If the Duramax was going to perform "better" with a 4.10 axle, that's what it would have. Clearly, GM thinks a 3.73 is best as they've stuck with that since the Duramax was introduced in 2001. 3.73 is and continues to be the only axle ratio available in a 2500HD or 3500 for the past 16 years. That says something.
With Ram, they have had 3.21, 3.55, 3.73 and 4.10 (4.44 and 4.88 in the C+C units) paired with the Cummins from 2001 until now.
Ford has had a similar spread. 3.31 to 4.30 with the powerstroke.
