The Colorado ZR2 Bison has no powertrain changes over the regular ZR2. It's available with either an extended cab or crew cab body.

The Bison version of the Silverado would add off-road capability to the ZR2. This model already has a lifted suspension with 40-millimeter Multimatic DSSV spool-valve dampers. Revised springs increase front and rear wheel travel in comparison to the Trail Boss trim.

There are upgraded bumpers that provide a 31.8-degree approach angle, 23.4-degree break-over angle, and 23.3-degree departure angle. A skid plate protects the underbody. The truck has 11.2 inches of ground clearance. It rides on 18-inch wheels with 33-inch mud-terrain tires.

The Silverado ZR2 has a 6.2-liter V8 making 420 horsepower (313 kilowatts) and 460 lb-ft (624 Newton-meters) of torque. There's a 10-speed automatic transmission. Locking front and rear differentials provide more traction in slick situations. The truck has a max payload of 1,440 pounds and a tow rating of 8,900 pounds.
