First-Ever Chevrolet Silverado HD ZR2 Bison

DETROIT – The off-road capability synonymous with Chevrolet’s ZR2 badge debuts for the Silverado HD with the introduction of the 2024 Silverado HD ZR2 – the brand’s flagship heavy-duty off-roader. Elevating the Silverado HD’s off-road credentials to even further heights, the 2024 Silverado HD ZR2 Bison debuts as part of the Chevy trucks family as well.

Chevrolet will soon offer a trio of flagship, off-road performance pickup trucks for anyone ready to explore the trails in Colorado ZR2, Silverado 1500 ZR2 and the first-ever Silverado HD ZR2.

Both the HD ZR2 and HD ZR2 Bison bring race-proven technologies and enhanced off-road capability to the refreshed 2024 Silverado HD lineup, with the specialized ZR2 Bison featuring unique equipment from premium off-road aftermarket manufacturer American Expedition Vehicles, for those seeking the ultimate capability in their adventures.

“The all-new Silverado HD ZR2 and HD ZR2 Bison provide the off-road performance our customers have come to expect from a ZR2, with the towing and payload capabilities our HD customers demand,” said Michael MacPhee, director of Chevrolet Trucks Marketing. “They also expand the Silverado HD lineup, offering more choices for customers to find the perfect truck for work and off-road adventure.”

Offered exclusively in the 2500 Crew Cab configuration — with the standard 6.6L gasoline engine or available 6.6L Duramax Turbo-Diesel — the Silverado HD ZR2 and HD ZR2 Bison leverage Chevrolet’s off-road racing success with a defined set of upgrades built from proven off-road prowess. Whether that’s crawling trails, tackling tough terrain or towing adventure toys on the weekend, the Silverado HD ZR2 and HD ZR2 Bison can handle it all.

The HD ZR2 is instantly recognizable with the ZR2 family’s front grille, which represents the expressive styling the ZR2 family of trucks values. Unique wheel opening moldings featuring integrated mud guards, ZR2 badging on the grille bar and a higher stance further strengthen HD ZR2’s image. Both trucks also wear the “flow-tie” emblem. The suspension is raised approximately 1.5 inches (38 mm), front and rear, compared to other Silverado HD 4WD models.

Its off-road-capable features and content also include:

  • Specific front upper and lower control arms and specific steering knuckles
  • Multimatic DSSV Dampers
  • Larger steel transfer case skid plate and front aluminum skid plate
  • Rear e-locker
  • 35-inch Goodyear Wrangler Territory MT tires mounted on 18 x 9-inch aluminum wheels.

HD ZR2 also includes a new Off-Road mode, which incorporates learnings from the Colorado ZR2 and Silverado 1500 ZR2. When engaged, it adjusts various vehicle calibrations, such as the anti-lock brakes, traction control and stability control, to optimize their performance for off-road driving. In addition, the off-road mode alters throttle progression and transmission shifts, and the locking rear axle does not have a speed limitation.
