CHEVY & AEV PRODUCE ZR2 BISON
“Modified for extreme off-road use” is how Chevrolet describes the 2019 Colorado ZR2 Bison, a collaboration between the automaker and American Expedition Vehicles (AEV) that goes on sale in January. AEV designed several components to further ruggedize the ZR2, including stampedsteel front and rear bumpers with provisions for a winch in front and integrated recovery points in back. Five skidplates made from hot-stamped Boron steel cover the engine oil pan, fuel tank, transfer case, and front and rear differentials. A new grille has flow-through “Chevrolet” letters instead of the traditional Bowtie emblem. Larger fender flares cover the
31-inch Goodyear Wrangler Duratrac tires, which are mounted to Bison-specific 17x8 alloy wheels. The snorkel seen in the photos will be an option available from AEV.
The Bison retains the equipment specific to the ZR2 upgrade: a track width 31⁄2 inches wider than the Colorado
Z71, a 2-inch factory suspension lift, Multimatic DSSV dampers, and front and rear locking differentials. The Bison will be available in crew- or extendedcab configurations, short and long beds, and with either the Colorado’s 3.6L gas V-6 or 2.8L turbodiesel engine.
