Although the GMC Sierra 1500 is mechanically the same as the half-ton Chevrolet Silverado, it adds a more upscale flavor and unique features not available on its sibling. First off is the optional power-operated MultiPro tailgate that can be configured in six different ways. You can convert it into a work surface or use it as a seat; its inner part lowers to create a full-width step; it has a built-in load stop that prevents cargo from falling out. One more distinctive feature is a lightweight yet strong bed with carbon fiber panels. Adaptive dampers are among the parts exclusive to the Sierra pickup truck as well. GMC loyalists have a whole lot of trims, options, and powertrains to choose from, enabling anyone to configure the truck they want. And with a wide variety of 2021 GMC Sierra 1500 accessories and parts that the aftermarket offers, you can add the right equipment and get everything you need to keep your vehicle in top condition, all at a reasonable price.
The 2021 Sierra full-size pickup truck remains available in the base, SLE, Elevation, SLT, AT4, and Denali trim levels, some of which come with newly offered options. The multi-function tailgate is now available for all but the base model. The off-road-ready AT4 adds a high-clearance step and a new choice of tires. Along with standard 4WD and a lift kit that adds 2 inches to the ground clearance, the Sierra’s off-road model incorporates a whole lot of purpose-built parts and accessories that allow it to go farther and look bolder, including a locking rear differential, protective skid plates, and model-specific trim accents inside and out.
The GMC Sierra 1500 maxes out at 12,200 pounds of towing and 2,240 pounds of payload. To make pulling loads way easier, GM adds a few new trailer-assist features and improves the existing ones. These include Jack-Knife Alert and Trailer Length Indicator, among other technologies. This year’s Sierra 1500 continues with five engine choices mated to 6-, 8-, or 10-speed automatic transmissions. Notable options include a torquey 3.0-liter Duramax turbodiesel that develops 460 lb-ft of twist and a 6.2-liter V8 shared with the Silverado and rated at 420 hp, which is the biggest engine in the class. Maintain the original high level of your truck’s performance or take it to new heights with 2021 GMC Sierra 1500 parts and accessories that we source from some of the most trustworthy brands.
