Currently, the company's primary manufacturing facilities are located at the Macungie Assembly Operations plant in Macungie, Pennsylvania, and at their New River Valley Assembly Operations in Dublin, Virginia. Mack Trucks is a top producer in the vocational, on-road-vehicle market, Class 8 through Class 13. It is also the most popular manufacturer of heavy-duty off-road trucks in America. The company's distinctive logo, a chrome-plated (sometimes gold-plated) bulldog, can be found on the front of almost all Mack trucks.

Mack trucks have been sold in 45 countries. The Macungie, Pennsylvania, manufacturing plant, located close to its Allentown headquarters, produces the Mack Granite, LE, and MR models, including the construction and refuse series products. In Dublin, Virginia, the Pinnacle and CH highway models are made at the New River Valley assembly plant. Engines, the Maxitorque ES T300 series transmissions, the TC-15 transfer cases, and rear engine power take-offs are designed and manufactured in Hagerstown, Maryland, which, according to local historians, was the original factory location.

Parts for Mack’s right-hand-drive vehicles are produced in Brisbane, Queensland, Australia, for worldwide distribution. Assembly for South America is done at Mack de Venezuela C.A., in Caracas, Venezuela. The Venezuela operation is a complete knock down (CKD) assembly facility. Components are shipped from the United States to Caracas, and the plant then does final assembly.

In addition to its Macungie manufacturing facility, Mack also has a re-manufacturing centre in Middletown, Pennsylvania where it takes used parts and refurbishes them for resale/reuse.

R/RB, U, RD, DM-ModelsEdit

Mack started to produce the R and U Model in the early 1960s, for highway use, and the RD and DM Models for construction use. The 4 models featured the same cab, the U and DM had the cab offset to the left, and the early RD and DM had 3-piece steel hoods. They later had 1-piece hoods, the RD had a new hood and the DM the U hood. In the late 1980s, the R and U Models were discontinued, the RB was introduced, mostly for severe-duty applications it is, and the hood was slightly modified.

2002 was the last year for the RD, and 2005 for the RB and DM, the DM being the last one to be discontinued, it was the last model to use this cab, and the last model of this family that was produced. As a replacement for the construction models, Mack started to offer the Granite, Granite Bridge-Formula and Granite Axle-back, however, they feature a centered cab, and which is not offset like the DM.

Maxidyne engineEdit

In the early 1960s, Mack Truck's executive vice president of product and engineering, Walter May, developed the Maxidyne high-torque rise engine. The engine was first available in the 1968 model year trucks. This was an industry-changing event. The Maxidyne allowed a heavy Class 8 truck to be operated with a 5 speed (Maxitorque) transmission. Previously, heavy trucks were typically equipped with 10 or more gears.

Other productsEdit

  • MP Engine Series


The company's trademark is the Bulldog. Mack trucks earned this nickname in 1917, during World War I, when the British government purchased the Mack AC model to supply its front lines with troops, food and equipment. British soldiers dubbed the truck the "Bulldog Mack", because they said it had "the tenacity of a bulldog." Its pugnacious, blunt-nosed hood, coupled with its incredible durability, reminded the soldiers of the tenacious qualities of their country's mascot, the British Bulldog.[13][14]

The logo was first used in 1921 for the AB chain drive models and made the official corporate logo in 1922.[15]
