The new Colorado ZR2 Off Road Truck Bison is the customized work of American Expedition Vehicles—the same company responsible for beasts like the Ram Prospector and the Jeep Wrangler Brute. First sightings of the Bison happened at the 2017 Specialty Equipment Market Association show in Las Vegas. Now that it’s in production, expect to see more of these animals on the roads—and trails.
The Bison has been outfitted with five additional skid plates made from hot-stamped Boron steel. Those plates protect the engine oil pan, fuel tank, transfer case, and front and rear locking differentials. In other words, you won’t have to worry about tearing out the underside of your truck going over harsh terrain. The plates come courtesy of AEV, as do the re-imagined front and rear bumpers (the front comes with a place to mount a winch while the rear has integrated recovery hooks).
As if the Bison wasn’t already beastly enough, 17-inch rims with 31-inch Goodyear Wrangler Duratrac off-road tires were added. You’ll need those tires, but not more power thanks to the 3.6 liter V6 with eight-speed automatic transmission or the 2.8 litre turbo diesel with six-speed auto gearbox.
