We’re Now Carrying Mack Parts!

It was the year 1900. In the heart of Brooklyn, New York, the Mack legacy began with a bus built by three enterprising brothers: John “Jack” Mack, Augustus Mack, and William Mack. Their story actually started a few years earlier, in 1893, when Jack and Augustus bought the wagon company Jack worked for. Inspired by great American inventors like the Wright Brothers, Willis Carrier, and Henry Ford, the Mack brothers saw the potential in moving beyond wagons and steam power to something greater—heavy-duty, reliable, motor-powered vehicles.

By 1900, they were in full swing as the Mack Brothers Company, opening their first bus manufacturing plant. Their first truck rolled out in 1907, and their momentum never slowed. What followed was a series of groundbreaking contributions to the trucking world that helped shape the modern trucking industry as we know it.

Mack was responsible for several firsts:

• The first to apply air cleaners and oil filters in 1918.

• The first truck with power brakes in 1920.

• The first manufacturer to produce its own diesel engine in 1938.

• And in the 1960s, they introduced the Maxidyne engine, which changed the game for heavy-duty trucks by reducing the need for complex transmissions.

During World War I, Mack delivered over 6,000 trucks to American and British forces. Their ruggedness impressed British soldiers so much that they gave them the venerable nickname of “Bulldogs.” The nickname stuck and became a core part of the brand’s identity. By 1922, the company officially became Mack Trucks, and the bulldog emblem was born—first as a steel plate, and later as the iconic hood ornament. Today, a gold-plated bulldog signifies a truck made entirely from Mack parts, while a chrome bulldog indicates a combination of Mack and other manufacturers’ components.

Mack’s commitment to innovation, durability, and power has made them a staple on American roads and job sites. From construction and refuse management to heavy-haul, logging, and municipal services, Mack trucks are known for thriving under pressure. They're not just dominant in Class 8 long-haul operations—they’ve also expanded into medium-duty trucks with the Mack MD Series, introduced in 2020, and its electric successor, the MD Electric.

Their advanced Mack Connect technology brings data-driven efficiency to fleets, providing real-time insights on everything from fuel economy to preventive maintenance. This connectivity keeps drivers and businesses one step ahead in a fast-moving logistics world.

With trucks sold in 45 countries and their primary manufacturing plant in Pennsylvania, Mack continues to be a top-tier manufacturer of both on-road and off-road commercial trucks and parts. Their reputation for building vehicles that last is not just historical—it's happening every day.

For over 125 years, Mack Trucks has stood for strength, reliability, and American ingenuity. They’ve survived wars, economic shifts, and evolving industry standards—and they’ve done it all while staying true to their roots. Because what else is “Built Like a Mack Truck?”
