems don't and it doesn't matter if your lockers are air activated or manually engaged. That's juts a convenience factor.

magpuld44 I don't disagree that driving skill matters on a trail however this video is not about DRIVERS getting across obstacles. Its a comparison between two pieces of mechanical equipment to see which is better at overcoming obstacles regardless of the drivers ability. An experienced driver can probably get a two wheel drive truck without lockers across the obstacles shown in the video but what would be the point in showing that?

oh no its permanent texta !!!! lol

Lol, did u even watch the video. It locks the diff making both wheels rotate at the same speed.

@mafiouso No they don't...... TC is shit, having used the both locking diffs and tc. lockers are way way way way better!
