Chronology
Predecessor 7400 and 7600 Series

The International WorkStar is a line of severe duty trucks made by International Truck.[1] The WorkStar is the successor to the 7400 and 7600 series trucks produced by International. Starting in 2008 the "thousand series" name was dropped in favor of the WorkStar. This change was reflected in the physical construction of the truck in the form of a new hood and grill along with increased Maxxforce Engine options.[2]
