General Motors unveiled the refreshed 2024 Chevy Silverado HD late last year, and although the automaker announced the forthcoming arrival of the new Silverado HD ZR2 trim level, specifics and details were sorely lacking. Luckily, GM has finally spilled the beans on its new heavy duty off-roader, including the new Chevy Silverado HD ZR2 Bison, which takes the pickup to the next level of off-road capability.
Similar to the Chevy Silverado 1500 ZR2 Bison and Chevy Colorado ZR2 Bison, the Chevy Silverado HD ZR2 Bison was developed in collaboration with American Expedition Vehicles (AEV), and features a variety of unique touches aimed squarely at off-road enthusiasts.
Chief among these upgrades are exclusive gloss black 18-inch AEV wheels, as well as a high-approach, stamped-steel front bumper with integrated recovery points and provisions for a winch. There’s also a unique stamped-steel rear bumper with recovery points, plus stamped steel underbody skid plates that protect the steering rack, the exhaust, and the transfer case.
Further touches include unique exterior badging, while in the cabin, the 2024 Chevy Silverado HD ZR2 Bison shows off with AEV branding in the front-seat head restraints. Interior surfaces are covered in Jet Black and Graystone leather upholstery.
The 2024 Chevy Silverado HD ZR2 Bison is available exclusively in 2500 Crew Cab configuration, just like non-Bison Silverado HD ZR2 models. Under the hood, the naturally aspirated 6.6L V8 L8T gasoline engine is standard, with output set at 401 horsepower and 464 pound-feet of torque. The 6.6L V8 L5P turbodiesel Duramax engine is optional, now rated at 470 horsepower and 975 pound-feet of torque following the recent 2024 model year refresh. Both engines connect to the Allison-branded 10-speed automatic transmission as standard.
Production of the 2024 Chevy Silverado HD ZR2 Bison will kick off this summer at the GM Flint Assembly plant located in Michigan. Official pricing information will be released closer to the start of production.
