AAM rates their axles in kilos in their technical documentation and lots of people don't do the conversion accurately at 2.2 lbs. per kilo and so do not get the actual 10,900 axle load rating but are off by 10%.
The GM 2500HD Duramax has a different rear axle than the 2500HD with the gas engine. My 2011 2500HD came with a higher payload rating than some of the GM 3500HD trucks. Lots of reasons why this is the case.
With my 2011 Duramax 2500HD the GM brake part numbers, front and rear, are the same as those for the 3500HD non-dually truck for ALL of the brake parts, including the rotors and calibers. The parts only change for 3500HD trucks with dual rear wheels. The dual rear wheels increases the GCWR by 4700 lbs. and so there is a possible need for improved braking with the DRW 3500HD Duramax trucks.
