Oh, and by the way, I bought from 4wdsystems your Lokka diff locks for the front of my Hilux some two years ago and they have made a world of difference to the offroad performance of my vehicle. I now have no fear of tackling any 4wd obstacle, knowing I can easily get through (well, more often than not). The downside is I spend most of my time towing my mates out of trouble who cant get through!

A belated thanks, barrier fitted perfectly!!

Well the diff lock is fitted (by ACT diff doctor) and took it for a run in July. As you would expect it changes the off road performance of the Navara dramatically. So much so that my brother suggested he would look into getting one for his Hilux. Anyway very happy with the increase in off road ability given it's a torsion bar/leaf spring setup, lifts wheels everywhere however the diff lock in the front axle makes the world of diference.

Just want to thank you for the recent upgrade with the front Lokka and part time kit for my 2006 GXL 100 series Auto Turbo Landcruiser.

As with the 80 series which I had for 12 years and 600,000 kms I am pleased with the performance, fuel economy and reliability from the Lokka and part time kit.

With my work in the Petroleum Exploration, Heritage Surveys, and Pipeline Survey industries, often in very remote regions of SA, NT and QLD; I need to access all types of terrain mostly before any road construction. I travel a variety of conditions, many highway miles, outback tracks and off-road scouting (often where no tracks exist).

Vehicle reliability and capability are paramount, as I often travel single vehicle.

I realised the reduction in fuel consumption ( 15%) and expensive wear & tear in the front end with the 80 Series and can report the 100 series is giving me similar results.

I had the Lokka fitted to make off-road scouting possible in the remote locations I work. I am amazed at the change in the vehicles capability with the front Lokka installed. During off-road scouting I have been able to climb sand hills that other standard vehicles -100 Series, 70 Series troopie & ute – were unable to follow, even in my tracks.

I have no problems with engagement and steering. I only realise I have it engaged when I occasionally hear the Lokka unlocking.I am extremely happy with the decision to install both parts, having achieved my original aims and much more.

I replaced my 80 Series at 600,000kms, having travelled 420,000kms with the Lokka and Part Time Kits fitted for the last 8 years.

Now with a 2006 100 Series turbo diesel auto, I have fitted the Part Time Conversion and front Lokka, with the same result. Off road performance is astounding, even though it has torsion bar front suspension. I was dubious about its ability prior to in-field use, but I need not have worried.

I would like to reiterate how happy I am with the Lokka and Part Time Kits, both perform exactly as explained and extensive use has proved them to be extremely reliable.

The more I've read about the Lokka (apart from what I suspected was BS on the Outer-limits forum), the more I'm convinced they're a much better product than what else is available & much better value.
I hope you don't mind if I post the feedback pdf on the forum to counter the misleading info, which was probably from someone who spend a lot more money on ARB lockers! However, there's a couple of reasons I will purchase a Lokka as soon as I can afford one;
They're automatic & reasonably quiet in operation,
The ability to steer while they're working, as it doesn't seem to me much use to be able to climb up some rocks, only to find that your vehicle drives off the edge because the diff-lock you've fitted won't let you turn! Cheers

I have the 137 litre tank and very happy with it. Did have to remove muffler and replace with a resonator ( 3 inch system) but happier with it like that. The tank served me well as it made up the cape and back with no hassles ( ie cracks or clearance) …...... The guys from 4wd systems are extremely helpful and bent over backwards to get me the tank in time. Also have the Lokka from them and I can't stop raving about it. You won't be disappointed.

Honestly Tom - I really don't even know its there and there has been no change in driving characteristics from stock even when first put in.

Congratulations on the work done to the Nissan, PR is not so focused on getting a new cruiser! Bloody ripper, we took a new cruiser for a spin while he was over here the other day, very nice,

Let me thank you for the replacement fuel tank and custom cargo barrier. Both installed perfectly on the weekend. After some of the horror stories mates had told me about fitting replacement tanks, I was a little concerned, but after seeing how you tank mounted I don’t know what I was worried about. Everything lined up perfectly and it was obvious that the design meant that even if thinks were a little off centre there was enough adjustment possible to take it into account. The cargo barrier fits perfectly, it looks better than any of the other custom barriers that I have seen. Thank you for supplying such high quality accessories. I will definitely be spreading the word up here about your products.
