Gear ratio again!!!

[chaka73]

I'm sorry but I forgot how to figure out the gear ratio, my friend has a differential for sale, I opened the cover and counted the teeth, the ring has 43, and the pinion has 23 but I dont know how to figure it out any help thanks.

LOVE MY GREEN GIANT!!!

you must have counted wrong cause that would leave a ratio of 1.87 to 1 or or a 1.87 ratio

That is wrong. I think the lowest ratio I've ever heard of in a Chevy truck is 2.56.

once you recount the gears dived the ring gear by the pinion to get the ratio

If it is a GM or Richmond gear set, it will have the ratio or teeth count stamped right into the ring gear. On the GM unit it is b the serial/part number.
