L. MACUNGIE TWP., Pa. – It’s something old, and something new from the Bulldog in Sin City.
Mack Trucks is unveiling two additions to its vocational lineup this week at the ConExpo-Con/Agg 2026 construction trade show in Las Vegas. Both trucks will be assembled at the company’s plant in the Lehigh Valley.
Mack Trucks unveiled two all-new models at the Las Vegas Motor Speedway, ahead of ConExpo-Con/Agg 2026, March 3–7 at the Las Vegas Convention Center: the all-new reimagined and redesigned Mack Granite and the all-new Mack Keystone.

First, the new. The Mack Keystone takes its name from Pennsylvania’s nickname of the Keystone State.
“The Keystone continues Mack’s tradition of building rugged, reliable trucks that work as hard as the people who drive them,” said Stephen Roy, president of Mack Trucks, in a news release.
The Keystone can hack it on both highways and rougher terrain, according to Fernando Couceiro, Mack Trucks vice president of highway trucks: “Whether you’re hauling logs out of a forest, delivering heavy equipment to a construction site or transporting agricultural goods across rural roads, the Keystone is built to handle it all.”
The truck will be sold in North American markets, as well as select international markets, marking the first time Mack has offered this class of vocational tractor in Latin America.
Now, the old: although, technically, the Mack Granite could be considered newish. It’s a “reimagining” of a model Mack has produced for 25 years.
The new Granite features an all-new galvanized steel cab that is larger than its predecessor, in addition to what the company calls cutting-edge safety technologies, including E911 auto-call, which automatically contacts emergency services if an airbag deploys or the system detects a rollover or collision.
“The all-new Mack Granite embodies everything Mack stands for: legendary durability, uncompromising performance and a commitment to our customers who depend on these trucks to get the toughest jobs done,” said Roy. “We’ve completely reimagined the Granite from the ground up, bringing the same level of innovation we delivered with our Pioneer and Anthem models to the vocational market.”
The Pioneer and Anthem are long-haul trucks introduced in 2025 (an older version of the Anthem was first introduced in 2017). They’re also assembled at Mack’s Lower Macungie Township plant, referred to as Lehigh Valley Operations, or LVO, where all Class 8 models for North America and export are put together.
Both the Mack Keystone and Granite will be available to order later this year.
