DETROIT – 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 technology2 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 pounds3. 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 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 pounds7, 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.
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.
