Chevrolet Silverado 3500 HD Extended Cab
Select a Year
(2 available)
A bi-fuel system is available on 2500 HD models with the 6.0-liter engine and extended cab. With it, the truck can run on regular gasoline or compressed natural gas (CNG). Also, the Duramax 6.6-liter V8 diesel engine is now available on 3500 HD chassis cab models.
The 2012 Chevrolet Silverado HD trucks make new strides for 2012, with Chevy claiming best-in-class accolades for maximum fifth-wheel towing, conventional towing and payload.
Building on the well-received Tahoe, Suburban and lighter-duty 1500 pickups, Chevrolet's Heavy Duty series brings increased capabilities, refined interiors and enhanced drivability. And, in a nod to Ford's Super Duty line, there's more to differentiate this newest Heavy Duty from its lighter-duty sibling.
