The 2021 Silverado 3500HD is assembled at the GM Flint plant in Michigan.
Additionally, the Oshawa plant in Canada is currently only building Chevrolet Silverados. Production began with the Silverado HD in November. In the spring of 2022, Oshawa will begin producing Silverado 1500s, timed with the launch of the refreshed model announced earlier this year. This will make Oshawa the only GM plant to exclusively produce Silverado models, and the only plant making both light and heavy-duty trucks.
2021 Silverado 3500HD units reached dealer lots by the end of the third quarter of 2020.
We expect the fourth-generation Silverado HD to remain in production thru the 2026 model year.
An all-new, next-generation Chevy Silverado will most likely launch after the 2026 model year.
