Outer Limits 4x4 Board

Have searched, didn't find anything. Looking for any information on the performance of TJM's pro-locker.... reviews etc.

checked them out today at the 4wd show ,kim bolton runs them on his comp truck and they have less moving parts than an arb locker and no o-ring. About the same price as arb's proven air locker.

I'm running them on my patrol front and rear running 42s and have given them a couple of good workouts and they have worked well.

There new comprssor setup is heaps better then ARBs to in my opinion.



Cheers Mick.

There was a big ARB vs TJM thread a while ago, but i think it turned into a shit slinging match and got quarentined.

Layto....

I saw it at the show as well.

I liked the compressor setup.
Didn't like the amount of sound the locker put out when locking but that doesn't mean much.

Overall - I want to encourage competition to ARB so would go the pro-locker - after I get around to my axle swap anyway.

amount of sound?

like compressed air sound?

They retail for a bit more than the ARB but ARB have just put their prices up so they are closer in price now. You can still get an airlocker a bit cheaper but there are no o-rings in the prolocker so it comes down to personal preference.

Whats wrong/right with the O/rings?

Cheers

The o ring wear out and leak air into the diff housing, sending oil up through the air hose, making a mess in the engine bay or where the compressor is.
To change the $2 o ring you must remove the diff centre. PIA

Cheers Matt

the orings also wear out the collor where they run meaning that the center has to come out to machine it up to make the orings seal again. how ever i think a little cunning with a speedie sleeve would cure it too. also the orings are 5 bucks each i changed a set last friday

I have a Prolocker and couldn't be happier. I have locked in it under heavy load and while moving whitout a hitch. The compressor is excellent and can pump 4 big tyres up with ease

i think his talking about the puff of air when the solenoid opens. With the TJM compressor you can pump up your tyres with out it s*&ting it self.

I think the TJM Locker will also Unlock when it is under load.

Mick is this the case?

Yes it has does but I guess if you load it up enough it may not but time will tell i guess.

Cheers Mick.

to set the record straight (again), the ARB air locker o-rings do no wear out any faster than the rest of the diff (I have built air locker diffs that now have over 200,000km and still going on original o-rings), nor do they cause wear on the bearing spigot extension, although wear can occur in that spot if the oil becomes contaminated with mud/dirt/wear debris from other parts of the diff. Almost all air locker problems occur at installation time.

This is not to say the TJM product is no good, I'm sure it's great, but only time wiill tell if it is as cost effective, reliable, serviceable/repairable and bullet proof as the ARB product. I hope so - some true competition might drive the prices down a bit.

a quick search will reveal a lot of air locker tech dealing with the leaks and the oil 'problem'.

cheers

well if they dont differ to much in performance, i just became a fitter at tjm in perth ocoonor so i might have to chuck some on the 4runner

how much r they retail

Keep in mind this is not a "NEW" product its just been bought out by a larger company. This product has allready proven itself over years of reliable service by the rover community mainly. Ask any Rover owner that has had experiance with the 2 which he would choose first if he were purchasing again and im sure you will mostly get the same answer of the TJM(AKA-McNamara). As far as i'm aware it has been around just as long as the ARB Airlocker(AKA-Roberts Locker). If anything this will now become an even more reliable/repairable/servicable and Bullet Proof product as TJM is now building and controling build quality and supplying after purchase support.

But i doubt the competition will drive down prices. If anything there going to rise. (I think ARB just had another price rise didnt they?)

I broke my Pro Locker in my 80 and tjm sent it back up to HQ in brissy
and they fixed it under waranty they said I was the first one to brake the locker anyway heres a bit of info for you TJM will warrant there locker no matter what size tyre you run where as ARB only warrant up to 33" tyre's so even though I broke my pro locker when it come's time to buy a locker for the hungy it will be a pro locker again.

If your after a review of no difflock/ETC/ARB/TJM/Detroit difflocks

Get the newest 4wd monthly mags has 2 other mags with it one has a big review of the same 4wd with all of the above in them, would seem they rated the ARB the best and the TJM second, and the Detroit last, but all very good and worth the money either way.

Take a read of that, goes for a 4-5 pages as well.

I hate the mags, paragrph review of a product. waste of time even writing the thing.

Of coarse they would ARB pay the most dollars.

You only have to look at the ARB ads in 4wd monthly to know they wont bag anything they sell.

Cheers Mick.

I hope you don't believe everything you read - [I'm sure you don't Zagan....]

Cheers

Although i generally agree that 4wdmonthly, and all mags, are biased towards their key advertisers' products, it'll be interesting for you to know that an ARB snatch strap failed prematurely during one of their testing comparo's a couple of years back and they did not suppress it from publication.

Sometimes the advertisers' product IS the best product

I'm not going to agrue with you.

We are a little off topic here as it is but they would be stupid to hide a fault of a product that they tested if it could save someones life. They wheren't up ARB ass as much then as they are now either.

Cheers Mick.

I just wasted another $9.95 by buying 4wdmonthly only to realise the article you refer to is from a very old publication and has no reference to TJM Prolocker whatsoever as it wasn't released back then. What it does compare is ARB airlocker, TJM Lockright auto locker, Detroit auto locker, ETC auto locker, MaxiDrve vacuum operated locker to an open diff arrangement.

I would say from this list that the ARB airlocker is a clear winner. The mag actually states "When all is said and done, it's definately a 'horses for courses' decision!"

Hopefully they do an unbiased up to date comparo soon as i'm in the market for a rear locker at the end of the year.

So where did the Maxi-Drive come in?

[/quote]So where did the Maxi-Drive come in?[/quote]

as far as that mags concerned its just rover junk

This is my adlib version of article.

ARB and Maxi Drive: distinct advantage of being selectable by operator/driver. One is air activated, one is vacuum operated. Both will result in an open diff when off.

Detroit and Lockright: cheaper than above. auto lockers, so will automatically lock when needed. Disadvantage is may require some heavy footing to make em needed, and are always on/off even on road. Can wear out quicker as they are in constant use.

ETC: similar to above as in an auto locker, no input required. This system applies brakes to spinning wheel(s) thereby directing drive to other wheel(s). Disadvantage is that it engages after wheelspin has already occured, which in some cases may be too late. Often requires a bit of heavy footing to make it slip, therefore work. Fitted to Rovers and would be too expensive to retrofit to other vehicles.

It does not rate in order but allows you to decide on what best suits your applications/budget.

theres one here for sale

http://www.outerlimits4x4.com/viewtopic.php?t=105400

is that a good price what do they retail for?

If that comes with the compressor then it's a cheap.

The lockers without the compressor retails for about $1200 or there abouts. The TJM lockers can run off the little ARB compressors or you can run the TJM comprssor which is an Ox compressor and set up like the picture of mine up the top.

Hope this helps.

Cheers Mick.
