The 2024 Chevrolet Silverado HD arrives with powertrain upgrades, an overhauled interior, enhancements to its trailering technology, and infotainment and active safety technology upgrades.

“We’ve designed the Silverado HD to be our customers’ favored choice for true truck capability,” said Scott Bell, vice president of Chevrolet. “The enhancements to the 2024 model build on its core strengths to provide an even stronger balance of the design, strength and confidence that makes tackling the hard jobs, including trailering, easier and more convenient than ever.”

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.

Adding the Allison 10-Speed Transmission

For the first time, according to the automaker, 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 6-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 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. 

Duramax Turbo-Diesel Upgraded 

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.

Updated Heavy-Duty Exterior

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. 

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.

In addition to the exterior styling updates, all models receive a new interior designed for greater work-ready functionality and next-level technology integration.

LT, LTZ and High Country models introduce a redesigned passenger space centered around an all-new instrument panel that houses an infotainment screen: a 13.4-inch-diagonal infotainment display. A 12.3-inch-diagonal configurable driver information center complements the new infotainment display. The infotainment screen and other controls are also canted toward the driver, giving the driver more of a “command center” perspective. This ethos pulls directly from the simple and iconic looks the C/K Series trucks set in the 1970s and 1980s, according to Chevrolet.

This command center also includes a redesigned wireless phone charger area. Ahead of the driver is an available and configurable head-up display.

“It’s a more open-feeling and contemporary interior that passengers will find inviting,” said Phil Zak, executive director of Global Chevrolet Design. “It’s an environment that intentionally puts more at the driver’s fingertips, for a greater feeling of confidence and connection with the vehicle.”

 Additional interior updates and upgrades include:

• Fresh screen displays and graphics inspired by the recently refreshed Silverado 1500

• Authentic leather-wrapped surfaces and real wood accents available on certain models

• New center console on LT, LTZ and High Country models that incorporates an available wireless charger4

• More space for side-by-side cupholders in the console: There is a total of 10 total cupholders available, depending on the model and configuration

• New audio control knobs that help strike an ideal balance between physical and digital controls, along with similar buttons recently introduced in the refreshed Silverado 1500 that allow some popular features to be accessed with a single push

• Climate vents and controls for second-row passengers

• Enhanced hidden storage, including in the console, upper and lower gloveboxes and even a sunglasses holder behind the infotainment screen

• New and improved trailering technologies

Chevrolet’s suite of customer-focused trailering technologies is designed to improve the experience with optimal visibility, easier hitching and greater driving comfort when towing a trailer. It’s improved with the 2024 Silverado HD, with a number of enhanced and new features:

• Adaptive Cruise Control with Trailer is an all-new technology for Silverado HD. It allows the Silverado HD’s available Adaptive Cruise Control to account for additional drag and increased braking distances when towing a trailer.

• Enhanced Transparent Trailer expands the current Transparent Trailer technology by allowing it to work with fifth-wheel and gooseneck trailers

• Trailer Side Blind Zone Alert extends the blind zone area of interest to help enhance safety and situational awareness when trailering

• GCW Alert warns the driver if the vehicle and trailer weight exceed the vehicle’s Gross Combined Weight Rating

The Silverado HD makes trailering easier with established available features, including up to 14 unique camera views5 such as HD Surround Vision and Bed View, an in-vehicle Trailering App6. Chevy optimized this suite of available camera views to ensure the 2024 Silverado HD provides the right view in any moment. Every Silverado HD includes a vehicle-specific Trailering Information Label, which lists its unique trailering metrics including the trailering ratings to the max tongue weight, max payload and more.

Additionally, the max tow package is now available across all Silverado 2500 trims, bolstering the maximum towing capability for the 2500HD series equipped with the 6.6L turbo-diesel V-8 engine to 22,500 pounds.

Increasing Driver Safety

When it comes to safety and driver assistance technologies, Adaptive Cruise Control is a newly available feature. It complements and bolsters the suite of standard active safety and driver assistance features that includes:

• Front Pedestrian Braking

• Forward Collision Alert

• Automatic Emergency Braking

• Lane Departure Warning

• Following Distance Indicator

The 2024 Chevrolet Silverado HD will make its public debut at the State Fair of Texas starting with the press day on Sept. 29, 2022, and the truck will be on display throughout the public days. Production begins in the first half of 2023 at General Motors’ Flint Assembly in Michigan, and at Oshawa Assembly in Canada.

Pricing and additional details will be released closer to the start of production.
