Overview

GMC introduced the luxurious Denali trim to its pickup catalog in the early 2000s and has expanded it to its heavy-duty truck like. The GMC Sierra 2500HD Denali is available only with four-wheel drive and can be had with a long or standard bed. No matter how it’s configured, the truck sports a crew cab body style. As a flagship trim of one of GMC’s most popular trucks, the 2500HD Denali gets the best features, an upscale interior, massive capability, and a heavy price tag to match.

Key Features

  • Standard 6.6-liter gas engine, available diesel
  • Six-speed heavy-duty transmission
  • Four-wheel drive
  • Trailering assistance functions
  • Available Allison ten-speed transmission

Pricing Details

The 2022 GMC Sierra 2500HD Denali starts at $71,395. Stepping up to the 6.6-liter turbodiesel option adds a whopping $11,000 to the price tag but brings 910 pound-feet of torque and an Allison transmission. Used examples on CarGurus range from $19,913.00 to $95,062.20 with an average price of $24,831.57.
