Tone ring tooth count

[IDIoit]

hay folks, im looking for a tooth count on a sterling 10.25.
the specific truck is an 87, but I think there all the same.
ive tried searching, and no dice. I did find a 52 and a 60 tooth tone ring for our trucks, but I don't know if that's what we got.
anyone shed some light?

im trying to program a electric speedo

That doesn't have any hard teeth count, but it is a quality picture that should get you a count.

Here is some more detail, with a part number the 4B409 which will get you a Ford number that sends you down another rabbit hole of images and purchase options but still nothing with a definitive tooth number.

I saw countless people pay that 3/4 and 1 tons all had 120.
I guess you could pop the cover or the sensor and go to town counting. Lol

I agree with @79jasper although I also found 102 referenced though the 120 seems to be a bit more mentioned. Sadly I cannot find anything concrete. Sorry

Here is another and if I counted right it is 102. Does it matter that the arctec are hub mounted and it mentions the Dana 60? You really asked the hard question here....

I have a late 1994 carrier, gears, and tone ring set down in the barn I can go count if you’d like. It was out of a 94 small block gas 2wd king cab F250, 3.55s open diff

I have to re seal my diff. I’ll pop the cover and count it for you

the tooth count is 120 on the rear tone ring.
found the info from a guy on the net, confirmed by the engineering folk at isspro.

Woohoo. My Google-foo was right. For once. Lol

my googling only found a 52 and a 60 tooth tone ring, which was obviously not stock lol
