The core capability of Atlantic Detroit Diesel-Allison (ADDA) is the sale and expert service of diesel and alternative-fuel engines, transmissions, power-generation systems, and a wide range of related products, components, parts and accessories.

It is this range of solutions that keep our customers’ vehicles and other critical equipment running at maximum efficiency.

ADDA also provides comprehensive service for a variety of equipment in both on- and off-highway markets: medium- and heavy-duty trucks, buses and coaches; fire and emergency vehicles; power-generation systems; marine propulsion and support equipment for both commercial vessels and pleasure craft; and construction and industrial machinery.

The world depends on the equipment that depends on us.

With five locations throughout New Jersey, New York, Massachusetts and Connecticut, ADDA serves customers in some of the most demanding applications in both government and private-industry sectors. You’ll find our products hard at work in trucks, buses, ferry and commercial-marine applications, and pleasure craft, as well as in governmental, financial, and medical environments where ongoing power supply is critical.
