What is AAM rear axle rating? How does this compare to rear GAWR? He has a 2012 2500 HD D/A 4x4 crew cab and stated his specs are as follows: GVWR=10,000 lbs., GAWR(front)=5200 lbs., GAWR(rear)=6200 lbs.
His E rated tires are approx. 3000 lbs. each = approx. 6000 lbs. max capacity. How can a rear axle rating alone exceed GVWR?
Now, I would never try to compare my motor and trans.(6.0/4L80), to the 6.6 Duramax/Allison. However, the issue pertaining to this entire thread is PAYLOAD correct? His truck weighs somewhere in the range of 7,200 lbs.
10,000 lb. GVWR - 7,200 lbs. truck = 2800 lbs. payload.
Those 2500 HD D/A trucks are certainly pullin' bad mamas, but many forget the additional weight of that setup. Unless I completely missed this, am I really being that "silly" when comparing them in terms of payload??
