Chevrolet brings everything heavy-duty truck customers want and need with the 2024 Silverado HD — with no compromises in capability and comfort.

The lineup includes 2500HD and 3500HD models in Regular Cab, Double Cab and Crew Cab configurations. Dual-rear-wheel models are available on 3500HD and they support the lineup’s highest trailering capacity: 36,000 pounds. The 2024 Silverado HD is available in Work Truck, Custom, LT, LTZ, and High Country trims. ZR2 will join the HD trim lineup later in the model year for the first time.

Allison 10-speed transmission enhances gas-engine trailering capability

For the first time, the proven Allison 10-speed automatic transmission is now standard equipment for both the Silverado HD’s powertrains: the standard 6.6L V-8 gas engine and the available Duramax turbo-diesel. It replaces the gas engine’s previous six-speed automatic, offering smaller “steps” between the gears, which enables the 6.6L gas engine to hold closer to its peak power for longer periods.

The improvements translate to a more confident feeling of on-demand power, regardless of whether the truck is towing a trailer. When it comes time to tow, the 10-speed configuration helps channel every single pound-foot of torque to the tires in every gear. In turn, the 2024 Silverado HD’s Gross Combined Weight Rating with the 6.6L gas engine increases to 26,000 pounds, up from 24,000 pounds previously.

Additionally, the Allison transmission’s 10-speed design optimizes grade braking with the gas engine, with the closer gear ratios enabling greater engine-braking control. That, in addition to precise tuning for smooth shifts and quicker downshifts, complements the enhanced feeling of on-demand power, greater control, precision and refinement.

More power, more torque and greater refinement for the Duramax turbo-diesel

Silverado engineers continue to further push the renowned Duramax 6.6L turbo-diesel V-8 engine, and with the 2024 Silverado HD, they’ve issued their latest upgrades.

Overall, the horsepower and torque numbers increase to 470 hp and 975 lb-ft of torque, per SAE J1349. Additional changes and upgrades were designed to produce a more efficient combustion, which enhances overall performance. Further, engineers enhanced low-end torque production by up to 25% for improved performance at low speeds or climbing grades, and particularly when trailering.

Commanding presence

The 2024 Silverado HD has a commanding presence, driven by a freshened front-end appearance that features a new fascia, new headlights, new grille and more. The truck’s chiseled appearance combines with timeless design that not only looks, but is, prepared for anything.

C-shaped LED graphic lamps frame the new fascia, inspired by the signature design of the Silverado 1500, while bold, new headlights on LTZ, ZR2 and High Country models feature dual-projector technology. The main and high beams of these new lights are now split into dual functions, and as owners approach or depart their 2024 Silverado HD, an animated lighting sequence welcomes or bids them farewell from the truck.

Additional exterior updates include standard tow hooks, and “CHEVROLET” lettering featured on the hood scoop. Six new exterior colors have been added as well: Sterling Gray, Dark Ash, Radiant Red, Auburn Metallic, Lakeshore Blue Metallic (late availability) and Meteorite Metallic (late availability).

Atop numerous updates, Silverado HD’s design continues to boast the breakthrough features and technologies that contribute to its true truck capability. They include the Durabed cargo box that optimizes every square inch for maximum cargo capability — including up to 83.5 cubic feet with the long box — as well as the CornerStep rear bumper, BedSteps, available six-position Multi-Flex tailgate, available 120-volt power outlet, available power tailgate and more.

The lineup also retains the popular Z71 Sport Edition, Z71 Chrome Sport Edition and Midnight Special Edition appearance packages, as well as the Alaskan Snow Plow Special Edition.
