The Silverado 3500 has long been one of the best heavy-duty pickups and still remains a favorite. Whether you're hauling or towing, this truck handles and rides well, especially for its size. GM's hydroformed frame design improves handling and is among the stiffest in the truck class. Large, heavy-duty disc brakes on all four wheels have reduced stopping distances and give the driver a solid pedal feel. Dynamic rear proportioning transfers front and rear brake bias to the tires with the best grip, improving braking performance and reducing wear on the brake pads. The Silverado's unique GM-designed transmission keeps in close contact with the engine, adjusting shift points according to driving style and keeping the gears in tune while towing. In addition, a Tow/Haul mode keeps the gears in sync with the engine and reduces brake use for better fuel economy.
