From the light-duty Sierra 1500 series to the Sierra 2500 HD and 3500 HD, you’ll get a high-performing powertrain and drivetrain with a roomy, comfortable interior.

With several levels and numerous configurations, the GMC Sierra 1500 is a workhorse suitable for off-roading, taking equipment to the job site, hauling supplies around the ranch, or for towing a boat to the lake. The GMC Sierra 1500 stacks up against any other pick-up truck on the market, including the Chevy Silverado 1500, Ram 1500 and Toyota Tacoma.


The SLE trim level features a 2.7-liter four-cylinder engine that delivers 310 horsepower and pairs with an eight-speed automatic transmission. The rear-wheel drive allows for 6,900 pounds of towing capacity and can seat sis. There is an optional 5.3-liter V-8 engine with 355 horsepower that pairs with a 10-speed automatic transmission. The SLE comes as a crew cab or double cab, and it has an optional four-wheel drive.


The Elevation trim comes as a rear-wheel drive or four-wheel drive. The crew and double cab seat six, while the regular cab seats three. It features a 2.7-liter four-cylinder engine that delivers 310 horsepower and pairs with an eight-speed automatic transmission.

1500 Variants

The Sierra 1500 Limited has slightly different features than the regular Sierra 1500. The Limited comes with a standard double cab, a trailering package, and an automatic locking rear differential, which helps to increase its off-road capability.

The older Sierra 1500 HD version is a half-ton truck with a 6-foot cargo bed, four-door crew cab, and features a 6.0-liter V-8 engine with a heavy-duty four-speed transmission. The rear-wheel-drive HD version has a towing capacity of 8,200 pounds. The Sierra 1500 HD makes for a solid choice when looking for a used pickup truck.

Another option for a used pickup is the Sierra 1500 Classic, which debuted in 2007. The Classic model offers several engine sizes including a 195-horsepower 4.3-liter V-6, a 285 horsepower 4.8-liter V-8, a 295-horsepower 5.3-liter V-8, and a 310-horsepower 5.3-liter V-8. The engines pair with a heavy-duty four-speed transmission that can tow up to 8,100 pounds and comes in either two-wheel or four-wheel drive. The Sierra Classic also comes in an HD version.

No matter what version or trim level of the Sierra 1500 you choose, they all come with a roomy interior, plenty of safety features, and the kind of reliability you would expect from a GMC pickup truck.
