Stellantis’s Saltillo complex in Coahuila, Mexico, also builds heavy-duty Ram trucks at a separate, older plant. The light-duty plant began assembling the Ram 1500 in February 2026, according to Mexico Business News, with the first truck a Ram 1500 Bighorn Crew Cab 4x4 for the Mexican market.
Ram’s 2027 Ram 1500 press kit lists the Saltillo Light-Duty Truck Assembly Plant next to Sterling Heights as a manufacturing site for the pickup.
