Lowest numerical factory 14ff/dana 60 gearing?

[Bookshelf]

I've seen one tons with 4.56's and 4.10's, a few with 3.73's. Did they ever come with 3.54's or 3.42's? I have 4.10's in my crew cab and am going to gear down for the Cummins thats going in, and was wondering what was out there. I know I can get 3.54's for the front, I haven't had any luck finding those for the rear though. Thanks

I know there were 3.42's available for the 14ff.

Probably listed on dremu's brochure page, check out the specs for various years.

I know next to nothing of the 60's, but the 14FF could be had as low as 3.23 in 3/4 tons (w/4WD)

3.54 is the highest ratio (lowest numerically) that a dana 60 can take.

Dana 61's can take higher gears than that, which is why they exist (the OEMs wanted high gears for the diesel trucks).

The Dana 61's came w/ 3.07's for the 3 speed Auto Cummins trucks. I should have phrased the topic as asking if 3.54's were available for 14ff's, since they'd match the front then.

Looks like 3.42 or 3.73 on the 14 bolt which means you will have to use one of your dana 70's
