POWERFUL, LUXURIOUS, HEAVY-DUTY, GENUINE MAX TOWING CAPABILITY! Denali sits at the very top of the Sierra 2500HD lineup, and this Crew Cab example takes it further still with the Duramax diesel and a genuine Max Trailering setup. Finished in Summit White, this Sierra HD pairs serious towing muscle with the kind of chrome-accented, leather-lined luxury that sets Denali apart from every other 2500HD trim. Why Shoppers Buy This Model The Sierra HD built its reputation on delivering genuine three-quarter-ton capability without sacrificing the comfort and refinement Denali buyers expect. The all-new 2024 Duramax engine architecture brought a completely redesigned combustion system with higher-flow injectors and greater fuel injection pressure, delivering meaningfully improved towing power over the outgoing generation. With this configuration's Max Trailering Package and gooseneck/5th-wheel prep, this Sierra HD is capable of best-in-class Crew Cab towing figures that put it ahead of its direct rivals.

To the best of our abilities, we believe the following warranties are still intact and not negated by GM's anti-flip rule, but you're welcome to check with an authorized GMC dealership. Standard Features Denali sits at the top of the Sierra HD lineup, and it shows in the details: heated and ventilated leather front seats, a chrome Denali grille, and 20-inch ultra-bright machined alloy wheels all come standard here, well beyond what the mainstream SLE and SLT trims offer. HD Surround Vision, a Bose premium sound system, and remote vehicle starter round out a cabin built for buyers who want genuine near-luxury refinement in a heavy-duty truck. Installed Options On top of Denali's already strong standard equipment, this Sierra 2500HD was further outfitted with genuine factory-installed content built for serious towing.

The 12-inch rear axle, HD frame, HD leaf springs, and HD shock package all work together to keep this truck composed and confident under serious loads, and with a GVWR of 11,750 pounds, this Sierra 2500HD is built for real work, not just the badge. Mechanical Features Power comes from the Duramax 6.6-liter turbo-diesel V8, B20 diesel compatible, producing 470 horsepower and a massive 975 lb-ft of torque with the kind of relentless, low-end pull that makes towing near this truck's rated capacity feel genuinely composed. The 10-speed Allison automatic transmission is purpose-built to handle that torque, while the standard exhaust brake adds real engine-braking control on long descents, especially useful when towing heavy loads. A 3.42 rear axle ratio rounds out a drivetrain tuned specifically for towing performance. Exterior Features Summit White gives this Sierra 2500HD a clean, commanding presence, and it's paired here with Denali's signature chrome grille and 20-inch ultra-bright machined alloy wheels for a genuinely upscale stance. The installed roof marker lamps with smoked amber lenses and a winter grille cover round out a truck built for both style and real-world function. Interior Features Step inside and the heated and ventilated leather front seats immediately signal Denali's top-tier positioning within the lineup, with 12-way power adjustment and lumbar support making it easy to get comfortable on long tow days. The power sunroof brings real light into the cabin, while the multicolor 15-inch Head-Up Display keeps key driving and trailering information directly in the driver's line of sight. Infotainment Features A GMC Premium Infotainment System with wireless Apple CarPlay and Android Auto keeps drivers connected without extra hassle. The installed Rear Camera Mirror adds a genuinely useful trailering aid, letting the driver see behind a trailer that would otherwise block a standard rearview mirror, while the Bose premium sound system delivers noticeably richer audio than a standard setup. Safety Features Adaptive Cruise Control comes standard here, taking the tedium out of highway driving with a heavy trailer in tow. HD Surround Vision with front and rear ultrasonic park assist makes tight maneuvering noticeably easier, while forward collision alert and lane departure warning round out a safety suite built around real confidence, loaded or not. ... and there's SO MUCH more!
