The 2010 Chevrolet Silverado heavy-duty models are ready for any task, whether work or leisure. They are offered in a range of 2500HD (three-quarter-ton) and 3500HD (one-ton) models; and are available in WT, LT and LTZ trim. A wide range of configurations -- three cab styles, three cargo box styles and five wheelbase lengths -- delivers tremendous choice.

The Silverado HD pickups also offer many segment-best capabilities, including 18,500-pound Gross Combined Vehicle Weight Rating for vehicles with a gas V-8 and a 13,000-pound conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 16,700 pounds when equipped with a fifth-wheel hitch.

Changes for 2010 are minor and include a pair of new exterior colors and the inclusion of a USB port on all but the base radio.

Silverado heavy-duty models have bold, muscular designs that are differentiated from their light-duty siblings. This includes specific grilles, headlamps, hoods and front fenders -- all conveying broad-shouldered, ready-for-anything strength.

The standard engine is a 6.0L gas V-8 with variable valve timing. It is rated at 360 horsepower and 380 lb.-ft. of torque. A Hydra-Matic 6L90 six-speed automatic transmission is paired with the 6.0L engine.

A clean and powerful Duramax 6.6L turbo-diesel engine is available. It has power ratings of 365 horsepower and 660 lb.-ft. of torque. The renowned Allison 1000 six-speed automatic transmission is partnered with the Duramax 6.6L turbo-diesel engine.
