Here’s the latest on GM’s Silverado HD production ending.
Short answer
- GM is ending production of the Silverado 4500HD, 5500HD, and 6500HD medium-duty trucks, effectively discontinuing the Silverado MD line as part of ending its manufacturing agreement with International Trucks. Production is scheduled to stop by September 30, 2026 at the Springfield, Ohio plant, with the related International CV Series production ending earlier in September 2026.
Details and context
- What’s ending: The Silverado HD “MD” lineup (the medium-duty 4500HD, 5500HD, and 6500HD) is being discontinued, along with certain Express and Savana cutaway variants, as GM declines to renew its long-running production agreement with International Trucks. This marks GM’s withdrawal from the Class 6 and 7 commercial truck segment in North America.
- Timeline: Production at International’s Springfield, Ohio facility will end on September 30, 2026 for GM’s Silverado MD models; the end of International’s CV Series and related lines is pegged to earlier in September 2026. GM has indicated it will not renew the agreement, and is evaluating future medium-duty portfolio options.
- Plant implications: The Springfield plant has been central to both the Silverado MD and International CV Series production; its role is changing as the agreement ends and ownership/operations shift. This transition has already influenced production planning and supplier dynamics in the medium-duty segment.
- Market rationale: GM cited softening demand in the heavy-duty segment and a strategic shift toward electric vehicles and more efficient platforms as part of the rationale for exiting this portion of the lineup. Several outlets note a sales downturn in the largest Silverado models contributing to the decision.
What this means for you
- If you were looking for new Silverado MD medium-duty trucks (4500HD/5500HD/6500HD) or related Express/Savana cutaways, GM will no longer offer them after September 2026, and dealers will transition to other GM products or commercial offerings. Availability of new units will wind down as the end-date approaches.
- For fleet planning, expect shifts in procurement toward lighter-duty alternatives or alternative commercial platforms, and potential opportunities for used inventory in late-2026 as the market adjusts.
