I'm trying to figure out what gear ratio I have in my 92 YJ. It is a base model YJ that probably had NO options when new. 4 banger, 5 speed, and it had the smallest wheels/tires. Is there an easy way to find this out?
Crawl under there and look for the metal tag hanging on a bolt on the diff cover. First numbers will tell the tell. but you are running a 4:10 gearing I am pretty sure. Tug
You should have 4.10's. I think that the 4.88's gears are the way to go with a 2.5 and bigger tires. The lower the gear the better if your crawling rocks. And if you need more power.
