2019 - Present

The 2020 GMC Sierra Heavy Duty has been redesigned from the ground up to combine even greater capability for towing trailers with style, and has been packed with the latest technology available on heavy-duty pickup trucks in general. An even bolder exterior design is emphasized by the new signature lighting, which includes prominent so-called “light blades,” consisting of LED daylight driving lights. LED technology is used almost everywhere on the car, including for the new headlamps, taillights, optionally available fog lamps and other elements, such as the available roof marker lights. ...

2008 - 2013

GMC released the third generation of the Sierra pickup-truck range in 2006 as a 2007 model-year for the 1500 series and the 2500 HD series in the following year as a 2008 model. GMC had over a century of experience on the market. It couldn't outsell the Ford F-Series, but it was close and offered an excellent platform able to pull more than the 1500 series. For the 2500 HD (heavy-duty), the American carmaker used a new platform, the T900, which replaced the T800 and offered better solutions and more powerful engines than its predecessor. Like its predecessor, the Sierra was availa...

2008 - 2013

General Motors released the third generation of the Sierra pickup 2500 HD series in 2007 as a 2008 model year and offered it with a choice of three cabins.

It was still good to carry a family to the mountains, as long as it was a family with small children on board. For the 2500 H...

2008 - 2013

The third generation of the Sierra pickup 2500 HP showed up in 2007 as a 2008 model, and GMC built it in three cab versions. With an increasing demand for full-size pickups and room for all family onboard, General Motors offered the Sierra with a four-door cab version named Crew Cab. Sure, it might be used as a workhorse for a crew during the week, but in the weekends, it was an excellent family companion pulling that full-size trailer behind without tearing a sweat. For the 2500 HD (heavy-duty), the American carmaker used a new platform, the T900, which replaced the T800 and offered bett...
