The 2024 Chevrolet Silverado HD hauls in more power, enhanced interior and smarter technology. The Allison 10-speed automatic transmission is now standard for both the 6.6L gas and 6.6L Duramax turbo-diesel engines. A new interior for the LT trim and above features an all-new 13.4-inch-diagonal infotainment screen and a 12.3-inch-diagonal driver information center. Trailering technology includes four new or enhanced features designed to inspire confidence and make towing easier. The 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.
