The GMC Sierra 2500 Heavy Duty Truck

GMC proudly produces a line of heavy-duty trucks that offer practicality, utility, and dependability as well as power and performance. The GMC Sierra 2500 offers a quick, smooth, and responsive powertrain along with a remarkable trailer assist technology package that enhance your towing and hauling cargo experience. This truck was built to do work.

Performance
The 2021 GMC Sierra 2500 offers one of the best diesel powertrains on the road today. Choose from a variety of trims to add four-wheel drive capabilities to your 2021 GMC Sierra 2500HD and you’ll find that towing and hauling – on or off the beaten path – takes place with ease. Opt for the 2021 GMC Sierra 2500HD AT4, and you’ll find capability that goes anywhere. Let’s take a look at the power train of the GMC Sierra 2500. The standard engine is a 6.6-liter V8 engine. This hefty engine is partnered with a six-speed automatic transmission (you can opt for either rear wheel or all-wheel drive). Should you opt for the power Duramax diesel motor, a 6.6-liter diesel engine that offers 445 horses under the hood and 910 lb-ft of towing power, you’ll find that towing and hauling is done with ease. Keep in mind that customers can also add to the power and performance of the GMC Sierra 2500 by opting for the Duramax motor with an Allison transmission.

Interior/Exterior Options
The interior of the 2021 GMC Sierra is surprisingly spacious. It offers a large dashboard and lots of leg room both in the front and on rear seats. GM carries on tradition while setting the Sierra HD apart in that it offers heads-up display so that you don’t get distracted from the road. You’ll also find that there are options to upgrade to a leather-wrapped, heated steering wheel, heated and cooled front seats, and wireless charging. You can also opt for bucket seats in the front of the Sierra 2500. The GMC Sierra can be found in a number of cab and bed length options to fit your specifications. There is the traditional regular cab that seats up to three people. The Double Cab offers two rows of seats and can be paired with either the eight-foot bed or the six-foot bed. The four door Crew Cab is the primary offering on the AT4 trim package as well as the Denali. It offers even more storage and leg room. It can also be paired with the six foot or the eight-foot bed.

Trim Options
The base trim of the GMC Sierra 2500 offers LED lighting and headlamps, Bluetooth capability, and a backup camera. The SLE trim offers keyless entry, a WiFi hotspot, an EZ lift tailgate, and OnStar services. The SLT offers the GMC exclusive MultiPro tailgate, as well as LED lights in the bed as well as LED daytime running lamps, eighteen-inch aluminum wheels, and adjustable mirrors to make hauling trailers safer. You’ll also find that the upholstery is upgraded to perforated leather seats, which are heated and cooled. Remote start, an upgraded audio system, and an eight-inch touch screen is also a part of the SLT package. One extra nice feature is hitch guidance and hitch view. The AT4 is a great trim for those who want to go off-road (or may be required to do so for work). The Allison ten speed transmission is standard; a lifted suspension and underbody protection is also standard. An essential part, the Autotrac transfer case is also a part of the AT4 package. The Denali is the top trim level of the GMC Sierra 2500. You’ll get every luxury amenity you could imagine as well as available off-road capability present in the AT4 trim.
