why would any company object to free advertising of there products :huh:

Because if free discussion were allowed here they would consider it rather negative advertising

Draw your own conclusions :whistle:

The jimny transfer uses epicyclic gears to achieve low ratio.
Modifying these is too difficult and expensive to be cost effective.
The only option really is to change both the sprockets (as it is chain drive). There is a limit to the change, as there is no chain tensioner or adjuster, so the chain has to fit perfectly without hitting the casing.

This will affect both high and low ratio equally though. (what you want if you have big tyres, but it can only accommodate mild changes)

So most people opt for an sj transfer box (gear drive) and modify it, the easiest way is a rocklobster conversion, which mates gears from early and late 'boxes.

Replacing the gearset in a jimny transfer box means you still have the weak part in the link ie the chain, that's why these conversions are not popular.
