NHTSA's summary

This communication addresses a specific issue related to the DCB tube frame of trailers. It provides a summary of the potential problem, recommended actions, necessary parts, estimated installation time, and detailed installation instructions. The purpose of this communication is to guide customers and installers through reinforcing the trailer frame to prevent damage due to improper loading and overweight capacity. The issue is that customers have been improperly loading equipment and potentially exceeding the trailer's weight capacity, leading to damage in the lower frame material of the DCB tube frame trailers. The improper loading and excessive weight can cause structural damage to the trailer, compromising its functionality. The communication aims to provide a solution to prevent further damage and enhance the trailer's load-bearing capacity. It instructs customers and installers on how to upgrade the trailer by reinforcing the frame using the DCB Upgrade Kit. This communication ensures that the option to reinforce the trailers frame is available, thus improving the trailer's durability.
