Most trim levels of the refreshed 2024 Chevy Silverado HD pickup began rolling off the assembly line in early March, 2023. However, production of the off-road performance focused 2024 Silverado HD ZR2 was announced for a summer 2023 start, with the specific month previously unknown.
Now, GM Authority has learned when start of regular production (SORP) for the 2024 Chevy Silverado HD ZR2 is scheduled to kick off from sources familiar with the situation.
Production of the 2024 Chevy Silverado HD ZR2 will begin in August, according to the information gained by GM Authority. Unlike the standard 2024 Chevy Silverado HD, which is built at both the GM Flint plant in Michigan and the GM Oshawa plant in Canada, the ZR2 will be produced only at the Flint plant.
According to a GM Canada representative speaking to GM Authority about the matter, the ZR2 will be produced only at Flint for reasons of manufacturing efficiency. Notably, the off-road variants of other GM nameplates such as the Chevy Silverado 1500 ZR2 are also produced only at Flint and not at Oshawa.
Joining GM’s growing lineup of pickup variants with enhanced off-road capability, the 2024 Chevy Silverado HD ZR2 shows off trim level styling with a unique front grille, flow-tie emblem, unique wheel opening molding with integrated mudguards, ZR2 badging in the grille bar, and a 1.5-inch suspension lift giving it a taller stance.
The Silverado HD ZR2’s off-road equipment list includes Multimatic DSSV dampers, a bigger steel transfer case skid plate, a front aluminum skid plate, a rear locker, and 18-inch aluminum wheels fitted with 35-inch Goodyear Wrangler Territory MT tires.
The ZR2 also offers a new Off-Road mode that adjusts the brakes, traction control, stability control, throttle response, transmission shifts, and locking rear axle to boost off-pavement performance. An even higher-level off-road performer, the Silverado HD ZR2 Bison, debuted in April and is also on its way.
The new Silverado HD ZR2 trim level is available exclusively in the 2500 Crew Cab configuration. Standard motivation is provided by the naturally aspirated 6.6L V8 L8T gasoline engine supplying 401 horsepower and 464 pound-feet of torque, while the uprated 6.6L V8 L5P turbodiesel Duramax engine developing 470 horsepower and 975 pound-feet of torque is optional.
Both powerplants are linked to the Allison-branded 10-speed automatic transmission as standard. As far as structure is concerned, the 2024 Chevy Silverado HD rides on a more-capable variant of the GM T1 platform.
