AERODYNAMIC DESIGN
The Mack® Bulldog® sits low on Granite's sloped hood providing improved aerodynamics on the road and excellent visibility on the jobsite. And the larger radiator opening provides better cooling with less fan engagement.
DURABLE HEADLIGHTS
The LEXAN® headlight covers are impact resistant to handle the punishment of rocky jobsites and offer easy accessibility for replacing bulbs without a single tool.
THREE-PIECE BUMPER
Granite™ has a three-piece stylized front bumper that makes replacement easy and economical.
SPLASH SHIELDS
Hood splash shields keep the compartment clean extending component life, and they lift with the hood to create more room for technicians to work.
DURABLE HOOD
Hood isolators allow the hood to flex independently for increased durability over rough terrain.
GALVANIZED STEEL CAB
Granite's durable galvanized steel cab is mounted on airbags and shocks and stabilized with sway bars, so while the truck soaks up the rough stuff, the driver stays comfortable, rested and productive.
RUBBER-SEALED WINDSHIELD
A two-piece windshield is isolated in a rubber seal, which puts less stress on the windshield and makes it easier to replace.
COLLAPSIBLE MIRRORS
Collapsible mirrors fold in to eliminate door sheet metal damage in tight jobsite conditions. Heated, lighted and motorized mirrors are available.
EASY CAB ENTRY
Sculpted, self-cleaning steps and a full-size grab bar provide an extra measure of safety getting in and out of the cab.

CAB MOUNTED EXHAUST
The exhaust is flush with the back of cab to provide 10 inches more room for body builders as compared to a stanchion-mounted exhaust.
UNDER CAB MOUNTED COMPONENTS
The LEXAN® headlight covers are impact resistant to handle the punishment of rocky jobsites and offer easy accessibility for replacing bulbs without a single tool.
"D" SHAPED FUEL TANK
Granite is available with this unique tank design that holds more fuel in the same space.
CAB AIR SPRINGS
Drivers can work more comfortably thanks to large, outboard-mounted air springs that provide cushioning, stability and reduced vibration.
HOOD SAFETY LATCH
The hood safety latch engages automatically and keeps the hood up, even in the windiest conditions. Disengage the latch by simply flipping it up before closing the hood.
LARGE PEEP WINDOW
The large peep window and visibility door provide exceptional views, and the quick release mechanism allows easy access for cleaning.
SUN VISOR
Stainless steel or painted sun visors are available.
FRONT FENDERS
Flexible hood-mounted fender extensions are positioned to protect the hood and control road splash.
AIR INTAKES
Granite features optional bright finish air intake vents.
