Outer Limits 4x4 Board

just wondering what people think is the better locker now that the tjm ones have been out for a while. arb or tjm? cheers

Personally from when i asked the same question the response was about 70% ARB 30% TJM

The TJM Prolocker has come a long way and is engineered well nowadays i have heard.

I have ARB front and rear, i have no complaints.

This has been covered before

....

TJM lockers are scarse and might not be available for your vehicle.

Cris

thought the question might have been asked already. when i searched the forum nothing came up. cheers

after reading through the four pages of previous discussion on this topic there wasnt really any useful information there. maybe they ( tjm ) still havent been around long enough for people to break em or maybe they are good coz no one has??? dunno. guess i will get on the arb band wagon coz they are tried and true.

You could always try the Ebay chinese air lockers!!

That's a reasonable question, lockers are a big investment and if I was buying new I would want to research it too.

Hope you get some sensible answers, I have only ever owned second hand ARB units so unfortunately can't comment on the TJMs.

I know a few people who swear by auto lockers as well, having busted ARB units yet not busted autos in the same vehicles and under the same conditions, and they are a lot cheaper.

Cheers

For what it's worth:

From my idle browsing of such threads, I don't see that there's a strong case to be made for one over the other.

If I was looking for a locker and had the choice between the two, I think it would come down to price.

If there was no significant difference in price, I would probably go to whichever shop I felt more comfortable with - after-sales service is also important.

If it was still tied, I'd probably go the TJM - I have vague recollections that (on paper) the pro-locker offers some minor technical benefits. But I would double-check the pros & cons before I handed over cash.

Having said all that, I do like the specs of ARB's new compressor.

a 2nd hand arb is always gonna bust before a new auto locker.

an auto locker is always gonna become a mini spool (%100 locked) before a 2nd hand arb is gonna bust anyway.

might aswell just weld front and rears and unlock a hub when you wanna turn

Can you explain how you've come to this conclusion?

And which "auto locker" are you referring to?

i think he is just making a genarilsation that once worn, things are diffrent than if you have a brand spanker, so a new auto = better than worn manual locker, worn auto locker = worse than worn air, i think that was his point. but i think it would all be maintenace, and abuse

are tjm even making the prolocker still?


there are none available from stockists,always on back order.
they are only made for a limited number of vehicles.

arb have a huge application chart for 4x4's throughout the world,not just toyota and nissan.

with tjm moving all their manufacturing overseas,i would be very concerned about the parts availability in the near future.

it may not be well known,but tjm,as a company,are in big trouble financially.
they have made stuff all profit in the last few years and the decision to move manufacturing overseas was the only way they could keep going...for now.

as far as which locker is better?

how many of the 4x4's in competition use arb compared to tjm?

about 95% run arb lockers.

i wonder why?

no need to research,they are simply better.

is that plain enough for you?

No it's just a statement of your belief with no evidence to back it, pretty useless information for the OP and an easily formed opinion for anyone who reads mags and believes everything they read.

Hey mate there all just being bitches look it comes down to what u think i have a arb locker and been fine but i have heard that the tjm ones are justb as good. the are arb are a bit cheaper and the are well used but u have to start some where and the tjm could be the next best thing i know i haven't help much but go with your gut and get what u think is best

Why are they "simply better'?

wish i had shares in ARB..... all jokes aside why are they so much better??? have you used both? i am looking at auto LOKKA because im on a budget, but would love to hear your opinion ( ) all the same.....

I have been told that ARB have changed the design of their Locker and the comp boys are breaking the new ones regularly.
If this is true it makes the whole discussion “what’s better ARB or TJM” allot more relevant.

Ive been TOLD lots of things

I got told the world was flat

Here we go again.

Bazzle

if the ARB ones are cheaper go for them. Also if there is a waiting list for TJM then that would suggest that spare parts could be a problem.

I'm not a fan of bolt on ARB but lockers are one thing that have on my car that I don't mind, and acutally enjoy

A little bit of inside information. The prolocker was originally based on the US mcnamara locker, but isn't any more, they changed the design a bit, they also had issues not using o ring seals. ARB did have an issue with their seals and now use two double tapered seals giving 4 good seals.

I'd go an arb over a prolocker any day (and have in the front of my GU). I've seen both put together and installed.

Also, good luck getting a prolocker now, TJM don't appear to be bringing many in.

Installed correctly the arb locker, 35's etc will cause standard hubs to break well before the locker does, having said that, the arb locker is designed to be 4 times stronger in standard configuration. Larger tyres etc is going to reduce this strength. So think of your application first and foremost.

Same thing applies to Chinese lockers, and to add to THAT mix, they are made in a few DIFFERENT factories!!

Alot of things are going to effect a locker; just because 'some of the comp boys' are breaking them (even if its true!!) is irrelevant to the VAST MAJORITY of us. Most of us will only fire up the lockers once a month if we're lucky, and then there's driving style; some guys will bust an old design air locker in 5 mins 'cos they don't know what they're doing and an experienced comp driver could have a new design air locker for 20 years.

There are SO MANY variables. Look at the tracks you drive, some guys bust CV's, axles, C&P's while other drive the SAME TRACK and break nothing!!

The same applies to lockers.

They ARE a big investment for most of us and replacing them if/when they break is NOT something that we want to think about, but at some stage, if you want them, you just have to go out and buy them.

funny thing is most comp people 'crash lock' airlockers these days. if you read the owners manual it states that this is a BIG no-no. but people still do it and blame the locker for something it wasn't designed to do. i'm sure the other lockers have the same engagement guidelines.

The history leeson you are sprouting is wrong. MacNamara Diffs (othewise known as JacMac) Is a Victorian company in SE Melbourne. The design was bought off MacNamara diffs by TJM, and was originally sourced for them by MacNamara diffs.

This may have sinced changed (perhaps the reason for the delay/backordering of diffs) but I would not believe that the design would have changed, given that it is a proven design (30+yrs) and also used by the Australian Army in their Land Rovers.

The design has never used O rings as it has an actuator (standard pneumatic off the shelf item) external to the the hemisphere and mechanical locking linkage only in the pumpkin. (better design)

Not taking sides, but clarifying an obvious source of inaccurate information.

Murray im not sure where your inside info came from but your wrong on almost every statement you made here. Damkia is on the ball though.

And the Pro locker was being made totally here in Australia even after Jeff(Jacmac) stopped making them for TJM. The only reason TJM took on making them themselves was that Jeff could not keep up on the demand and did not have the time to expand the product line. The Pro Locker was then being manufactured by a company in Toowoomba that TJM also own. Not sure on what the current status of the Pro Locker is as i am no longer compeating and am not longer sponsored by TJM. I was sponsored by TJM durring the time they were releasing the Pro Locker onto the market.

I also wouldnt be to worried about TJM taking their product manufacturing overseas as ARB have been doing the same thing for a long time now. Im yet to see the quality of either of their products go down hill since this has happened.
