SAE J701-2017 PDF

Scope: The information in this SAE Information Report is the result of studies by the Automobile Manufacturers Association@ American Trucking Association@ and Truck Trailer Manufacturers Association@ to achieve interchangeability of equipment which will comply with the legal dimensional limitations for the majority of states and yet permit increased loading space within these dimensions. This in no way supersedes other information in the SAE Handbook on this subject. Some cases will require more care in application allowing splash shield clearance at trailer support interference points and positioning fifth wheel to allow trailer swing clearance on an 11% grade. All dimensions are given in inches. NOTE: Fifth wheel height = 48 (10.00 x 20 tires) standard unless otherwise specified. For tubeless and low-profile tire equivalents; see the Tire and Rim Association Standards
