Even though the half-ton Silverado 1500 is all-new for 2014, the 2014 HD Silverados won't change over until next year. Meanwhile, a 4.10:1 axle on gasoline-engine models increases tow ratings by 4,500 pounds, the bi-fuel compressed natural gas system is available on the 2500 HD Crew Cab, and there's an available spray-on bed liner.
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.
Those who haul big loads and tow big trailers need a big truck, and the 2014 Chevrolet Silverado 2500 HD and 3500 HD deliver the size and muscle to get big jobs done. As with their GM corporate cousins, the GMC Sierra 2500 HD and 3500 HD, and the equivalent heavy-duty competitors from Ford and Ram, the Silverado HD trucks are available with a really strong gasoline V8 or a monstrously-strong turbodiesel V8. There are the usual cab configurations and cargo-bed lengths, and trim levels from basic to leather. The Silverado HD delivers enormous towing capacity – although not the best in class – and offers a bi-fuel system that allows running on gasoline or compressed natural gas (CNG) – meaning a potential cost saving, depending upon fuel prices.
