Mack Defense has moved from its leased office space in Upper Macungie Township to the Mack Customer Center in Allentown.

The Mack Trucks plant in Lower Macungie Township was among facilities honored by the U.S. Department of Energy for reducing waste.

Before NASCAR’s race cars hit the track, they need to be hauled there, and, thanks to a new partnership agreement, Lehigh Valley-made Mack Trucks will continue to do the job.
