Bison are getting bigger.
Learning from little brother Chevy Colorado, the full-size Silverado pickup is gaining yet another rugged off-road trim: the ZR2 Bison that's been popular on the midsize pickup since its 2019 model year introduction. Topping the Silverado Trail Boss and ZR2 off-road models, Bison takes the unique suspension, tires and style of the ZR2 — then straps on battle armor.
Chevy partnered with acclaimed aftermarket builder American Expedition Vehicles to equip Bison with rocker protection, unique skid plates and custom front bumper — continuing a partnership that began with the Colorado ZR2 Bison.
