I found a gearset, possibly from a Ford, it was marked 50-11(4.55). I don't know too much about anything, but 50 is a lot of teeth. I didn't measure the ring gear.

Anyone know what these gears are from?

Not to be a complete jerk but<<<<<<<<<< ARE YOU OUT OF YOUR MIND>>>>> the gear ratio.......... all you gave us was the gear ratio........ It could be out of a FAWKING YUGO...

You know what's sad ... I saw this when it was first posted and didn't flame in fear of being flamed back for flaming a newbie. I guess I've just spent too much time in the Chevy forum. :D

J. J.

I wasn't going to ask as I knew there wasn't much info to work with, but being out of my mind I thought I'd give it a shot anyway. It's like asking "I saw a blue truck, anyone know what it was?"

A guy here buys old Ford trucks, tears them down and sells the parts. I was browsing through his gearset collection and these big gears caught my attention. He couldn't remember what they were from.

I guess you had to be there

EDIT: Found out they are from a li'l ol' Dana 44...now I see why you guys didn't know:) Did Yugos come stock with D44s?:)

that is a dana 44 tooth count for 4.55 ratio

Yeah but it like there was question the other day about how you couldn't have a 4.50 ratio.. yea you can.. They used to do lots of stuff and if you do a search for antique cars and gear ratios (no offence gearman) but you can pull up ratios till the cows come home on packards and desotos and flipping anything ever built. so to just have a 4.55 ratio gear set it could be out a heavy truck built in Borneo..

I used Yugo because they are sooo cute and worthless.


Now if it said spicer you could narrow it down a little.

he said he was at a ford place so i used that bit of info to no what he was asking and besides YUGOS are front wheel drive :flipoff2: and besides that i cant think of anyother manufacture that uses that tooth count anyway packards and desotos used spicer to make there shit also as well as ramblers so all i needed to answear his ? was the type of yard he was in and what the tooth count was :D

Ok OK OK ... I never said you couldn't do it. or that you were wrong...

OK, now that he knows they are from a D44, and they are 4.55/4.56 ratio.... any whay for him to tell if they are RC or standard??


Jekyll, if they are RC.... I my be intrested in them if you want to unload them.....

spicer never made rev 4.56 thats a aftermarket ratio

OK, I think I had heard that before... thanks for the confermation.



However, unless I missed it, he never did say it was a Spicer gear set he found (or did I miss it), so it *could* be an aftermarket...


to the point however, how can you tell from looking at a set of gears if they are RC or standard? Having not examined RC gear sets much, not compared them... are they stamped with that info?, are they so much blatently different from a standard set that it should be obvious...


not trying to be an ass.... just learn a little more, expecialy handy when I'm cruising the swap meets....

I was hoping they were rev cut too, but then I never heard of any Ford 4x4 with 4.55 gears. Then remembered Spicer never had 4.55 RC. soooo...

nope, I forgot to mention in the first post they were spicer. Sorry to be slightly misleading, too...I shouldn't have said "possibly from a Ford", but "most likely". I thought non-newbies were mind readers.

I figured that someone who has been paying attention to gearsets would have seen that ratio. Again, I should've said Spicer. How appropriate is it that someone called "Gearman" knows about gears?:) I could have just said "50-11" and he'd have it narrowed down to 3 manufacturers.

Rev and std D44 4.88 gears
