I’m new to this ranger thing. Where would I find what gear ratio I’ve got on my truck without pulling it apart and counting teeth?

Break it right the first time. Fix it better the next time.
Open your driver side door and look for the white id tag inside the door jam. Look under axle and see what the code is.
