I don't have a CTD but my 2008 Ram 2500 with the hemi has 3.73 gears. They were alright with the little stock 245 tires. After I upgraded to 35" tires it's a little high geared and wish I had 4.10 gears. I know, talking about apples and oranges with the motors but just something to think about if you are the kind of person that likes bigger tires.
