Question about GVWR.

"The Gross Axle Weight Rating (GAWR) is the maximum weight that the designated axle system is designed to carry. It is set by the OEM and noted on the vehicle's original certification label. Again INCORRECT! The axle ratingnis specified by the axles manufacturer. They design and specifiy the rating of that single component. The body builder specifies the vehicles GVWR based on factors, among them I spelled out earlier.Alterers must determine whether their modifications affect the manufacturer's stated GVWR or GAWR. If they do, the alterer must specify the new GVWR or GAWR on the alterer's certification label (see 49 CFR 567.7). Note: A modifier or dealer should never accept an altered vehicle that does not have an alterer's certification label."

Sorry Don, but that is incorrect. Per US DOT and their definition of what they say the GAWR is, it is the whole axle system and not just the axle. The US DOT is the one who makes these regulations on what GAWR is so you cannout say they are wrong since they make the rule.
"GAWR
The Gross Axle Weight Rating (GAWR) means the value specified by the vehicle manufacturer as the load-carrying capacity of a single axle system, as measured at the tire-ground interfaces."
