I'm wanting to know the ratios for my H55F and transfer case in a 85 aus spec middy with a carby 3F and what other H55F/A440 transfercase ratios there are. I've found two low ratios 1.959, and 2.488 but not sure what cars had what and if i've already got the 2.488 ratio low range

cheers

According to this, all H55f after 86 had 2.296 low in the t/case. If yours is an 85 ,it maybe a 1.9.

I wonder if the low ratio of 2.296 has the 38mm idler shaft and the 1.9 has the 34mm?
