seriuosly after studying the cad drawings for pro locker and airlocker the prolocker argument is funny, no seriously guys if you believe the prolock is stronger than keep the jokes comming! on second thoughts you better stop, i may pee myself.

oh, and tjm really have no idea how to market things, the web page for the locker is pretty vague.

the other thing to consider is that the pro locker is only available for limited number of vehicles so you may find it isn't even available for your vehicle which you neglected to mention what it is

What is so strange/weak about the design??? IMHO it is as strong or stronger than the ARB. Both have been tried and tested over many years and found to work well - the Prolocker is designed by Jacmac, and now licenced to TJM for some vehicles.

The one big advantage of this design, is there is no moving o-ring to leak air into the axle.

the air system is the main reason I like the pro lockers.

I dont work for TJM and have no affiliation with anyone workin there, so I have nothing to gain from any sales.

The ARB guys are quick to bag the pro locker with out anything constructive to say.

mmhey if you can see a problem with the pro lockers point it out. I have not encounted a pro locker with a sheared of bearing spigot yet, I have had real would experience with ARB's doin this though.

As I have mentioned ARB are strong enough for the joe blow and most comp guys have no problems, but some do have issues and the bloke askin the questions is buildin a winch challange truck where you would not want a DNF caused from a leaking O-ring.

well, i do believe when the pro locker came out all thier selling points were just baggin the air locker.
jac mac's biggest selling point was they used vacuum, so when tjm go to compressed air why is it better? they still have a seal seperating the oil from air.
which o ring are you talking about? the o ring that engages the clutch is just moved by air. the operating ring of the pro locker uses steel on steel.
pro locker does have an o ring to leak air, not saying it will, but it does. air locker keeps metal to metal contact to a minimum.
when you talk about airlockers failing you have to take into account many things.
unless you are a diff expert, don't install them.
most problems are caused by self fits.
when bearing journals are sheared off this is usually caused by fitting error, everyone thinks they are a diff expert!
when pro locker has sold the same amount as airlocker around the world then it is ONLY then we can do a reliabilaty comparison.
why do tjm copy the arb wiring loom exactly?
why do tjm copy the compressor bracket exactly?
when you work with diffs everyday you see what is good and what is not.
it's a shame we don't get alot of jap slippery's here in australia, the aftermarket there is awesome.
and like i said, when the prolocker came, thier selling points were mearly bagging the airlocker.
when you see thier engaging mechanism, it's very agricultural.
my 2 cents.

i was just told that the pin/rod thing was made of hardened steel and just wasnt up to the grade for bigger tyres and higher HP

a bigger diff, and a locker to suit that bigger diff should be considered. usually people try go for high horespower, shit gearing, and stock diffs, won't work.

Welcome to the pissing contest.


the air locker have 2 viton O-rings that run on one of the bearing spigots, this is where the air is transfered into the carrier to activate the locking mechanism.

An O-ring is not designed to be a radial seal where a shaft turns inside it, this is why I prefer the prolocker.

If you also look at the components that are used to make up the cross shaft assembly on the ARB there are at least 5 parts to TJM's 1.

Yes the locking pins an the pro locker are agricultural but it works, just like the factory nissan dog clutch.

I dont care about how each company markets the products, I was not marketing either of them.

How would you do the wiring loom? The ARB loom is very basic and it doesnt leave much room for variation, but they are not the same as the pro locker switches use a different pin configeration, but who gives a shit.

mmhey would I be correct in assuming you work for ARB? yes I prefer the ARB locking mechanism it has much more contact area but this in not where the problems are.

All the airlockers I have had to repair have been installed by ARB stores, I cannot comment on how good there techs are.

I never claimed to be a diff expert.

than whats the difference between axle seals, they have a shaft turning inside them? the main piston ring which engages the cluctch does'nt turn on the piston, it just pushes it. and those 5 parts are made to more tighter tollerences than 1 complete shaft. and you not being a diff expert is my point. oh and manufacture sheet metal components. this ok?

it has nothing to do with axle seals, you need to go look at your exploded veiw again, but waite it does not show the 2 O-rings on there.

