Moderator's Note - Copied from 80-86 where title was "1980-1986 axle code chart needed"

I have been looking at a few 1980's trucks for sale around here, but am often unable to determine the axle ratio and weight rating. I searched a couple times, but found nothing.

Could someone please post the axle code chart for the 1980-1986 F250 and F350 trucks and identify what year manual the chart was taken from? It would be greatly appreciated.

My expertise is 1967-1979 trucks, and that is all I have manuals for...

You'll notice that some of the codes that are the same between the early and late books don't necessarily correspond when it comes to what axle they indicate. The same goes for alot of the current online decoders. Same code, different meaning.

 

Exactly Right.

And makes it confusing as heck.
