GM has not publicly confirmed a permanent end to Silverado HD production with reports indicate the Silverado 4500HD, 5500HD, and 6500HD are being discontinued due to a non-renewed contract with International Trucks production is set to end by September 30, 2026. The move reportedly affects Springfield, Ohio lines driven by soft demand for diesel-powered commercial vehicles, but consumer Silverado pickups (1500/2500/3500) remain unaffected. Some reports indicate broader Express/Savana Cutaway variants may be impacted, GM has not provided replacements for the medium-duty lineup.
