Most everyone loves the sight of a Winter Wonderland, but all that can change behind the wheel, since driving under wintry conditions can cause more of a headache than anything else. That's where snow plow trucks come into play, with the GMC Sierra HD full-size pickup leading the way.
According to GMC, not all plow-equipped trucks are created equal. The GMC Sierra truck has an edge over other plow-equipped trucks, thanks to a comprehensive plow prep package with an adjustable torsion bar front suspension as one of the most important components.
"Our competitors' beam axles can't match it for traction on uneven surfaces and axle hop reduction," said Sierra ride and handling engineer Chris Bither in a press release.
Engineers paid close attention to the front axle loads when designing the Sierra HD trucks, making the torsion bars easily adjustable with a single wrench to provide the proper wheel alignment when a plow is added. A plow can drastically affect wheel alignment, since equipment can weigh as much as 1000 pounds. For strong traction and support for heavy loads like road salt, engineers also added three-inch-wide asymmetric leaf springs to the Sierra's rear suspension.
All four-wheel drive Sierra trucks are available with the plow prep package, which comes complete with a 10-amp power for back-up and roof emergency lights, heavy-duty 160-amp alternator, heavy-duty front bumper, forward wiring harness, trailer brake wiring harness, skid plate, high-flow air cleaner, and auxiliary transmission oil cooler. All this is covered under GMC warranty.
