Looking for 250 ring and pinion for 9" Ford .
-
The 2.47 gears are easier to find, especially if you need spares. Here is a set on that auction site, the seller also claims to have 2.50 gears as well. Tony

2.25+/- for a Ford 9"?..... I don't know of this gear ratio...... although I am old enough to know that I don't know everything.
I was looking at using a 2.41 GM axle out of a late 70s Firebird or a 2.29 GM axle out of a very late 70s Cadillac (both are 8.5" ten bolts)..... And then I was told that Strange Engineering makes a 3rd member for a Ford 9" housing that will accept GM 12 bolt gears....in the same conversation, I was also told that GM 8.5" ten bolt gears can easily be made to fit in place of Chevy 12 bolt gears (and vice versa)..... again, I do not know this to be fact but it may be something to look into. The pinion offsets on the custom Strange 3rd member are equivalent to Chevy though.... so if you did not have a driveshaft of some length, a housing with the right pinion side to side spacing would need to be made and (as in the case of our lakester) the pinion height to axle center line would raise the car up some.....

When I was looking for 2.50:1 gears for my 9" I gave Curries Rearends a call. They asked me how many sets I wanted! I had a set in a couple days. Seems they saved all the factory Ford take-outs. Good, used, and CHEAP! Hope this helps.

At speed week last summer while in the heat of debate over gear ratios...someone handed me a cell phone with some guy claiming he had several 2.25 ford nine inche gear sets on the shelf???!!!!???
I handed the phone to one of the crew to get the particulars...I got involved in something else....anyhow I can't find the particulars and even more embarrassing I can't remember who handed me the phone or who I handed it off to....

I thought I had located a set of 2.33s on a web site a while back. After numerous calls to the site owner and anyone else he could recommend, to no avail I gave up.
I think it was G Force that told me Ford listed them in their older Motorsport parts book but he had never seen a set. No one could give me any info on where to look next.

Ford did offer the 2.33 gears in a 13/35-tooth count and they came in big Lincoln’s of the 70's and not a 100% sure but I always thought they were 9 3/8” rear ends. Tony
-
The 9 3/8" Lincoln carrier will fit the 9" housing. Bolt pattern is the same but you might have to grind clearance for the bigger gear to fit through the opening into the housing. The gaskets are notched and will tell where to grind if necessary.

outstanding!!!!!!!!!!!!!!!!

13/35 tooth count? equals 2.33 ratio?.....a quick calculation says that would be about 2.69 to 1.... which, if that exists..... I would like a set
are you sure it isn't 15 to 35 ?....which does equal 2.33 to 1.... and i will take a set of these as well.
Speaking of this though.... does anyone know if there are any 9" Ford gear ratios somewhere in between 2.75 to 1 and 2.50/2.47 to 1.... like a 2.62 or 2.64 or something?

2.33 :-o I know where a bunch of Lincolns are any codes---how would one know what to look for? :?

Sparky,
Since this was posted I have spent about 2 hours using Search engines to find out about these gears. I cannot find any information on them. Also the ring gear to pinion ratio on the chart is wrong for the 2.33 as it comes out to 2.69.
Has anyone ever physically seen these gears?

Here is a link to some codes, but believe these to NOT be Lincoln:
http://www.woodyg.com/fairlane/finfo/fordrears.html
Here is another list of ford codes, but no 2.33
http://home.comcast.net/~petebre/maverick/FoMoCo_rear_ends.html
I've searched for this "mythical" long ratio sproradically for years and never found a tag code. ???
That is all.

I have a 1970 Ford manual that has the axle code for 2.33 on the door tag for 1970 models including Mustangs as being X. Tony
-
Just noticed on one of SaltRat's links it lists the same code for the 2.33. I would guess these gears are more common in Texas or in the mid-west where the roads are endless. Tony
-
the elusive 2.29 12 bolt gm only came in a 396 2 barrel car in an Impala or some none such---I gave up and settled on GM 10-12 2.28 Caddys
Just recently saw some 2.27 8.5 GM gears listed on EBAY---I have never seen any reffrence to them in any GM or Hollander my curiousity was NOT up to the 150.00 purchase and freight.
-
When they say "X" code, they are talking about the "axle" code on the door tag or sticker. If the rear end hasn't been changed, the door sticker will tell you what's in the rear without having to crawl under. It will also tell you if it's posi or not. A lot of 77-78 Thunderbirds and Cougars had 2.47s in them.

After I looked at the second link Saltrat posted, down at the very bottom of the page is a chart showing door tag codes. It shows a 2.33 for "F" code open and "X" code for locker.

77-78 was when Caddy had the 2.28 gears

from what I can glean, the 2.33 was in fact avaible in Lincolns.... it was a 9 3/8" ring gear.... the carrier etc does fit a 9" housing (and vice versa) but reliefs have to be ground into a 9" housing in order for the 9 3/8 gear to pass through.... The carrier and most of the parts for a 9 3/8" center section are NOT interchangeable with a 9" center section..... and th 9 3/8" differential USED ONLY 31 SPLINE AXLES.
This ratio was supposedly also available in some golf carts and/or other lawn type equipment that used Ford 9" rear axles .....
Now, apparently, there was also a 2.33 to 1 gear ratio available in the small (7.5 inch) Ford integral rear axle as well.... do not confuse the two....
Sparky.... if you find some diffs..... I want one...
-
The easiest big ring gear is the 8 7/8 Caddy with the 2.28 has 28 splines Had one in my Lakester that is now the rear axle for the truck a converted another center section to a frt axel for our 4x4 truck by changing the tubes out.

The information I was able to find was that the tooth count was 15 to 35..... and they were/are 9 3/8 ring gears.... happy hunting
-
This link has immediate access to about 10 or more pages of Ford axle codes.... It states the gear ratios, whether it was posi or not, ring gear diameter and generally states whether it was an integral rear axle or not...... however, alas, NO reference to the elusive 2.33 to 1 ratio..... except in a 7 3/4" diff.... nor does it have part numbers or part number suffixes

Okay.....So.....NOW..... I have decided that I want a 2.50 Ford 9" 3rd member complete and in usable condition without a rebuild..... NON posi with 28 spline gears... delivered to Bonneville Speedweek would be fine........ BTW..... I already own 2.47s and every other Ford and Richmond Gear ratio up to 3.00, so please do not offer me any.
What have you got and how much money?..... and I do have stuff to trade ...
