Designed as straight trucks for local construction, waste removal, and other vocational jobs, it is also available as a semi-tractor.

Mack builds their own major components (engines, transmissions, axles, and suspensions) and the Granite has specific packages for different applications.

It is a 659 cubic inches (10.8 L) overhead cam turbocharged inline six-cylinder diesel engine.

[7] The Cummins Westport L9N is a 543 cubic inches (8.9 L) turbocharged inline six-cylinder natural gas engine.

Manual transmissions have five or six main gears, extra ratios are made with different combinations of ranges.

The RDS is a fully automatic planetary gear transmission with a lock-up torque converter.

A set forward axle, with the tires immediately behind a straight bumper, is used when overall length is limited or when wheelbase has to be as long as possible for bridge-formula laws.

A very light feel and automatic return-to-center feature are useful off-road, at slow speed, and in backing.

With the higher level above the ground the driveshafts and u-joints are less prone to dirt and damage, important in on/off road construction.

[12] The Twin Y air suspension has trailing arms that fork to the rear and attach to both the top and bottom of the axle.

They can have leaf springs, rubber load cushions, air bags, or be solidly mounted.

Vendor tandems from Chalmers, Hendrickson, Meritor, and RAYCO are rated at up to 46,000 pounds (21,000 kg).

Mack has standard packages for dump, concrete mixer, roll-off(hooklift), and rear loader bodies, as well as semi-tractor.

The Granite, with its extra heavy-duty chassis, high ground clearance, and high-visibility cab, was designed to be operated on construction" job sites".

They commonly haul construction debris but refuse containers are also left at commercial sites.

Typically a rear crew can load loose material, bins with assist, oversize pieces, and small containers.

The first snowplow model became available mid-2003 and featured a heated windshield and mirrors (and Mack's "Visibility" doors with peep windows), while the air cleaner was placed inside the hood to protect it from ice and snow.

The plow/hitch carrier formed an extension of the front frame rails and was constructed from high-strength steel.

[15] While the Granite has high ground clearances as standard, Mack offers an increased frame height option since the introduction of the axle-forward snowplow version in March 2018, providing even more clearance for under-truck blades.

[16] Reinforced front frame rail extensions are also available; additional cold-weather options include heated side windows, mirrors, and various mechanical components.

Vocational, utility, heavy delivery, any application that needs a strong chassis.
