What is the Gross Axle Weight Rating?
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. 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.
