As oompie said before .. for diff lockers on Nissan .. speak to Mike Swann . 082 569 4183.
He was the FIRST in SA to to put lockers on a Nissan Sani [fron & rear] His prices ar half that of ARB. He gives personal attention. And he stands buy and quality control the installation. And their guarantee is a "no backtalk .. just replace attitude" .. I like that

Dusting the cob webs off this post to get some updates from people who have had front lockers installed and thier experiences with them.

I am particularly interested in the autolockers. How do they work? I have heard two extremes of operation. One is that they only lock when you need them and the other is that you find yourself not being able to turn on a tight obstacle bacause the locker is locked?

Anyone have support for the e-lockers? It is my favourite option at the moment.

Autolockers available for a patrol front h233b diff: LOKKA, Lockright, Detroit (more pricey than the other two).
Also Spartan - I dont really know this brand.

The autolocker only locks when there is power on the front wheels. (must be in 4h or 4l).
It disengage when vehicle turns, then inside wheel will lock. "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. ".

As mentioned earlier in this thread: speak to Ronald at 4x4traction or Mike Swann. They both very knowledgeable on autolockers..
I know Ronald has been driving with autolockers in his 4x4's for many years and swears by them.

Consider me more enlightened :oldtimer:

So watched a bunch of videos and did some more research and I must say the torson style limited slips appeal to my love of simple engineering principles. But the lack of full lock turned me off them.
The ARB airlocker is just something I am not into... too complicated even though I acknowledge that it is a good system.
The e-locker appeals to me more and the unlock from forward to reverse doesn't seem like a big issue especially in practice as if you were rock crawling and you had to start to reverse with a wheel in the air the transition from forward to reverse would be accompanied by a foot firmly on the brake.
But the Detroit locker, with some research, has moved to the front of my list of what I would want. So in practice in 2H and the hubs on auto you are not going to know you have a locker. As I understand it 99% of the time the front diff is stationary. That means that you will have no funny business on the road. When in 4H or 4L with hubs locked I am 4x4ing and the clicking and other associated issues will not be an issue. The unlocking around corners seems to be a reliable feature and the competition guys have a detroit upfront with on demand lockers at the rear as they get better turning that way. Lockrite seems to be a more gentle system but looks like they may not have a patrol version?

I have them front and rear in my old Discovery 1. They are hard to beat for over-landing. They give incredible stability to the vehicle. I happily drift a lifted fully loaded lifted vehicle on dirt roads with this system. And you won't even realise you've blown out a tyre (I know, I've done it). You can put two wheels on tar, two on dirt, put it in first low range and floor it - with no wheel spin at all. They're always there always working - fit and forget. They only need 5ft/lb of resistance to operate. So if you lightly apply the brakes, they immediately work. But you can break your CV joints if you are silly with the brakes. In real terms they actually add far more value and utility than just about any other kind of locker. I understand that they are now also available for some vehicles with a switchable full locker option and if so you then would have the best of both worlds.

PS: They are NOT limited slip diffs (although often referred to as such) - they are gear operated (there are no clutch packs) torque biasing differentials - they do not limit slip but direct the torque to the wheel that has the traction. They are practically unbreakable and do not wear out.
