DANA 60 ring gear question
I have two questions.
First: what is the diameter of the ring gear in a Dana 60 rear end?
Second: I have an 1986 F250 4x4 with I believe the 8600 GVW, which I believe was the highest GVW for a F250. What rear end options where available for these trucks?
The reason I'm asking is because I have thought for sometime my Ford was a Dana 60. I believe when I bought a pinion seal it was for a rear end with a 10.25" ring gear. I just bought a ring and pinion for my Dodge which is suppose to have a Dana 60. Well the ring gear I got was 9.75". My understanding is that all Dana 60 RING & PINION GEARS ARE THE SAME.
Any help or ideas would be appreciated. Thanks

It may be but I can tell you that a Dana rear end and a Ford 10.25 can be IDed by looking at the rear end case. On the back side of a Dana you will see a deep "hole" on the carrier housing. between the cover and the tubes. Dana axles require a case spreader to build them and that is what these "holes" are for. The 10.25 don't have them. They don't require a case spreader.
You also get those tall gears in a Dana 60. I have a Dana 61 in an 83 F250 that has 3.07 gears. It has a 6.9 and a T-19 in it. I have to down shift at most hills with a load but I get 22-24 MPG on open road. It is a trade off.

You just told me I was right in what I thought in regards to IDing them. Yea, The lowest I can go is 3:54s. It should give me a little better mileage. I get 10.5-11.2 MPG now I hope the 3:54s will give me around 14 MPG. It's a D250, 2wd, 4sp, 360 4bbl, Holley 4175 Spreadbore, with a covered utility box. So We'll see.
Thanks Again.
