The incredible engines only better the premium look and feel of the 2023 GMC Sierra HD models. The HD stands for Heavy-Duty and applies to two versions of this GMC truck. You can select either the three-quarter-ton Sierra 2500HD or the one-ton Sierra 3500HD. Either way, you’ll have a truck with impressive power and performance. The question you have to answer is which GMC Sierra HD is the right truck to buy?

Five trims give you lots of options for the GMC Sierra HD

Whether you choose the 2500HD or 3500HD model of the heavy-duty Sierra pickup, you’ll have five trims offered. These trims are:

• Pro
• SLE
• SLT
• AT4
• Denali

The Pro trim is the most basic, with standard features, and a regular cab configuration, while the Denali is the most luxurious, offering all the bells and whistles you could ask for. If you desire an off-road-focused version of the Sierra HD, the AT4 model is what you want to drive.

How good does your heavy-duty GMC truck look?

Even though beauty is in the eye of the beholder, we can all recognize an attractive truck when we see it. The 2023 GMC Sierra HD is an attractive and bold truck. This pickup is big and only gets bigger when you go from the 2500HD to the Sierra 3500HD models.

Depending upon the trim and the exterior packaging, you can have your desired appearance. For example, the Sierra HD AT4 offers a rugged appearance with red tow hooks and black accents. The Denali brings a flashy chrome grille and shiny wheels to the mix, while the Denali Black Diamon Edition has:

• Unique 20-inch high-gloss black wheels
• Power running boards
• LED lighting
• MultiPro audio system by Kicker in the bed
