Front and rear diff differences

Are the ratios different on the the front and rear diffs of the Suzuki Jimny?particularly the the G13bb version and are the differences made up for in the transfer box or is there a reason for the differences. I know you can't drive on the road in 4wd. Wud towing a load a short journey in low range do much harm.like 100 mtetres max I mean.
I know very little about 4x4s as I am new to it.i bought my Jimny last November and rebuild my Engine,done clutch and electronics and upgraded radiator and just worked out the bugs lately so only getting to drive it now

if you have stick transfer box
you would benefit from the 2low modification maybe

Is that a big job? I heard there are transfer boxes out there with lower low and higher high ratios with pots as well. Probably hard to find.im just wondering why Suzuki didn't use same ring gear I never both axles.the the different ratios a benefit for off road traction or something?ive seen a video wher a Jimny toes a lorry with 10 Jimny son the back in low 4wd on tarmac.it must be a tough machine

I just watch the video.wow that's a class mod.how is the 4wd engage so?is it a solonoid or something.

Diff ratios should be the same front/rear
4wd system works on vacuum with solenoids
