I got a 12 bolt rearend that i'm plannin on puttin in my truck and i was told it had a 3.73 ratio in it. Will the ring gear have a number to identify it or if not what method would be the best to identify it without taking it out? thanks in advance.

 

you could turn your wheel and count how many times the ring gear turns and that would give you an approxiamate

 

Will the ring gear have the number of teeth for it and the pinion stamped on anywhere??

 

i dont think so

i along with many others on here are primarily gen3 knowledgeable, but there are a few gen1 guys on here and some have knowledge of both

ive learned the little i know of gen1 from listening to my dad
