RAM trucks are built by Stellantis, a multinational automaker formed in 2021

RAM is a truck brand owned and manufactured by Stellantis, a company created when Fiat Chrysler Automobiles and the PSA Group merged in January 2021. Before that merger, RAM was built by Chrysler, which had owned the brand since 2009. Stellantis is now one of the world's largest automakers by revenue, and RAM remains one of its most profitable divisions.

RAM trucks are not built in a single location. Different models and generations come from different factories across North America, and Stellantis has shifted production between plants over the years. Understanding where your truck was built matters if you need parts, warranty service, or want to know about the factory conditions and labor practices behind your vehicle.

Key Takeaways

  • Stellantis owns and manufactures RAM trucks following the 2021 merger of Fiat Chrysler Automobiles and PSA Group.
  • RAM 1500 pickups are primarily built at the Sterling Heights Assembly Plant in Michigan and the Silao plant in Mexico.
  • Heavy-duty RAM 2500 and 3500 trucks are manufactured at the Dodge City Assembly Plant in Kansas.
  • RAM also builds commercial vans and chassis at facilities in Indiana and Ohio.
  • You can find your truck's factory location on the door jamb label or in your owner's manual under "vehicle information."

Where RAM 1500 pickups are manufactured

The RAM 1500, which is RAM's most popular model, is built at two main locations. The Sterling Heights Assembly Plant in Sterling Heights, Michigan produces the majority of RAM 1500s sold in North America. This facility has been a Chrysler and RAM production center for decades and employs thousands of workers.

Stellantis also manufactures RAM 1500 trucks at the Silao Assembly Plant in Guanajuato, Mexico. This facility opened in 2016 and handles a significant portion of RAM 1500 production, particularly models destined for the Mexican market and some exported to the United States. The split between these two plants means that two RAM 1500s on a dealer lot may have come from different countries.

Heavy-duty RAM 2500 and 3500 production

RAM's heavy-duty trucks—the 2500 and 3500 models—are built exclusively at the Dodge City Assembly Plant in Dodge City, Kansas. This facility specializes in larger, more complex trucks and has been producing heavy-duty pickups for Chrysler and RAM for many years. If you own a RAM 2500 or 3500, it came from Kansas.

The Dodge City plant is also where RAM builds chassis cabs and other commercial variants of its heavy-duty line. These vehicles are often sold to upfitters who add specialized equipment like dump beds, flatbeds, or service bodies for commercial use.

RAM commercial vans and other vehicles

RAM manufactures its commercial van line—the ProMaster and ProMaster City—at different facilities depending on the model. The full-size ProMaster is built in Turkey at a Stellantis facility, while some van production also occurs in other international plants. The ProMaster City, a smaller commercial van, is produced in Morocco.

RAM also builds the Chassis Cab (used for motorhomes and commercial conversions) at the Saltillo Assembly Plant in Coahuila, Mexico, alongside heavy-duty truck production. Stellantis operates multiple manufacturing sites across North America and Europe, and RAM production is distributed among several of them based on model type and market demand.

How to find where your specific truck was built

Every vehicle has a door jamb label on the driver's side door frame that shows the factory where it was assembled. Open your driver's door and look at the inside edge of the door frame—you'll see a sticker with vehicle information including the plant code. The label typically shows a two-letter or three-letter code that identifies the assembly plant.

You can also check your owner's manual, which usually includes a section on "vehicle information" or "specifications" that explains the plant codes. If you're buying a used RAM truck and want to know its origin before purchase, ask the dealer or seller to show you the door jamb label. Online resources maintained by RAM and Stellantis can help you decode the specific plant code on your vehicle.

Why manufacturing location matters

Knowing where your truck was built can affect warranty coverage, parts availability, and service. Some dealers may have closer relationships with certain plants or may stock parts more readily for vehicles built at nearby facilities. If you need a recall repair or have a warranty claim, the plant code helps service centers understand your truck's specific configuration and any plant-specific issues.

Manufacturing location also reflects labor practices and quality standards. Stellantis facilities in the United States operate under United Auto Workers (UAW) agreements, while Mexican and international plants operate under different labor frameworks. Some buyers prefer vehicles built in specific countries for economic or ethical reasons, and the door jamb label gives you that information.

Changes to RAM production over time

RAM's manufacturing footprint has shifted as Stellantis restructures operations and responds to market demand. The 2019 redesign of the RAM 1500 led to production changes, with the Sterling Heights plant taking on more of the workload. Stellantis has also announced investments in electric vehicle production, which may eventually change where RAM builds its trucks as it introduces battery-electric models.

If you own an older RAM truck, it may have been built at a facility that no longer produces RAM vehicles. Chrysler's Warren Truck Assembly Plant in Michigan, for example, previously built RAM 1500s but has since been retooled for other production. This is why checking your specific vehicle's door jamb label is more reliable than assuming all RAM trucks come from one location.

Frequently Asked Questions

Are all RAM trucks made in the United States?

No. While RAM 1500s and heavy-duty trucks have significant U.S. production at Sterling Heights, Michigan and Dodge City, Kansas, RAM also manufactures trucks at facilities in Mexico and other countries. The Silao plant in Mexico produces a large portion of RAM 1500s, and commercial vans are built internationally.

Is a RAM truck built in Mexico as good as one built in Michigan?

Quality standards are set by Stellantis corporate policy and explore across all facilities. However, individual plant performance can vary. Your truck's specific quality depends more on its individual assembly and maintenance history than on which country it was built in. Check your door jamb label and research that specific plant's reputation if quality is a concern.

Can I find out where a used RAM truck was built before I buy it?

Yes. Ask the dealer or seller to show you the door jamb label on the driver's side door frame, which displays the plant code. You can also request a vehicle history report, though these don't always include plant information. The label is the most direct way to confirm the factory.

Does the manufacturing plant affect warranty coverage?

No. RAM's warranty is the same regardless of where the truck was built. However, the plant code helps service centers understand your truck's configuration and any plant-specific recalls or known issues. All RAM dealers can service any RAM truck regardless of its origin.

Will RAM move all production to Mexico or other countries?

Stellantis has not announced plans to move all RAM production out of the United States. The company continues to invest in U.S. facilities, though production volumes and model assignments can shift. Future electric RAM trucks may be built at different facilities as Stellantis builds out its EV manufacturing capacity.
