Unveiled at the 2019 SEMA Show, the 2021 Silverado HD Carhartt Special Edition is, in fact, the road-going, street-legal offspring of the Silverado 2500 HD Carhartt concept car shown back in 2016. Only this time, you will be able to actually get one from your Chevy dealership, provided you show enough patience to wait until the fall of 2020 when deliveries are slated to kick off. Details are scarce for the time being and the 12-month waiting window is certainly far from appealing, but there are plenty of reasons to jump for joy. The Silverado HD Carhartt Special Edition is based on the Silverado 2500 LTZ, which means that in theory, it should be available with a V-8 engine. The only question is which one, as Chevy is offering a choice of two V-8s for the LTZ: a 5.3-liter and a 6.2-liter.
