The new HD models are also "power players" when it comes to trailering, White said. With the factory-installed weight-distributing hitch, the trailer weight rating can reach up to 12,000 pounds, when properly equipped. With a fifth-wheel or gooseneck-style hitch, that capacity nears 16,000 pounds.
A Gross Combination Vehicle Weight Rating (GCWR) of 22,000 pounds puts Silverado HD and Sierra HD at the head of their class, White noted, while Gross Vehicle Weight (GVW) numbers are 9,200 pounds for the 2500HD models and up to 12,000 pounds for the 3500 Series.
"Of course, with strong numbers like these," White said, "the frames must be up to the task." So the frame structures on all the new HD models are modular in design and feature GM's hydroformed process for the front section, to offer extra rigidity.
White added that, "In fact, the 1-ton chassis-cab frame, featuring straight frame rails, meets all the requirements of the National Truck Equipment Association for body/equipment installation."
These new Silverado HD and Sierra HD models will be available in regular cab, 4-door extended cab, Crew Cab and chassis-cab models.
They will also have a slightly different exterior look than the regular Silverado and Sierra models.
The Silverado HD's look includes a distinctive heavy-duty front end that features a bigger gold bowtie set against its heavy-gage chrome grille. The Sierra's new look is also exclusive to its 2500 HD and 3500 models and, like the Silverado, White said, and stands taller than ever.
