Just to add to the confusion...
Dana 44, 1 5/8" dia ram, need a full 7 3/4" ram travel, 37" tires, PSC hi-capacity pump.
I think why I need so much travel is because I've got full strg capabilities. I've got Cage extended arms that allow full use of my steering and my stops have been backed way off so I can turn almost back to stock turning radius.
