        	| AERODYNAMIC DESIGN The Mack Bulldog® sits low on Pinnacle's sloped hood providing improved aerodynamics on the road and excellent visibility. And the larger radiator opening provides better cooling with less fan engagement. DURABLE HEADLIGHTS The LEXAN® headlight covers are impact resistant and offer easy access for replacing bulbs without a single tool. VERSATILE BUMPER The durable bumper is designed with dual tow clevises, and is also equipped with fog lights for better visibility in inclement weather. SPLASH SHIELDS Hood splash shields keep the engine compartment clean extending component life, and they lift with the hood to create more room for vehicle maintenance and service. DURABLE HOOD Hood isolators allow the hood to flex independently from the cab for increased durability over rough terrain. GALVANIZED STEEL CAB Pinnacle'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 at less cost. COLLAPSIBLE MIRRORS Collapsible mirrors fold 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 externally-mounted grab bar provide an extra measure of safety getting in and out of the cab. UNDER CAB MOUNTED COMPONENTS The air tanks and battery box are neatly mounted under the cab, and a full selection of aluminum or steel fuel tanks are available to fit your needs. When Pinnacle™ is outfitted with fuel-tank fairings, all components are not only protected, but the side fairings work with the bumper to keep air flowing smoothly along the length of the tractor to boost fuel economy. "D" SHAPED FUEL TANK Pinnacle 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. AIR INTAKES Pinnacle features optional bright finish air intake vents. |
