what does hd stand for on chevy trucks
Chevrolet C/K The C/K was Chevrolet and GMC's full -size pickup truck line from 1960 until 2000 in the United States, from 1965 to 1999 in Canada, from 1964 to 2001 in Brazil, and from 1975 to 1982 in Chile. The first Chevrolet pickup truck was introduced in 1924, though in-house designs did not appear until 1930. "C" indicated two-wheel drive and "K" indicated four-wheel drive. The aging C/K light-duty pickup truck was replaced with the Chevrolet Silverado and GMC Sierra names in 1999 in the United States and Canada, and 2001 in Brazil; the Chevrolet Silverado HD and GMC Sierra HD heavy-duty pickup trucks followed. Until this time, the names Silverado and Sierra were used to identify the trim level of the C/K trucks.
Chevrolet Silverado In 2006, Chevrolet released a special edition Silverado SS under the name "Intimidator SS" (licensed by Dale Earnhardt Inc.) to honor the late Dale Earnhardt. The truck came with several minor appearance upgrades (rear spoiler, embroidered headrests, Intimidator custom badging), but was essentially just a regular Silverado SS. Of the 1,033 scheduled trucks, only 933 were made (the remaining 100 were sold as 2007 Silverado SS "classic" bodystyle trucks before the 2007.5 MY changeover. These trucks were only available in Black Onyx exterior but could be ordered with cloth or leather interior. Also features[5]-
