Back in early March 2023, GM Authority reported that production of the refreshed 2024 Chevy Silverado HD had finally kicked off at the GM Flint plant in Michigan after its big unveiling in September 2022. Now, production of the revised heavy-duty pickup truck has commenced at the GM Oshawa plant in Canada.
In a recent social media post, GM Canada showed off a Black (color code GBA) 2024 Silverado HD LTZ rolling down the assembly line at the Oshawa plant, equipped with the Z71 package and optional 20-inch Chrome aluminum wheels (RPO code SKW). Notably, this facility is the only GM plant that currently manufactures both light-duty and heavy-duty pickup trucks.
As a reminder, the mid-cycle refresh for the 2024 Chevy Silverado HD features a new front fascia that is highlighted by revised headlamps and a new grille design, the former of which incorporates a new C-shaped LED lighting scheme. The exterior paint list also includes six new hues, and there are new wheel and tire options as well, while all models are now equipped with tow hooks as standard fare.
For all LT and above trim levels, the interior has been completely overhauled and now features a 13.4-inch infotainment screen and 12.3-inch diagonal configurable driver information center. Notably, lower trim levels will still wear the pre-refreshed interior.
Under the hood, the 2024 Silverado HD is equipped with the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower and 464 pound-feet of torque, as standard across all trim levels. The optional 6.6L V8 L5P turbodiesel Duramax engine, which has been uprated to 470 horsepower and 975 pound-feet of torque for the refresh, is also available. New-for-2024 is the transmission situation, where both engines are equipped with the Allison-branded 10-speed automatic transmission as standard.
