Chevrolet introduced the Silverado 1500 HD in 2001 as a response to the stiff competition from Ford's F-150 Supercrew and Dodge's Ram 1500 Quad Cab. It has basically the same chassis like the Silverado 1500, but has a more powerful engine. Although the Silverado 1500 HD lasted only for 6 years, it's still highly regarded for its size, power, and functionality that can haul just about anything from furniture to Jet Skis.
2001 - 2003: The ultimate response to the competition
The first Chevrolet Silverado HD came in 2001 as a four-door cab pickup truck with a short box that measured six and a half feet. In that same year, the Silverado HD was also the only trim line among the Silverado models that was available with a rear-wheel or four-wheel drive. Apart from that, the HD was the only model to have a 6.0L Vortec V8 and a 4L80E four-speed automatic transmission. The engine, which had 300 horsepower and 360 pound-feet of torque, was specifically designed only for the Silverado HD.
Although the base trim line Silverado 1500 was the smaller version of the 2500, the difference has been redefined with the arrival of the HD. With a 153-inch wheelbase and an extended cab, the Silverado 1500 HD exceeded its predecessor's capacity. The 1500 HD's size was controlled with the help of GM's innovative Quadrasteer technology. This additional option reduced the risk of "tail waggle" by allowing the control of the rear wheels opposite from the front wheels. This reduced the turning radius which also helped in parking the long pickup truck.
2005 - 2006: The final year of the HD
After three years from its release, the Chevrolet Silverado 1500 HD went hiatus in 2004, but it came back in early 2005. There had been complaints about the ineffective breaks of the pickup which eventually led to a brake-related recall earlier in its release, and later in 2006. It was redesigned by GM with front and rear brake discs and ABS until its final year. The Silverado 1500 HD didn't have any significant upgrades in its final two years. Despite of that, it still remained as one of the sought after pickup trucks because of its size and functionality. In 2007, the Silverado 1500 HD Classic was shortly released, which had the 6.0L V8 engine with 300 horsepower. That same year was also the final production period of the HD trim line, and the pickup was sold between $30,000 and $35,000.
