The Mack Granite® MHD gives you durability without the extra weight. Ideally configured for shorter runs and lighter-duty cycles, Granite MHD reduces weight without sacrificing durability and comes in Class 7 and Class 8 configurations.
The Granite MHD is available in 6×4 and 4×2 configurations and is prepared to take on your daily challenges. It comes in axle forward and axle back models, and starts at a 33,000-lb. GVW rating. Its cab-mounted exhaust provides a clean back-of-cab to accommodate almost any body option.
With a tight steering radius, Granite MHD is perfect for narrow streets and crowded jobsites. Granite MHD has the right power for when you don't have to haul a heavy load, but need plenty of strength for the toughest jobs.
The unyielding foundation of any job, Granite MHD has the brawn to get the job done right. Heavy-duty crossmembers provide the strength to tackle any job, while a rugged galvanized steel cab and rubber-sealed windshield keep drivers safe. Top-mounted rear axle carriers minimize driveline angle and improve fuel efficiency and ground clearance.
The Granite MHD gives you a rock-solid performance every time you drive. It comes equipped with a Cummins ISL9 345 HP engine, offering a maximum torque rating of 1,150 lb.-ft.
To fit the needs of whatever job you face, the Granite MHD offers either an Eaton-Fuller manual or an Allison automatic transmission.
Keep moving forward with the Granite MHD’s uniquely designed tank that allows you to hold more fuel in the same space, with 66-, 88- and 110-gallon capacities available. A 6.6-gallon integrated DEF tank is standard.
The Cornerstone chassis utilizes a high-strength steel alloy design and constant rail height to create a strong-yet-light frame to handle whatever the workday throws at you. This chassis has a 7-mm frame rail thickness specifically for the Granite MHD and is also available in 8-, 9.5- and 11.1-mm frame rail thicknesses.
With UniMax axles, you move the way you want. The short distance from bumper to tire provides front-end swing clearance, outstanding wheel cuts and an exceptional turning radius. And its steer axle hubs are sealed and maintenance-free. The Granite MHD’s ideal axle option is the 16,000-lb. axle capacity, but four additional axle options are available in 12,000-, 14,600-, 18,000- and 20,000-lb. capacity.
The Granite MHD’s durable, galvanized steel cab is mounted on airbags and shocks, so you stay comfortable while your truck does all of the heavy lifting.
The Mack Granite MHD’s redesigned interior is designed to be a sanctuary on rough roads while keep drivers safe, comfortable and productive. Redesigned and purpose-built, Granite MHD’s interiors minimize driver wear and tear and maximize comfort. With additional storage, Mack-exclusive seats, steering wheel controls and a customizable dash with four optional auxiliary guages, the Mack Granite MHD's interior gives you comfort and control to help you have the best possible driving experience.
