About This Item

This document establishes a minimum performance criteria for conventional towing systems for the towing interface between a tow vehicle and trailer up to 9072 kg (20000 pounds) Gross Trailer Weight Rating. This does not include weight distributing hitches. This creates the minimum performance criteria for the hitch, trailer attachment structure, coupling, and tow vehicle attachment structure. This standard may be used as a regulatory guide in the selection of products covered. This document is intended to be used voluntarily by the industry producing these products. With the increase in chassis capacity in the automotive industry, there is no minimum performance standard for conventional towing systems from 4536 to 9072 kg (10001 to 20000 pounds). This standard reflects a more modern approach using fatigue life cycle testing and creates a Class 5 rating. This standard is intended to replace only the weight carrying hitch test loads in SAE J684. This does not apply to the weight distributing hitch loads.
