Mack’s legacy of application excellence brings smarter integration for vocational jobs

The Mack® Granite® model has long been a cornerstone of job sites where reliability and toughness aren’t optional. With the introduction of the all-new Granite, Mack is doubling down on the features vocational operators value most, starting with truck configuration, body builder integration, and the flexibility required to excel across industries.

“The next-generation Granite is more configurable, more adaptable, and easier than ever to integrate with vocational bodies,” says Alex Lee, senior product manager, vocational and medium duty trucks, Mack Trucks. “It’s a focused evolution driven by the needs of fleets, body builders, and operators who rely on precision, productivity, and uptime.”

At the heart of the all-new model remains Mack’s unwavering commitment to application excellence: the ability to configure the truck precisely for the work it will perform, and to streamline body integration so builders can deliver specialized solutions faster and with higher levels of control. This pairing of versatility and integration is what has defined the Granite’s reputation in vocational industries, and it’s not a legacy to be reimagined, but one to be enhanced in this latest edition.

Purpose-built configurations

“While some vocational trucks lead with power and hope versatility follows, the Granite starts from a different place: the job site,” says Lee. “The all-new Granite remains purpose built for mixers, dumps, roll-offs, refuse bodies, and a wide range of municipal and construction duties, and expands the configuration possibilities in several practical ways.”

The latest Granite features an all-new galvanized steel cab, that’s more spacious than the outgoing cab, with 9 inches of additional width at the driver’s shoulders. The bumper-to-back-of-cab (BBC) has been reduced to 113.5-inches to enhance maneuverability and support greater flexibility for body upfitting. Front axle-forward and axle-back options also continue, allowing operators to tailor maneuverability, bridge law compliance, or weight distribution to regional preferences.

For Granite customers who operate in multiple states or in industries where legal axle spacing determines profitability, that flexibility remains essential. While the Granite has carved a reputation as a premium vocational day-cab, the new cab is also available with an optional 44-inch mid-roof sleeper, providing operators with the flexibility to run extended routes or overnights.

Body Builder Integration

From evolutionary to the revolutionary, Mack is raising the bar for body builder integration with the all-new Granite, enabling builders to connect, communicate, and command equipment with greater precision. Introduced with the all-new Granite, the new Mack BodyLink IV with Parameter Configuration Tool (PCT) is the most advanced chassis-to-body electrical integration system Mack’s ever built. The innovative system is engineered to give body builders, fleets, and operators complete control over how their trucks work to maximize productivity, safety, and profitability. This latest edition of Mack’s industry-leading electrical connection system is essentially a toolkit for upfitters to build custom trucks, offering the necessary data and connections for seamless body installation, especially for vocational applications.

BodyLink IV with PCT can be tailored to specific needs of each body builder, allowing them to program flexible switches, interlocks, and logic functions on the truck without requiring additional harnesses, add-on controllers, or aftermarket workarounds. For mixers, dumps, hook lifts, refuse, and municipal bodies, where hydraulic sequencing, operational safety systems, and lockout controls are critical, the PCT is a transformative addition. Complex bodies can be configured more cleanly and with standardized logic, simplifying troubleshooting, documentation, and service. Extensive and customizable pre-wiring, connections, flexible switches, screens, and configurable tools help body builders shorten installation times, improve quality, enable safety features, and reduce costs.

“In practice, it also shortens the build cycle,” says Lee. “With the PCT, builders spend less time modifying wiring and programming controls, and fleets receive more consistent systems across trucks, even when upfits vary by job type or body manufacturer. The new Granite isn’t just compatible with bodies; it’s engineered to be integrated with them.”

Supporting the platform are Mack’s dedicated application engineers and body integration specialists, who collaborate directly with body companies during the build process. That layer of human expertise reinforces Granite’s long-standing legacy of application excellence, built around partnership, not just hardware.

“Modernization is about adding capability, never trading one for another,” says Lee. “The Granite is built for severe terrain, unpredictable environments, and work that often happens where roads technically don’t exist. That identity remains intact as the Granite platform moves into a new technological era.”

Application Excellence, Reinforced

Granite reflects Mack’s long-standing commitment to application excellence: configure the truck correctly, integrate the body cleanly, and support the customer throughout the build and beyond.

Mack didn’t just reinvent a vocational icon; it sharpened it. Each new Granite is integrated from the start and purpose-built around the application to dominate the jobsite.

▪ For body builders, it means a smarter, more efficient interface.

▪ For operators and fleets, it's confidence that every truck is built for its exact role.

▪ For the Granite, it’s a continuation of a legacy defined by purpose-built capability and dependable performance.