The only sheet metal I have ever worked with has been shim, I have manufactured diff locks for another company that makes selectable lockers and now work for 1 of the world leaders in mining equipment and no its not CMI, but that is beside the point.

So where is your information on the ARB's good points or superior features aside from sale numbers?

I have not made any personal remarks toward you or about your profession, which from your comments must not be very professional.

Either you are someone who also has another user name (as you joined 2 days ago), or you work for ARB and have only logged in to defend there product that has not been attacked.

I own both products and aside from the O-ring I am happy with my airlockers. I also own alot of other ARB products (aside from the pro locker I dont know if I have many other TJM products?)

Axle seals (lip seals) are clamped in position by the outer, O-rings in this application can spin and wear.

So what do you do for a crust them mmhey? Its obvious you have a dislike for fabricators.

Cheers Mick.

I had my pro locker in my 80 series replaced under warranty no Q's ask though

theres a thread about it here

http://www.outerlimits4x4.com/phpBB2/ft ... hlight=pro

jimbo

the first prolockers had a pooly designed mounting braket, this has been fixed apparently.

One of the pro lockers had a similar problem where it would not disengage. The bloke that installed the centre bent the actuator bracket, so would not disengage and blew a CV.

He straightend the bracket and has won some comps and still competes in winch challenge events with the same locker.

I never said there have been no pro lockers fail, just I havent had to fix one, but have had to fix ARB's.

Hows the pro locker now jimbo? would you swap it at your cost for a ARB like the thread question?

owned detroit, lockright [ woops, still have one]- don't get me started on those items!
and by being a HUGE fan of boeing aircraft i work for boeing? [ could do, they have a factory in melb!]
or by being a fan of vic rail and building custom n scale rollingstock i work for national rail?
love toyota corolla's, maybe i work for toyota?
or an expert on flight sim i work for pmdg or justflight?
its up to people to decide what they want, but usually there are so many variables that the truth gets very lost. i would say don't waste your time on detroits, but heaps of people go for them, thats thier choice, but when opinions are based on loose fact its a problem. if i want plumbing i go to a plumber, got something wrong i go to a doctor. i'm sure this will continue.

The only sheet metal I have ever worked with has been shim, I have manufactured diff locks for another company that makes selectable lockers and now work for 1 of the world leaders in mining equipment and no its not CMI, but that is beside the point.

Do you know what selectable means, I never made reference to an auto locker, so you obviously dont know your stuff and anyone who would choose an LSD over a locker for comp work is a pill.

So who is owned? You still have not bought any argument for the ARB only prooved you can not read, but I have found this amusing .

you learn a thing or two when you have owned and or repaired every kind of locking or slipping diff.please, go out and buy what you like, the money aint commin to me unfortunately oh, and my wife owns me! i can see why people in the industry don't come forward too often, get thier arse chewed off! glad this doesn't happen in my bizz. [ and if anyone noticed i did say what i do in my last post.]

AFAIK Jacmac used to offer either vacuum or compressed air, however these days only make compressed air lockers. So TJM haven't been doing anything different to JM.

WTF is wrong with an agricultural design??? The average 4x4 tractor would walk (drive?) all over a 4x4 offroad!!! My current locker is a Maxi-Drive, which I'm sure you would class as even more agricultural, but the design has been tried and tested for years and is extremely reliable.

Enough spinning drivel - They are both good products, and personally I would base my decision on price - if the same or close I would get a Prolocker though.

no never I now have twin pro lockers in my 105 series and the arb one wont warrant there locker if you run bigger than 33's were as tjm dose

jimbo

Just been to the show last weekend and tried to get a quote on the Prolocker from TJM and was told that there not getting them for a couple of months until they are able to completely make them in house as there have trouble with getting them from macnamara etc!!! Hence I now have an ARB locker fitted thanks to Ron aka RVH96.

just like your initial post? ARB have sold over 1 million lockers world wide over many years for many types of vehicles, hardly due to an unreliable design. Not sure what you mean by proactive to peoples questions?

Probably that you are quick to jump in with comments on any thread that mentions ARB

nope I jump in because people make rash genralistaions without adding the detail that nasty troll did afterwards. It just happens to be on a lot of posts that involve ARB, purely coincidental
