This is from an
official Chevy press release:
The upgraded driveline includes robust front and rear axles, including an 11.5-inch rear-axle ring gear on all 2500HD models and 3500HD models with the 6.6L V-8 gas engine; and a 12-inch ring gear for 3500HD diesel models. Also, 30-percent-larger-diameter prop shafts provide greater strength with the high torque output of the new 6.6L V-8 gas engine and the Duramax Turbo-Diesel.
Now, I'm even more confused...
