General Motors is discontinuing its Chevrolet Silverado 4500HD, 5500HD and 6500HD medium-duty trucks, marking a major exit from the Class 6 and Class 7 commercial truck segment in North America.
Production will end on 30 September 2026 at the International Trucks facility in Springfield, Ohio, following GM's decision not to renew its long-running manufacturing agreement with the company. The move has triggered wider disruption across the commercial truck supply chain and raises questions about the future of purpose-built medium-duty vehicles.
