Where are GMC trucks made?
GMC trucks are built primarily in North America at General Motors facilities in the United States and Mexico, with the Silverado and Sierra assembled at Fort Wayne, Indiana and Silao, Guanajuato, Mexico, and the mid-size Colorado and Canyon produced at Wentzville, Missouri. Production can shift by model year and market.
Primary locations for GMC full-size pickups (Silverado/Sierra)
These plants currently handle the bulk of full-size pickup production for GMC in North America, balancing capacity across regional markets.
- Fort Wayne Assembly, Indiana — builds the GMC Sierra and Chevrolet Silverado for North American markets.
- Silao Assembly, Guanajuato, Mexico — produces Silverado/Sierra variants for North American and export markets.
These facilities illustrate how GM distributes full-size truck production across the region to meet demand and optimize logistics.
Primary locations for GMC midsize pickups (Colorado/Canyon)
Mid-size pickups are produced at a dedicated GM plant to serve North American demand, with production concentrated at a single facility.
- Wentzville Assembly, Missouri — builds the GMC Canyon and Chevrolet Colorado.
Wentzville has long served as the home for GM's midsize pickups, reflecting the platform's lifecycle and regional demand.
Model-by-model production details
Full-size pickups: Silverado and Sierra
For the full-size trucks, Fort Wayne remains the core production hub for U.S. and Canadian markets, with Silao expanding capacity to support Mexico and export needs. GM has periodically adjusted shift patterns and production mix to align with demand, regulatory changes, and model updates. As of 2024–2025, these two plants form the backbone of GMC’s large-pickup output in North America.
Mid-size pickups: Colorado and Canyon
The GMC Canyon and its Chevrolet Colorado counterpart are produced at the Wentzville, Missouri site, where GM runs dedicated lines for midsize pickups. The plant’s configuration supports shared platforms with the GM midsize truck family, and production can be influenced by market demand, model-year updates, and regional supply considerations.
Summary
GMC trucks are manufactured mainly in North America across a few key GM plants: Fort Wayne, Indiana; Silao, Mexico; and Wentzville, Missouri. While Fort Wayne handles most full-size Silverado/Sierra output, Silao supports additional capacity for those models, and Wentzville serves as the primary site for Colorado/Canyon production. Plant assignments can shift over time with product updates and market needs, but these facilities remain central to GMC’s truck production as of 2024–2025.
