I was trying to figure out the gear ratio on my 92 F250. The tag says it has a C9 rear axle. My owners manual doensn't list a C9. It has a C5, B9, and H9. Since everything with a 9 in the second place has 3.55, I'm assuming it has 3.55's. Can anyone tell me what it is for sure, though? The only thing I know for sure is that it is limited slip. Thanks.

That table is helpful, it would be even nicer if it listed axle type and capacity as well.

 

It almost sounds like the free resource on the Internet that was given to you for free by a stranger out of the kindness of his heart is now not good enough for you for some reason. Your owner's manual has this kind of information, BTW.

 

First off, I started off my saying that it was HELPFUL, and I meant no slight to johnsonswamp - if any was taken by him, my apologies TO HIM. I just commented that it would have been nice if that site had included the other information as well.
