automatic lockers

Here cost is about 600 US $, about 200 USD for installation.
I thought that it should be cheaper at your region), about 300$ per unit.

$590 FOR LOKKA - $400 fitting/machining and forgot to add I put on Manual Hubs $250 instead of the auto hubs so I could give the diff and CVs a break. Cheers tony

Currently I have LSD, it helps me driving, but to save tiers. On father’s TLC 80 I used 100% rear locker just after leaving asphalt roads… As for front axle automatic diffs is cheaper and you don`t neet to engage it before obstacle. But thanks for comment as well )

I had front Air Lockers on my Cruiser and now front Lokkas on my Rodeo. I see no real difference, they both do what they have to. Only thing is you have a compressor with one! I like the fact it is there all the time and steering is no where near as bad as some make it out to be. As for life of product - that is yet to be determined but I have given it some serious workouts and all good so far.

With a good LSD on the rear, I also would not bother with a diff lock in the rear. Cheers TONY

Agree with troopyman. Use detroit trutrac in rear diff, works all the time so even on asphalt roads then if you lose traction it will lock, you should not do this with an airlocker. And the detroits are better than any LSD ever made.

Fit ARB airlocker in front and you only need it locked when necessary and your not fighting it (steering) when it's not required.

The lokka's from memory have to unlock to steer.

You still need to engage a rear diff lock before obstacle as well.

My thinking is that with a detroit in the rear you have 2 wheels gripping in 2wd . Engage 4wd and you have 3 wheels gripping . Engage the front air locker and you have 4 wheels gripping .

Pretty much sums it up.

Although detroit trutracs are auto lockers as opposed to lokka's which are auto un-lockers and by rights are called helical lsd's. But unlike friction plate lsd's when they lock they lock 100%.

ie the trutracs will lock when slip starts, they are also better when towing as if the trailer is big (>2000kg) and it starts to push the vehicle the trutrac will still lock up.

Ian. Not sure why you said "remember' these units are auto-UNlockers" What do you mean here? This is from the Lokka Site -- 4. It should be understood that only when there is an external force being applied to a wheel to make it turn faster than the rest of the drive train will LOKKA allow one wheel to differentiate. Slippery surfaces where one wheel would normally break traction in an open diff cause LOKKA to stay locked - even with one or both wheels in the air LOKKA will remain locked.

Cheers tony

Lokka's are locked all the time and only unlock when necesary, like going round a corner.

Cheers

Yes Rossco, that is correct. When turning a corner the outside wheel goes fasted than inside wheel and therefore unlocks the Lokka but if a wheel looses contact or adhesion with the ground it continues to turn at the same speed as the wheel that is still on the ground.
System works well, totally reliable and inexpensive but as I said if you need to belt the thing around the bush then get an Air locker or Detroit locker.

The Lokka in the front off my TLC 60 was relatively cheap, very effective and has given no problems at all. The "steering effect" is there but not really a problem at all. Also, it only occurs when you are in 4wd. Rest of time, ie, when on bitumen, it drives as normal. they are at their best in sand dunes when you often want them, but want to be able to steer as well and don't want to be fiddling around turning things on and off. For long straight slippery stuff like boat ramps, compressor type could be better.
