New Truck Modification Center

The TransEdge Modification Center brings you 25 years of experience in heavy duty truck service. All mechanics at our facility are Mack factory trained/certified and have an average of 16 years experience in the industry. Our eight-bay, 7,500-square-foot facility, is located on Tilghman Street in Allentown. Our close location to the Macungie Plant Branch allows us to pass savings to you through the Mack/Factory Freight Equalization Program.

We stock over $4.1 million in parts in our on-site, fully staffed warehouse and work with fleets, individual truck owners, and Domestic & International Mack Distrubutors.
