JOST International began as a small business in the early 1980s, where we submitted the patent application for the very first steel cast fifth wheel coupling. Since our start in Grand Haven, Michigan, JOST International has grown to become a world market leader for fifth wheels and landing gear and an international supplier for the commercial trucking industry.
Though we’ve grown through the years, JOST International is proud to retain the same values and principles that launched our business decades ago — a dedication to safety and continuous innovation, and above all, a close relationship with our customers and our employees.
