2024 Chevrolet Silverado HD to ZR2 Off-Road Specifications

The Chevrolet Silverado HD has been updated for the 2024 model year, which includes a new ZR2 grade.

ZR2 is the brand's designation for an off-road capable pickup truck, and the Silverado HD ZR2 is a heavy-duty truck that will happily hit the trail as well as tow and haul all of your gear.

It is offered only in the 2500 Crew Cab configuration and in regular ZR2 and ZR2 Bison guise. As is the case with Chevrolet's other ZR2 trucks, the Bison was developed in conjunction with off-road outfitter American Expedition Vehicles and features upgrades designed to increase off-road capability, primarily through added protection elements.

With either version of the Silverado HD ZR2, buyers will receive Multimatic's DSSV spool valve shocks, special front upper and lower control arms, special steering knuckles, aluminum front skid plates, large steel transfer case skid plates, rear E-lockers, and 18-inch wheels with 35-inch Goodyear Wrangler Territory MT tires; the ZR2 is 1.5 inches taller than other Silverado HD trucks.

Both versions also come standard with an off-road driving mode that adjusts a number of vehicle systems, including antilock brakes and traction stability control. It also optimizes throttle and transmission settings for off-road driving.

Unique Bison features include AEV 18-inch wheels, steel bumpers with integrated recovery points and winch mounts (front only), custom badging and interior detailing, plus steel skid plates on the front of the vehicle, steering rack, transfer case, and exhaust.

The standard powertrain is a 6.6-liter V-8, but a 6.6-liter turbodiesel V-8 is also available for serious towing. When properly equipped, the diesel-powered truck has a tow rating of 18,500 pounds. Both powertrains come standard with a 10-speed automatic transmission.

For the interior, Chevrolet said it has added materials that are easy to clean after a dirty day. The Silverado HD's available heads-up display also includes an off-road inclinometer. A surround-view camera system can also be added for off-road driving.

Production of the Silverado HD ZR2 will begin this summer at General Motors' plant in Flint, Michigan. Pricing information will be announced closer to the start of production.

The related 2024 GMC Sierra HD will also be available in an off-road grade AT4X; GMC is expecting details on that truck later this year.
