Sharing its cab with the K2XX-generation Silverado, the medium-duty Silverado was designed with a dedicated chassis with a forward-tilting hood; both 42 and 44 configurations are produced. As of current production, the model line is offered with a 350 hp 6.6L Duramax turbodiesel V8; the engine is paired with a choice of Allison automatic transmissions, depending upon the truck's intended usage.[3][13][16]
