Diff locks lock you diffs and supply equal torque to both wheels what ever situation you find your self in.

There are three general types of lockers.

Air lockers
Electric lockers
Auto Lockers

Air lockers are made by ARB and TJM, they are selectable, so you can turn the locker on to lock up the diff when you need to and then turn them off and the diff will opperate the same as normal. Great if you do a lot of road work as you can turn it on only when you need it.

Electric lockers are the same as above, but usually only found as a factory extra for certain vehicles such as Safari's, Cruiser's and Pajero's.

Auto lockers are a small unit that replaces the spider gears in your diff carrier and are always engaged. They unlock when you drive around a corner on the tar seal or other hard surfaces. Not that good if you have one in the rear diff and use your vehicle as your daily driver, but fine if you run one in the front diff and have manual free wheeling hubs. Saying that though, plenty of people run them on the road in the rear diff with out any hassles, its just adjusting how you drive slightly.

The rear diff is the preferred diff to run a locker in my opinion, others prefer the front diff. I run an auto locker in the front of my safari and it works bloody well.

ARB air lockers are about $1500 to buy off the shelf, and cost about another $1000 to have professionally fitted. They're are a bit of a mission to fit as you need to mount a compressor, wire in a couple of switchs, run air lines to the dif, drill holes in the diff housing, swap out the carrier, set up the diff (lash etc) with the new ARB carrier. Big job. Same with the TJM.

There are no factory electric lockers available for zooks, zooks never ca, outa the factory with them.

Auto lockers are readily available and pretty cheap, and easy to fit. There are several makes, Detroit, Lock Right, Lokka etc. Amoungst those makes are several differnt types of auto lockers from a simple kit that replaces the spider gears to full carrier replacement options. My opinion is that the Lock Right can't be beaten, but Detroits are good, and the Lokka not so bad. They are all largly the same designe, just build and material quality varies from what i have been told. I would go for a Lock Right if it was me. I have two, and they are sweet. To in stall you just wip the diff head out, mark the bearing adjusters etc, pull the carier out swap the spider gears for the locker, throw it back together,check the lash is stil the same, throw the diff head back in the vehicle, and go wheeling 8)

Loss of steering primarily comes from the front being locked. Thats why a lot of people prefer ARB as you can unlock, turn and then lock again.

An electric-locker is available for the samurai. Made by KAM differentials but I don't know price, but bet it will be something like two years earnings, plus your wife and first-born!

There's a review and highly detailed installation guide on izook.com

The shorter the wheel base, the more affect cross axle diff locks will have on handling.

As a side note, those of you who are reading this thread and think centre diff locks are the same as cross axle lockers, they are not. If any one asks, I will spell out the difference.

I suspect you are just using fancy-pants words for a locker? :) cross axle referring to the fact it ties across the axle?

A centre diff lock is found on full-time 4WDs (and Ladas :P) where they use a 'third' diff between the front and the rear for torque balancing on hard surfaces. This diff can often be locked to give true 4WD.

Fancy pants, or correct terminolgy. If you new to 4wding the abbreviated terms we take for granted can be confusing. Just trying to help :wink: .

Ya can get bolt-in zuk cages from the states, but they would cost more than your truck. :shock:

If you want us to recommend someone who can build one it would help to know where you are. :wink: I think the 4wd assn website has specs for cages for trials competitors, that would be a good place to start for some design tips.
