Reduction gears for Jimny

Dear members, I would like your valuable opinions on the reduction gears for the Jimny.

As we all know that unlike the diesel powered 4x4s, the Jimny 4 Low ratio is not low enough. Compounded by the dismal torque, it makes the Jimny very bad at crawling in offroad situations. In fact the Jimny does not crawl at all.

Therefore, as a solution, is it a good idea to install reduction/ crawler gears? Are they available in India?

This is what I have found online:
