Chevrolet has unwrapped the Silverado HD line-up for model year 2011 at the Chicago Auto Show. Boasting the best-in-class payload capability, the new Silverado heavy-duty truck is available in 11 different 2500HD model variations and 8 single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box.

"We reached out to our customers during the development of the 2011 Silverado HD and considered their input to produce a truck that offers class-leading strength and capability with more power, quicker acceleration and lower emissions," said Jim Campbell, Chevrolet general manager.

The new Chevrolet Silverado HD boasts some serious refinements for 2011: all-new, fully-boxed frame assemblies, stronger independent and new asymmetrical leaf-spring rear suspensions, a strengthened 6.0L Vortec 6L90 standard power unit; a new, exclusive exhaust brake system, larger brakes, improved handling and steering, 170-degree-opening rear access doors on extended cab models and state-of-the art connectivity.
