Rear end diff

Anyone can tell me how to tell what gear ratio I have on my 2001 2wd. Is there a code on the tag?

Code should be on the tag.

Check out the Super Duty FAQ for a calcualtor that will help you determine the ratio.

If it is powered by a PSD then you have 3.73.

Looks like you need to update your signature, too.

Thanks, the question is actually for my buddy. He said it a has a code of C1 on the tag. Can you tell if it is 410s or 373?
