The 2024 Chevrolet Colorado ZR2 Bison arrives as an even more extreme version of the off-road-focused ZR2 model. With the Bison treatment, Chevy's mid-size pickup truck gets notable upgrades such as 35-inch off-road tires as well as front and rear hydraulic bump stops. The automaker's partnership with aftermarket supplier American Expedition Vehicles (AEV) also includes add-ons such as wider fender flares, unique steel front and rear bumpers, and stronger underbody armor.
The Bison stands 1.5 inches higher than the regular Colorado ZR2, thanks largely to its taller tires, which are 35 inches in diameter versus 33 inches.
The Colorado ZR2 Bison is powered by a turbocharged 2.7-liter four-cylinder that makes 310 horsepower and 430 pound-feet of torque—same as the regular ZR2.
Along with an eight-speed automatic transmission and all-wheel drive, the Bison comes standard with electronic locking front and rear differentials.
Among the truck's AEV-supplied parts are wider front fenders and a full-length steel front bumper with a winch accommodation, and the rear bumper has steel corner plates.
Whereas the regular Colorado ZR2 features three aluminum skid plates, the Bison has five Boron steel plates, with the extra two protecting the fuel tank and rear differential.
Multimatic's hydraulic bump stops (left) are exclusive to the Bison model. With one mounted at each of the four corners, they're designed to help the truck survive hard landings as well as the abuse of aggressive off-road driving.
