G,day just new to the site and a real computer novice.
Wondering if anyone has had anything to do with LOKKA LOCK RIGHT DIFF LOCKS
Sold by 4wdsystems in SA. I have a 93 4.2 td 80 series gxl so is full time 4WD.
With these lockers you convert them to part time 4WD with some mods.
If there is anyone out there who has used them i would be interested to hear what you think before handing over the hard earned.

thanks

I have them on my 96 80 Series but mine is STD model so no full time conversion required. I went witht hem as I thought that they would be a good alternative to spending 3 grand on air lockers and so far they haven't let me down once. Not sure whether or not I'd do the full conversion though, that would depend on cost.
With TD and Centre diff lock I'd imagine you'd get to go most places anyways.
Bottom line - I'm more than happy with what they've done for my machine and I have actually made it up inclines that others couldn't despite being underpowered.
If you've got the bucks I'd probably put Air Locker on front but again there's nothing wrong with the Lokka option. Others might tell you different.
Feel free to contact me again if you want more info

I've had a Lock Right in the rear of my 4Runner for 100,000kms (3yrs).
The differance between a non working LSD and a Lockka is, as you could imagine, was brilliant especially crossing deep washouts diagonally when one wheel is off the ground.
For the price of one air locker you can buy 2 Lock Rights at least, twist Tom's arm and you could get two for $850.

G'day Rox
Check September's issue of 4wd Monthly magazine on pages 102 &103 for Gear to Goannawhere add.
80 series front & rear Lokka's $646.00 each.
Twist their arm and do some haggling.
When I bought mine I was offered the second one for $200.
I only got one for the rear.

Safe travels

I dont like them. they are ok if you want to run on dirt all the time like around a farm or a comp car, but for duel purpose, not as good as the air locker.
Your front diff is weak as it is, the air locker strengtherns it up by holding the ring gear more solidly, the auto locker puts more strain on the original hemispheres' weak spots from more traction. When you accelerate in 4wd, your steering wheel becomes a weight machine....i hit a tree this way with one in the front.
With one in the rear, i had axle studs snap off from its action. All the forces put on the drive train and steering from the diff locking due to acceleration or load, can only be negitive.
With the air lockers, i can decide if i need or want the above mentioned action.
No tyre squirming, no big bangs from the diff around corners, my opinion, keep it constant 4wd, and put one in the rear if you must. They are only $550 for the slippery conversion, but be prepared to wear tyres and possibly break axle studs.

CV joints would be the weak spot by my reckoning.
I've busted them in my 80 but not a front diff

Going forward, the c/v is weakest, going back, the diff crown and pinion....check out the archives on broken 80/105 series front diffs....

I run one in the back of my 80 series and love it , it works well and I really have to concentrate to hear it clicking on the road . Forget about one in the front , I have been down that road and it isnt worth the head ache , for starters , you want the option of turning it off to go around trees in the bush and this just wont happen in a locked up car . I wasnt willing to convert mine to a non constant 4by to save minimal in tyre wear . For the front make sure its a air locker . I like the idea of some sort of lsd in the rear were i had nothing before .

I might add , forget this cr*p about you can do it your self in the driveway . There is no way it can be done at home , even if your a mechanic . I am a mechanic by trade and needed to take the center to a diff place to get shims to create the specs they ask for . I dont like the way they ask you to remove the crown wheel with the tabs not to loose your preload , its realy easy to damdge a thread . Spend the bucks and have it done at a diff place . It all depends on the ware of your diff as to what shims you need to get it centered and spaced correctly

Hi Marty,

I had the lok right in the front diff of my 80 series (part time 4WD) for well over 100,000kms. The difference it made was unbelievable. As for it pulling the steering, it is noticeable as you apply power, but only until it "unlocks", then there is no effect.

Its main advantage over an airlocker is that you can still steer on say rocky hillclimbs where there is still some good traction. An airlocker will drive both front wheels regardless (you loose steering control and have to turn it off), but the lok right will allow steering action. The best way I can describe the effort on the wheel is that its like loosing the power steering for a brief moment (while it unlocks). Once you have had it for a while, you don't even notice it, but each to their own.

However, I would not convert a fulltime 4WD to a parttime 4WD. I would either fit it to the rear (2nd choice) or go a front air-locker IMHO for this application.

Cheers

Captain

I rang Tom @ 4wd systems today, 80 series std part time $595 front $545 Rear. $12 postage each. But people say haggle!!

It apeares to me that if you have a part time 4wd the both lokkas are good cause you turn off the front end with the free wheeling hubs on the black stuff.
But if you have full time 4wd you will get tyre were and harder stering when accelerating. I have a non turbo diesel so its prety gutless + part time 4wd so i will pbobly look in to this as I can get both for same price as air lokers.
Thanks all for you replies , experance & opinions.
