Penn Power Group, formerly Penn Detroit Diesel Allison, has evolved into a company that provides a vast array of world class products and services to an expanded base of customers.
Our rich history began over fifty years ago with Engines Incorporated which began our relationship with Detroit Diesel and Allison Transmission products in the eastern Pennsylvania region. In 1977, Engines Inc. was sold and renamed Penske Detroit Diesel Allison and in 1983, a management buyout took place and the company was renamed Penn Detroit Diesel Allison.
Penn Power Group is proud to be affiliated with some of the world’s largest manufacturer’s and providers of clean and efficient diesel and multi-gas engines, transmissions, transport refrigeration products, hybrid products and power generating equipment. As our customers transition through technology advancements within our industries, they can be assured that Penn Power Group continues to evolve and provide superior solutions.
