The tag's rotted off on my rear diff & I don't know it there's supposed to be one on the front, but if there is it's gone. What were the most typical ring & pinion set-ups for a '94 F-150 4x4 with a 5.0. & is there any other way I can find out what my gear set-up is?

 

There should also be an axle code on the driver's side door frame.

This link will help you translate the code into what ratio was installed at the factory:

I just want to make sure I understand this corect: My code is 19, so I have 3.55s? Thanks for the response, BTW! That definitely cleared things up! With that chart we also found out my friend's F-250 has 4.10s(code 35)!

 

there should be a label on the back side of your axle support arm you can use for the front

 

yes, 19 is a 3800lb capacity axle w/ 3.55's

 

Thanks a lot guys! Do you think 3.55s are good with my lift/wheel/tire combo?
