Anyone had any experience with this brand? They're now advertising a new model to suit the Toyota LSD. $499 with 3 year warranty. As shown in this months 4WD Action magazine.

Have you read this off their website? Lots of info:

Yes, I have read all the info on their site and it begs the question: If it is so simple and so much cheaper than say an ARB air operated system then why don't more people go down that road? Just looking for any feedback from satisfied (or otherwise) customers.

The LOKKA are always engaged and disengage when cornering. The exact opposite to an air operated diff lock.

The LOKKA is noisy (gears disengaging) around town when cornering. I have driven rally cars with this style of rear diff and they felt very 'taily' when backing off the accelerator.

For my money I would put an ARB diff lock in the front and save up for one to replace the LSD later on.

Have fun.

Interesting that you would consider doing the front first when I would have thought the rear should get some strength given the number that seem to be failing?

Hi I can not see how fitting a Lokka would give the diff any more strength . The number that seem to be failing is in my opinion a suspension problem, the rear shocks are not long enough. The 120 lifts rear wheels very easy ,then the wheel spins and destroys the diff when it come back to earth. The 90 series had the very same rear diff but had more downward travel ,kept the wheels on the ground and no bust diffs.
Fitting the Lokka would stop the opposite wheel spinning so would help not busting the diff.
I have used one in a V6 4runner ,made a big difference off road,and I never heard it once, the old old ones used to click as you go round a corner but not these. I have several friends with these in the front diffs in Patrols also have had no dramas with them

Fairly long thread running on 4x4Earth:

Looks like they are a knock off of the "Lock Right" which is the original US manufacturer of this design of locker. Even found some info via Google 4wd Systems being taken to court over the design. They must be half decent at heaps of street racers use them, if you google them you'll find all sorts of users, ie; CalaisTurbo.com.au and StreetCommodores.com.au.

Id also like to hear from anybody that uses these in a Prado or other constant AWD vehicle.
Sounds interesting and from what Ive read, an alternative to an air locker maybe.

I dont travel remote so if the rear was to go it would not be the end of the world. Having the front fitted would also let you go slower than standard due to more traction so the chances of damaging the rear may also be reduced.

I fitted one of these to the rear about 3 months ago. Yes, if I put the window down and turn the radio off and tell everyone to stop the chatter I can hear it clicking as it disengages around a corner. However, that does not happen often and there is an imperceptible little click in the cabin around town, something I have gotten used to. Outside the vehicle on the tracks others can hear it though!

Offroad it is as good as a air diff lock without the worry of "have I turned it off". I can now approach steep rocky steps with gentler throttle, not worry too much about momentum and therefore minimal risk to the vehicle. Combined with the stock traction control it has really made difficult steep and rutted stuff pretty straightforward - now though I need sill protectors because I am able to tackle terrain that is more difficult than before.

When I fitted this there was not one available for, or recommended for the front. In a constant 4WD the effect on the steering is too dramatic. Bear in mind that the auto box acts like a shock absorber for the rear lokka and reduces drive train backlash so this does not seem to be a problem either. I am happy with it and I felt it was a good investment for the sort of driving I do.

Hi Dock, If you clear out your PM box I will send you a PM letting you know when yours will be available (soon if you want them)

I like the idea of not having the extra hassle of the compressor and where to put it.

If you are driving in terrain that needs a locker, then you should also be lowering tyre pressures, so you need the compressor to reinflate anyway.

Certainly can see the advantage in an auto locker though. The only disadvantage I see (assuming they are stong and reliable) is that you don't get the opportunity to drive with an open diff, which means that you may become overly reliant on the locker and not really learn to drive the best lines, once you can't go any further you have nothing left up your sleeve.

I always have a portable 75L/m tyre compressor anyway.

A Lokka just appeals to me as its "automatic" so to speak and without the need for a compressor, air lines etc, its one less thing to go wrong.
