Mack Lehigh Valley Operations


Every Mack truck built for the North American market gets its start at the company’s cab and vehicle assembly plant in Macungie, Pa.

Located just outside of Allentown, the 1.7 million square-foot plant has three cab and two chassis assembly lines, a truck modification center, engine groom line and much more.

In recent years, the Macungie plant has become a model for environmental management in heavy-truck manufacturing. Energy use and carbon dioxide emissions have both been reduced by around 50 percent from 2009 levels. In 2013, Mack became the first U.S. manufacturer to achieve SEP Superior Energy Performance) Platinum Mature Energy Pathway certification.
