The Colorado ZR2 Bison joins Chevrolet's midsize truck lineup as an all-new performance variant. Bison is Chevy's first collaboration with American Expedition Vehicles (AEV), a premium off-road aftermarket manufacturer.

For maximum protection of key undercarriage elements while driving over rocky, jagged terrain, Bison features five skid plates covering the engine oil pan, fuel tank, transfer case and front and rear locking differentials. Designed by AEV, these skid plates are constructed of hard, durable hot-stamped Boron steel.

AEV-designed stamped steel front and rear bumpers further shield the truck from obstacles. The front bumper contains winch provisions and standard fog lights, with recovery points integrated into the rear bumper.

An exclusive, flow-through "CHEVROLET" lettered grille replaces the traditional bowtie on Bison's front end. The 31-inch Goodyear Wrangler Duratrac off-road tires sit beneath larger fender flares and wrap all-new, ZR2 Bison-specific 17 x 8-inch aluminum wheels.

This new Colorado variant also features "Bison" decals on the bed sides, an "AEV Bison" logo on the tailgate and embroidered AEV logo floor liners and front head restraints.

The ZR2 Bison also duplicates the full equipment list of the Colorado ZR2, including, but not limited to: Class-exclusive front and rear locking electronic differentials; Revolutionary, segment-exclusive Multimatic DSSVTM dampers; Off-road rocker protection; Cast-iron control arms; and Autotrac transfer case.

Like ZR2, Bison also features a modified rear axle with a 3.42 ratio, front and rear tracks widened by 3.5 inches and a factory suspension lifted 2 inches over a Colorado Z71. Available options on Bison include: 2.8L Duramax Turbo-Diesel engine paired with a six-speed automatic transmission, capable of 186 horsepower and 369 lb-ft of torque, along with the choice of crew- or extended cab configurations (including short and long beds).
