Chry 8.25 factory gear ratios

hey all,

i just upgraded my d35 to the 8.25 but i have to drive it in 2wd all the time because i dont know it that ratios are the same. i took off the diff cover and the ring gear had 33 teeth and the pinion had 14. if my math was correct thats a 2.36:1 ratio. I didn't think that there was such a gear set up. was currious what or how to check it correctly.

Thanks for your help.

I think Most 8.25's have 3.55 in them if it came with a automatic trans.

The ring gear has more teeth, probably 43.

That would equal out to 3.07.

Recount, divide the ring gear by the pinion, you get the ratio.

No cover tag?

If it's a manual (ax-5 or 15) then it's probably 3.07, automatic then 3.55 unless it's a factory HD towing package - can't remember that one, 4 cyl manual was 4.10. The 1997 factory service manual doesn't list 3.07 for the 8.25 but mine has the tag with 3.07 printed clearly.

there are a couple of choices when it comes to factory gearing in the 8.25,

6cyl/auto/3.55
6cyl/manual/3.07
4cyl/manual/4.10
4cy/auto/4.56 - never actually seen one, the 4cy auto, but rumored to have exsisted

now a couple of people believe that the 8.25 came with 3.73 for a 6cyl HD towing package, doesn't exsist. But I would love to have someobdy prove me wrong. I would love to see a from the factory 8.25 with 3.73s and a limited slip or open. Any takers?
