Here’s what’s known about GM ending production of the Silverado HD lineup as of mid-2026.
Direct answer
- GM has announced it will discontinue the Chevrolet Silverado 4500HD, 5500HD, and 6500HD medium-duty trucks, ending the production partnership with International Trucks. Production is scheduled to wrap up by September 30, 2026 at the Springfield, Ohio facility.
Context and key points
- The Silverado MD models (4500HD/5500HD/6500HD) were developed and built in collaboration with International Trucks, with final assembly in Springfield, Ohio. GM is not renewing that manufacturing agreement, effectively ending the Silverado MD line in this configuration.[3][4][7]
- The related International CV Series medium-duty trucks will also wind down, with its production ending earlier in September 2026, as the plant’s output shifts away from these programmes. This underscores a broader shift in GM’s medium-duty portfolio and manufacturing strategy.[1][7][3]
- The Ohio plant’s long-standing role in both Chevrolet Silverado MD and International CV Series production has been a focal point of the disruption, and the plant itself is undergoing ownership changes in 2026 as part of the transition.[1][3]
- Market implications include potential impacts on fleets and body builders who rely on the Silverado MD in the Class 6/7 segment, and questions about how GM might re-enter or reconfigure its medium-duty offerings in the future.[5][3]
Notes and caveats
- Multiple outlets corroborate the September 2026 end date, with GM indicating it is evaluating future portfolio options for medium-duty vehicles, but no replacement product has been confirmed as of this date.[4][3]
- Some coverage emphasizes the broader consequences for the Springfield plant and the supply chain, given the scale of the MD programme and the recent sale/transition of the site.[7][1]
