About This GMC Sierra 3500HD

2024 GMC Sierra 3500HD Denali Ultimate Crew Cab Dually – Sterling Metallic / Alpine Umber Leather

This 2024 GMC Sierra 3500HD Denali Ultimate Crew Cab dually is a high-end, professionally built heavy-duty truck that blends luxury, capability, and presence, showing just 8,000 miles from new. Finished in Sterling Metallic over an Alpine Umber perforated leather interior, it was purchased new by the owner and tastefully upgraded by 5R Trucks of Denver, Colorado to elevate both form and function.

Power comes from the legendary 6.6-liter Duramax turbodiesel V8, paired with an Allison 10-speed automatic transmission, dual-range transfer case, and a locking rear differential, delivering immense towing confidence with 470 horsepower and 975 lb-ft of torque.

The truck rides on a carefully engineered suspension setup featuring a Cognito 3-inch Elite leveling kit with Fox Elite 2.5 reservoir shocks up front and a Kelderman full rear 4-link air suspension, which automatically adjusts ride height based on load and allows for easier hitching and bed access. Dual rear wheels are wrapped in aggressive 37-inch Toyo Open Country tires mounted on black 20-inch ADF LTD wheels, while Kelderman Delta Series front and rear bumpers, Rigid Industries LED lighting, and subtle debadging give the truck a clean, commanding appearance. Additional exterior upgrades include a power tonneau cover, white LED marker lights, auxiliary rear lighting, and extensive paint protection film applied to the hood, front clip, bed sides, and power-folding trailer mirrors.

Inside, the Denali Ultimate cabin delivers premium comfort with heated and ventilated power-adjustable front seats, heated outer rear seats, heated steering wheel, dual-zone automatic climate control, and power-assist steps for easy entry. Technology highlights include the 13.4-inch GMC infotainment display, Bose premium audio system, digital driver display, sunroof, power sliding rear window, and advanced trailering equipment including both receiver and gooseneck hitches.

This Sierra 3500HD Denali Ultimate stands out as a no-compromise diesel dually — luxurious enough for daily driving, yet fully equipped and expertly modified for serious towing and long-haul capability.
