Chevy is collaborating on tooling and design with American Expedition Vehicles, an off-road aftermarket manufacturer, on the Bison. Chevy and AEV introduced the Bison on the Colorado midsize pickup in 2019.
"We're thrilled to team up again to bring customers Chevrolet's next chapter of off-road dominance, this time on Silverado," Scott Bell, Chevrolet vice president, said in a statement. "The 2023 Silverado ZR2 Bison unlocks the pinnacle of the nameplate's off-road capability."
Production is expected to begin in early 2023. It will start at $78,490 including shipping.
The Bison edition is expected to offer more off-roading capability than the 2022 Silverado ZR2, with sharper front approach and departure angles. Both the ZR2 and the ZR2 Bison are expected to have 11.2 inches of ground clearance.
The front and rear bumpers are equipped with AEV 3-mm-thick steel and are powder-coated and e-coated. The press-hardened steel used for the underbody skid plates is three and a half times stronger than a cold-stamped high-strength steel plate, which prevents underbody damage, GM said.
The Bison comes standard with AEV stamped front and rear bumpers, five unique hot-stamped boron steel skid plates, steel rocker panel protection, a steel front bumper with vertical front tow hooks and 18-inch AEV wheels with 33-inch Goodyear Wrangler Territory MT tires.
