4 x 4 systems lokkas

I had one in my 80 and loved , I did shear the pins in it once . had to come home 2000 with diff locked lol

They have a lot of info on their website ...

www.4wdsystems.com.au/html/lokka.htm - like most company websites you need to read past the hyperbole a little, but better info than most.

But fitting to a constant 4WD requires conversion to a part-time 4WD and adding the extra cost ... so I'm not doing Lokkas for my 100 series.

I've driven part time 4WDs with Lokkas (both one axle and two axle setups) and they work as advertised. Perhaps the two axle setup is a little more tetchy in the steering department off road but on road seemed fine.

i've got one in the front of my triton and i reckon it's excellent. it helped heaps going up the cape last year but the steering while in 4wd is abit heavier. the missus doesn't like driving it in 4wd drive now but who cares. the steering was the only thing that took abit of getting used but it's fine now. i don't have any dramas on road because it's not full time 4wd but off road they make wheeling so much easier. we had plenty of wheel lifting on the trip and it pulled us through every time

thanks all, was reading the archives on the subject (sorry should have done that at the start !!!!) so now i am totally confused!
cheers

Stick with air lockers, and there is no confusion...

It really has me amused why some people go and buy the cheaper products and still expext it perform 100% , as far as I am concerned there is only 2 options , as Truckster has just said, Air operated ,[with advantages and Dis-advanteges] or the Detroit Lockers [with advantages and Dis-advanteges] for part time 4x4 , use Detroit No-Spin fully Auto Locker both ends, for full timers use Truetrac. they employ special helical gears to transfer torque instead of clutch packs. They have the same on road action as a standard diff, control wheelspin, and are ideal for the front diffs of Constant 4WD vehicles. and you put the full No-Spin in the rear ,

Geoff,

I'll try and answer your question for you; however, I don't have a 4 x 4 systems lokka to my front diff, I only have a Lockrite fitted in the rear diff of my 80 Series Cruisers.

As far as I am aware the 4 x 4 systems lokkas and the Lockrite are very similar in design and work in the same way.

They are an automated diff lock which means they are active all of the time - that is in the locked state, unless they are required to release - such as when you turn the corner or go around a round-about. Sometime due to your speed or the size of the turn you can feel the locker re-engaging - and I do mean feel sometimes with a thump and the first couplee of times it happens it will make you jump.

Because they are permently locked the reccommendation if you are fitting them to the front diff on a constant 4WD - i.e Cruiser (not the standard but the GXL and above) then you need to fit a part time kit, otherwise the steering will be affected and in particular your turning circle and it will feel heavier due to the diffs being locked. So there is the added cost of fitting a part-time kit for your hubs.

On a Part-time activated 4WD this doesn't occur until the hubs are locked.

So you have to decide is there a benefit - of course they will improve your off road ability but at cost to your steering, so therefore you will have to learn to adjust your driving style.

With air lockers the same will happen anyway once you activate them - that is your steering is affected because the diffs are locked.

One advantage of automatic lockers is that you don't have to worry about forgeting to activate them when you need them - especially if you need them right away.

The other advantage is cost - air lockers are more expensive than auto lockers.

Ulitmately it is up to you what you want but first you need to ask yourself if you really need a locker of the front diff and would you use it enough to warrant the costs.

Hope this helps.

Hi Geoff

Firstly I have air lockers, front and rear. The front made the biggest change. I have driven 4wdrives with lokkas but I have draged lots more back to the road, I am in a club that does mostly touring stuff with the odd harder trip, they break CV's I pulled out 4 in 6 months, no one uses them in our club anymore.
As far as having to turn buttons on and off and this being hard, no it is not! I think some people are looking for problems that do not exsist.

Have fun

Geoff, I put one in my old 75 series front end. The steering was slightly heavier when in 4x4 on hard dirt but nothing to be a worry. Never had an issue with it.

The BIGGEST tip if you install one is make sure its installed correctly and preferably by someone that has done one before and you trust. There is a set tollerance that must be achieved - if its not then the system won't work as designed which I personnally believe leads to alot of the "negatives" that people write up here about the Lokka. The instructions give you some simple tests to undertake to check that its operating correctly. If your getting it done in a workshop by someone, do the test in the shop before leaving. Could save you grief down the track.
