I'm new to the forum and keep hearing Rocklobster and I wonder what the benefit is in doing the conversion? Seems a lot of work so it must be beneficial, I just don't know why.
Please could someone educate me.
Thank you.

The standard Transfer box is ok but if you like to play seriously, then you want more engine breaking, to beable to run larger tyres and also to beable to run slower when in Low .. to give you more control (and reduce the chance of breaking something)

As has been said, the slow speed you can travel at due to the lower ratios makes it more controllable, puts less strain on components and makes it far more comfortable.
The engine braking caused by the lower ratios enables you to go down slopes slowly without the use of the brakes and is so much safer.
Climbs can be done slower and with ease rather than resorting to the old Suzuki momentum method of flooring it!
It will reduce wear on your clutch as you would have to slip it to compensate for the high standard ratios.
It has about 10% lower high ratio which compensates for bigger tyres.
They are one of the best mods you can do to a Jimny.

When in Low Box it basically it turns your 1300cc Jimny, into a 3.5litre monster.
In Low box i only pull away in 3rd or 4th - only use 2nd or maybe 1st when going down hill (no breaks, no clutch suffering ) ...
If you can afford it - do it!!
Only problem with a 6:1 Low box, is i can only do 15mph flat out in 5th... but the power low down is awesome.

I see that here everybody is mentioning only the modifications in T-case in order to lower down your gear ratio. As I know is it possible to use also modification in axles by means of new pinion shaft and new crown ring. Did anybody use this method to lower down the gear ratio and to reduce the stresses on rear and front axles.
Please look here, what I mean: www.calmini4x4.de/538-1-Ring-Pinion-Kit_1

and in 5.1:1 ratio. I have my cousin using them in his jimny. It is not a very good option because you will
always have to open-close your diff avery time you want to make an adjustment etc.
If you are doing a lot of miles it is not recomended.
If you have the non vvt model then you can install the vvt model diffs. This will give you a -12% reduction.
We have a friends jimny mod2002 with vvt2007 diffs and runs 235-75-15 without any other transmision
mod. The price of the vvt r&p is about 250euros per diff from a scrupyard and for the 4x4art diffs is 350e
per diff.
The costs are the same by choosing one or other but you will have more benefits by installing a sami
t-case with gears.

Now I know the right way to update my Jimny. I will do it with rock-lobster or even rock-crawler.
It will be more expansive but as you said the benefits are bigger.
Cheers
