56 1/2 ton differential gear ratio?
I'm going to replace the dieing Dana 41 that's currently in my 46 1/2 ton pickup. The original banjo apparently gave up years ago. I've located a Dana 44 from a 56 1/2 ton that seems like it will be an easy fit compared to anything newer. There is't a tag on the 44, anyone have an idea what the original gear ratios available for the 56 1/2 ton were? I'm wanting something a little more road friendly than the 4.27 in the Dana 41.

Re: 56 1/2 ton differential gear ratio?
there iare two more, a 3.92 and a 4.09, got the info out of my 56 ford truck factory manual, check on some of the big fords and lincolns around 70 to late 80s for a 9 inch, a lot of good ratios in them, most will fit with just a little modifacation

Mine came from the factory with a 3:73 and it's stamped on the nomenclature plate at the door seam. I have never found that ratio in my 56 Ford parts book!

My 56 is a 2 wheel drive so I'm assuming that some of the 3:73 were installed in the 2 wheel drive trucks. Would this be an option from the factory?
