it just a tist of one side of the hubs, or do you have to twist both of
them? Also, any experience with them would be appreciated. I've been
wanting to go on some of the trails the jeepers here go on, but they seem to
be running lockers most of the time. I of course will try without first,
just thought I'd hear some info on them from the crew.

It doesn't look like anybody picked up on this, so I'll answer your
questions myself. There is only one locking hub, the long axle side. It is a
very simple, low tech and as a result, a very reliable unit. It works on the
concept of opposing springs, a 200 ft/lb locking spring and a 60 ft/lb
unlocking spring. Essentially the long axle slides into the center part of
the diff to lock the unit up. The unlocking bolt compresses the 200ft/lb
locking spring and the 60 ft/lb releases the axle and hence unlocks the diff.
I carry them because they are low tech and effective (and I like diffs).
One of the problems with fully selectable locking diff such as an ARB, is
that they are a very complex and expensive devices. They have a mechanical,
pneumatic and electrical systems and as a result are more prone to problems.
This manual diff lock is only mechanical.
The only disadvantages of this manual unit is that the diff lock is not
cab controlled and and the locking hub protrudes slightly beyond the wheel.
As far as the cab controls go, in my opinion its not a big deal. The unit is
extemely stout (4 pinion carrier and EN25 24 spline axles) so if you don't
feel like unlocking it off road - leave it locked, you are not going to
damage it. Besides a nifty, modern, high tech looking, lighted ARB switch
looks so out of place in a Series Rover!
The slightly protruding locking hub is easily solved by having some
awareness of it being there and as a result watching where you are going.
When was the last time anyone ran a front locking hub into anything. I've
never done it.
I just received an batch of them in so I do have them in stock at present.
