The Chevrolet brand of Detroit’s General Motors Co. has debuted the 2024 Silverado HD 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,” says 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.
For the first time, the Allison 10-speed automatic transmission is now standard equipment for both Silverado HD powertrains — the standard 6.6-liter 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 engine to hold closer to its peak power for longer periods.
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 6.6-liter 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 tuning for smooth shifts and quicker downshifts, complements the enhanced feeling of on-demand power, greater control, precision, and refinement.
Overall, the horsepower and torque numbers increase to 470hp and 975 lb.-ft. of torque. 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 percent for improved performance at low speeds or climbing grades, and particularly when trailering.
New wheel and tire options for the Silverado HD include 20-inch bright chrome wheels available on LTZ; 18-inch polished aluminum dually wheel and all-terrain tires optional on 3500HD LTZ and standard on 3500HD High Country; and 20-inch off-road tires available on Z71 Sport Edition, Midnight Special Edition, Alaskan Snow Plow Special Edition, and Z71 Off-Road package.
The 2024 Silverado HD features a new 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 new headlights on LTZ, ZR2, and High Country models feature dual-projector technology.
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).
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 received 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 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 smarter command center also includes a redesigned wireless phone charger area to reduce distractions and a flow-under console. The latter design provides the spaciousness of a bench seat while retaining the functionality of a center console. 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,” says Phil Zak, executive director of global design at Chevrolet. “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 authentic leather-wrapped surfaces and real wood accents available on certain models; more space for side-by-side cupholders in the console, with total of 10 total cupholders available; climate vents and controls for second-row passengers; and enhanced hidden storage, including in the console, upper, and lower gloveboxes, and a sunglasses holder behind the infotainment screen.
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 including adaptive cruise control with trailer, which accounts for additional drag and increased braking distances when towing a trailer; enhanced transparent trailer expands the current 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; and GCW alert warns the driver if the vehicle and trailer weight exceed the vehicle’s gross combined weight rating.
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 6.6-liter turbo-diesel V-8 engine to 22,500 pounds.
The High Country trim features an exclusive Nightshift Blue interior, which includes Jet Black and Umber elements. The cabin also wears new metal “High Country” badges on the center console and “High Country” embroidering on the head restraints, upholstered with unique Ares leather seating surfaces that feature a wingtip pattern.
The seats also feature premium fabric piping, while the door panels include fabric piping and trim with authentic open-pore wood. The wood additionally serves as a decorative trim on the upper glovebox. On the exterior, a new High Country exclusive 20-inch bright chrome wheel design is standard.
Additional High Country details and standard features include power-adjustable heated and ventilated front seats with memory and haptic sensors, acid-etched stainless steel speaker grilles for the standard Bose seven-speaker audio system, rain-sensing wipers, and wireless charging located in the center console.
The 2024 Silverado HD High Country trim will also be available with a new Midnight Edition. Available for the first time on the High Country trim, the Midnight Edition darkens the exterior with black chrome accents in the grille and grille bar and swaps in black badging. Black power assist steps complete the look. The Silverado HD High Country Midnight Edition also includes 20-inch, high-gloss black painted wheels as standard, with 22-inch wheels in the same finish available.
