count the teeth on the crown wheel, count teeth on pinion, divide crown number by pinion number, answer is the ratio

If it's on a Nissan then the Trans anxle number with tell you. The last 2 numbers are the ratio. eg HG41 is a GQ (or GU or a Terrano) with 4.1 ratio. etc
Nissan Terrano coilovers, turboed VH45, Safari axles, and some other stuff.

jh37.9 jk299 37 divided by 9 = 4.1?

set two

h35.8 bt47 35 divided by 8 = 4.375?
