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.

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 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:

Here is another list of ford codes, but no 2.33

I've searched for this "mythical" long ratio sproradically for years and never found a tag code.

That is all.
