To create the 2019 Colorado ZR2 Bison, Chevy Trucks teamed up with high-end off-road mod specialists American Expedition Vehicles. AEV fitted the already beefy ZR2 with a total of 5 armored skid plates made of durable hot-stamped Boron steel, to protect the undercarriage from aggressive off-road action. They also designed special tubular bumpers & new fenders. There’s AEV branding throughout the truck as well as an optional dealer-mounted snorkel. This trick truck is also available with a diesel motor.
