Chevrolet brings everything heavy-duty truck customers want and need with the 2024 Silverado HD - with no compromises in capability and comfort. The 2024 Silverado HD arrives with powertrain upgrades, a more commanding presence paired with an overhauled interior, enhancements to its revolutionary trailering technology, and infotainment and active safety technology upgrades. 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.
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.
Welcome to High Country
High Country is the most expressive and meticulously crafted trim in Chevrolet's lineup - the 2024 Silverado HD elevates it further. Topping the updates are a new and 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.
