The Chevrolet Colorado is a capable, comfortable midsized pickup truck. With the ZR2 package, it becomes a strong off-road machine and the only small truck with dual locking differentials. Chevrolet then teamed up with American Expedition Vehicles (AEV) to add boron steel protection and gear to the Colorado ZR2 for this Bison package. It’s about as much hardcore off-road awesomeness as you can find. We had a blast with it!
