We have full information about the redesigned 2011 Chevrolet Silverado HD. Photos and details inside.

Chevy introduced the facelifted 2011 Chevrolet Silverado Heavy-Duty at the Chicago Auto Show this week.  The truck's new exterior features include a sleeker front chrome bumper, power dome-style hood, and new grille.

According to statements from the automaker, the engineering and design teams focused on 11 different points to improve the vehicle.  Changes include rebuilt frames that are now stiffer than they had been.  The new frames support as much as 16,000 lbs, with the new front suspension supporting as much as 6,000 lbs on the front axle.  Remodeled, wider leaf-spring rear suspension can take another 6,200 to 7,050 pounds with single wheel configuration, or a much stronger 9,375 pounds with dual rear-wheels, a 14% improvement.  The truck is capable of towing 16k lbs on a ball hitch, or 20,000 lbs with a fifth-wheel.

Also retuned is the diesel 6.6-liter Duramax engine estimated to be stronger and more powerful with reduced emissions.  The result is a 0-60mph time of under nine seconds.  Larger brakes, exhaust braking, and an improved ride round out the package along with more safety features and a more comfortable cab.

The 2011 Chevrolet Silverado 2500HD and 3500HD will hit the market this summer.  You can read more about the vehicle in the press release below.
