If you want a ratio less than 3.54
What would it take to adapt a
Dana 61 to a 1995 Ram?

Is my fuzzy memory correct that you can get 3.07
only by going to a Dana 61 housing?

Have the newest 9.25 diffs with the modification using lower friction ball bearings
from around year 2009 onward
Also done away with the frequent pinion bearing seal failures
That plagued Ram 1500s from 1994 to at least 2001?
