Wondering what the rear axel ratio is for our Entegra Odyssey 24B it's on a 14,500# GVWR chassis with a GCWR of 22,000#. It is supposed to have a Dana rear axel, but no specific ratio is listed in any of the specs. None of the stickers appear to have an axel code on them.

It's either 4.10 or 4.56; I think the E450's come with the 4.56 axle ratio as standard, and quite possibly don't have any other options for the ratio. A limited slip differential is an available option (that I would guess you do not have).

Google is your friend. Search:

"2022 Ford E-450 Stripped Chassis specifications"

They should be the same for 2021.

All E450 gas motors have 4.56 gears. It’s a modified Dana 80 axle, with 10.75” gears since 2007.

Look on the inside of the driver’s door jamb, ours is just above the door latch. It is an ‘official’ FORD sticker for an incomplete motor vehicle. Lots of information on it for that particular chassis VIN number, Axle rating, tires that were originally installed, tire pressure for each axle as rated.
The bottom line, middle gives the axle code as installed by Ford, you will have Google Ford axle “83’ (my unit) for the specs.
It also gives the original Ford wheel base, in MY case it is 158”, Winnebago extended ours to 195” and also extended the frame at the rear.

Well ... either me, or Ford, or internet posters ... are confused!

I always thought (from an earlier spec I no longer can find) that the Ford 2005 E450 cutaway chassis under my 24 ft. Class C had a 4:56.1 ratio differential in it. It sure pulls like it going up grades and when crawling along on rough dirt roads.

HOWEVER, my door sicker shows a rear axle code of "83" and per this chart the ratio is - 4:30.1! What is going on anyway?:

Hi Pnichols I did see that website, but I also found another fordtrucks..., site that listed the 83 axle for the E450 dually as a Dana with the 4.56 gears. It does seen strange/confusing that there appear to be two different axles with the "83" label. I'm quite sure that mine has the Dana with 4.56.

Yeah ... I saw a lot of confusing info when doing my research. I noticed that the same number designator was often used for different Ford vehicle models ... so "83" may not have been a particular unique differential type used in Econoline E450 models.

For instance, in that link I posted above the 83 number says in the far right column that it's what's used in an F350. How closely is an F350 related to an E450 such that the same differential would be used for the two different weight classes?
