Chevrolet Introduces Silverado ZR2 Bison

Chevrolet recently introduced the first-ever special edition Silverado ZR2 Bison in collaboration with American Expedition Vehicles (AEV), the companies announced. The truck was uniquely tuned to increase off-road capability for customers seeking overlanding adventures.

“Our most recent collaboration with AEV resulted in the much-acclaimed Colorado ZR2 Bison. We’re thrilled to team up again to bring customers Chevrolet’s next chapter of off-road dominance, this time on Silverado,” said Scott Bell, Chevrolet vice president. “The 2023 Silverado ZR2 Bison unlocks the pinnacle of the nameplate’s off-road capability.”

The 2019 Colorado ZR2 Bison quickly became the most popular special edition package offered with the Colorado ZR2, Chevrolet said. Similar to the Colorado ZR2 Bison development, AEV and GM engineers and designers collaborated on the tooling and design to bring forth the Silverado ZR2 Bison with unique overlanding componentry.

“The Chevrolet Silverado ZR2 Bison is the ultimate half-ton truck for backcountry adventures,” said AEV CEO and Founder Dave Harriton. “The Silverado ZR2 Bison checks all the boxes — robust stamped steel bumpers, complete underbody protection, a factory-tuned off-road suspension, and locking differentials front and rear. We are confident off-road enthusiasts are going to love this truck.”

When compared to the 2022 Silverado ZR2, the Bison special edition is expected to feature improved stats for overlanding adventure, Chevrolet said. The front approach angle increases to an estimated 32.5 degrees (compared to 31.8 degrees). The departure angle improves to an estimated 23.4 degrees (compared to 23.3 degrees). The trucks are expected to share the same ground clearance at 11.2 inches.

The truck is equipped with AEV-stamped steel front and rear bumpers constructed of 3-millimeter-thick steel that are powder and e-coated.

The Silverado ZR2 Bison comes standard with:

• AEV stamped steel front and rear bumpers with heavy duty recovery points and integrated step pads. The front bumper is compatible with an available winch accessory
• Five unique hot-stamped boron steel skid plates providing protection for the front, rear differential, transfer case and fuel tank
• Steel rocker panel protection
• A three-piece durable steel front bumper with integrated black, vertical front tow hooks
• Exclusive gloss black 18-inch AEV wheels paired with 33-inch Goodyear Wrangler Territory MT tires

The accessories complement the ZR2’s standard features:

• Standard 6.2L V-8 engine with 10-speed automatic transmission delivers 420 horsepower and 460 lb-ft of torque
• Multimatic 40-millimeter DSSV spool-valve dampers, which feature:
  • Three separate spool valves to control damping
  • Three connected chambers for fluid flow
• Tuned springs that, with the Multimatic dampers, increase maximum front and rear suspension travel, compared to the Silverado Trail Boss
• Front and rear e-lockers
• Specific off-road chassis and suspension calibrations, including Terrain Mode, which allows one-pedal1 rock crawling

A Silverado ZR2 Bison exclusive body-color grille bar provides contrast to the black grille design and features the ZR2 badge while the rear features a black matte finish on the standard Multi-Flex tailgate unique to the Bison design.

The Silverado ZR2 Bison customers also features nods to the AEV collaboration throughout the interior and exterior of the truck, including the Bison decal on the side outer box and the AEV badge featured on the front headrests and all-weather floor liners.
