Hi all ive got a 2005 with the vvt push button type transfer case. im also running 30in tyres. Ive got a transfer case here out of the early model jimny(stick shift type) that has had the reduction gears changed. So ive spun the input shaft and i make it out to be about 1.7:1 in high and 2.7:1 in low. Can someone please help crunching these numbers to see what sort of reduction im going to have? I dont want to fit it if its not going to suitable. I do want reduction but how much this ratio is i do not know. Rear axle ratio i believe is 4.3:1. Also will the front and rear diff centres out of a seirra fit my jimny?? Would i have to change axles ? The front and rear housing has 8 bolts if thats any help .

The most common gear reduction for a standard Jimny transferbox is a 25% reduction, so that's probably what you have. Also makes good sense as the standard low range is roughly 2.2:1
