Gm Ends Silverado Hd Production, Drops 4500HD, 5500HD, 6500HD
gm ends silverado hd production later this year, ending the Silverado 4500HD, 5500HD, and 6500HD line tied to International Trucks. The move removes Chevrolet from a medium-duty truck segment built for towing companies, utility fleets, contractors, and equipment hauling.
Just over 1,200 Silverado medium-duty trucks sold in the first quarter of 2026, a thin number next to Ford’s F-650 and F-750 lineup. That gap helps explain why General Motors is stepping away from the agreement instead of extending a program built around the Duramax 6.6-liter diesel V8 and Allison transmission.
Springfield, Ohio sale
The production setup was tied directly to International Trucks’ Springfield, Ohio, facility, and that plant was sold earlier this year. Once that arrangement changed, the Silverado medium-duty trucks lost the manufacturing base that had carried the lineup.
GM’s decision also leaves Chevrolet with a narrower commercial-truck footprint. The brand is staying in the segment through its Low Cab Forward lineup, which continues through an Isuzu partnership, but the heavier Silverado trucks are ending later this year.
Ford F-650 and F-750 gap
The sale and the discontinuation point to the same pressure: a low-volume line tied to a plant that no longer sits inside the same agreement. For fleet buyers, the practical effect is that the Silverado 4500HD, 5500HD, and 6500HD are on the way out, while competitors with larger medium-duty volume keep the category to themselves.
Fleet operators that have relied on these trucks now face a shrinking Chevrolet option set before the end of the year. The remaining commercial path for Chevrolet runs through Low Cab Forward, not the Silverado medium-duty trucks that are ending production later this year.
