Chevrolet Silverado introduced all-new heavy-duty pickups during the '07 model year. They were highlighted by all-new and differentiated exterior designs, two unique interiors and class-leading power and efficiency. They roll into 2008 ready for work or leisure, with minor refinements and enhancements, while still loaded with include segment-leading and segment-exclusive features.
Silverado heavy-duties are offered in a range of 2500HD (three-quarter-ton) and 3500HD (one-ton) models; and are available in WT, LT and LTZ trim. The range of configurations - three cab styles, three cargo box styles and five wheelbase lengths - delivers tremendous choice. Some full-size truck manufacturers do not even offer three-quarter-ton or one-ton heavy-duty trucks. And among those that do, the 2008 Silverado HD pickups offer many segment-best capabilities, including 18,500-pound (8,392 kg) gross combined vehicle weight rating for vehicles with a gas V-8 and a 13,000-pound (5,897 kg) conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 16,700 pounds (7,575 kg), when equipped with a fifth-wheel hitch.
Changes to the Silverado 2500HD and 3500HD for '08 are minor, and include standard XM Satellite Radio on all models, availability of a power-adjustable driver's seat on regular cab models with a bench seat, brighter instrument pointers in the gauge cluster and two new exterior colors: Dark Cherry Metallic and Deep Ruby Metallic.
Dually models in 2008 receive new, larger 17-inch wheels (replacing 16-inch wheels), which are available with bright wheel covers. Also, the 6.6L Duramax diesel engine is capable of running on B20 biodiesel.
