GM Authority first reported on the new Chevy Silverado HD ZR2 in March, later spotting a prototype model on the road in May, followed by a chassis mule in June. Unsurprisingly given the name, the upcoming 2024 Chevy Silverado HD ZR2 will incorporate a wealth of enhancements to make the 2024 Chevy Silverado HD even more capable off-road, including greater ground clearance and more traction on loose surfaces.
Standout upgrades will include revised front and rear bumpers that will provide more aggressive approach and departure angles, with the overall bumper designs likely taking inspiration from the light-duty Chevy Silverado 1500 ZR2. The new bumper treatment will pair with extensive underbody protection and skid plates, plus a set of 35-inch Goodyear Wrangler Territory MT tires.
The drivetrain will also include front and rear locking differentials. Notably, the 2024 Chevy Silverado HD ZR2 will only be available in a single-rear-wheel configuration, and will not be offered in a dual-rear-wheel (or “dually”) configuration.
As for powertrain, the 2024 Chevy Silverado HD ZR2 is expected to offer both the atmospheric 6.6L V8 L8T gasoline engine, as well as the upgraded 6.6L V8 L5P turbodiesel Duramax. To note, the new Duramax engine now produces more output than it did prior to the 2024-model-year refresh, topping out at an SAE-certified 470 horsepower and 975 pound-feet. Both the diesel engine and the gasoline engine connect to the Allison 10-speed automatic transmission as standard.
Production of the 2024 Chevy Silverado HD is set to begin in H1 of the 2023 calendar year, while the new Chevy Silverado HD ZR2 won’t arrive until later on in the model year. Exact pricing details are still forthcoming.
