Founded by two brothers in a Brooklyn, New York workshop, Mack Trucks is now one of the major trucking OEMs in the world.

“Mack is honored to receive this prestigious Milestone Award from the Lehigh Valley Chamber of Commerce,” said Stephen Roy, president of Mack Trucks. “We assemble all of our Class 8 models right here in the Lehigh Valley, and we appreciate the hard work and commitment of the Chamber, the community and our employees, without whom we wouldn’t have been able to achieve this milestone.”

All Class 8 Mack trucks for North America are assembled at Lehigh Valley Operations (LVO) in Macungie, Pennsylvania. Mack Class 6 and 7 models are assembled at Roanoke Valley Operations (RVO) in Salem, Virginia.
