First-Ever Chevrolet Silverado HD ZR2 Bison

DETROIT – The off-road capability synonymous with Chevrolet’s ZR2 badge debuts for the Silverado HD with the introduction of the 2024 Silverado HD ZR2 – the brand’s flagship heavy-duty off-roader. Elevating the Silverado HD’s off-road credentials to even further heights, the 2024 Silverado HD ZR2 Bison debuts as part of the Chevy trucks family as well.

Chevrolet will soon offer a trio of flagship, off-road performance pickup trucks for anyone ready to explore the trails in Colorado ZR2, Silverado 1500 ZR2 and the first-ever Silverado HD ZR2.

Both the HD ZR2 and HD ZR2 Bison bring race-proven technologies and enhanced off-road capability to the refreshed 2024 Silverado HD lineup, with the specialized ZR2 Bison featuring unique equipment from premium off-road aftermarket manufacturer American Expedition Vehicles, for those seeking the ultimate capability in their adventures.

First-Ever Chevrolet Silverado HD ZR2 Bison

“The all-new Silverado HD ZR2 and HD ZR2 Bison provide the off-road performance our customers have come to expect from a ZR2, with the towing and payload capabilities our HD customers demand,” said Michael MacPhee, director of Chevrolet Trucks Marketing. “They also expand the Silverado HD lineup, offering more choices for customers to find the perfect truck for work and off-road adventure.”

Offered exclusively in the 2500 Crew Cab configuration — with the standard 6.6L gasoline engine or available 6.6L Duramax Turbo-Diesel — the Silverado HD ZR2 and HD ZR2 Bison leverage Chevrolet’s off-road racing success with a defined set of upgrades built from proven off-road prowess. Whether that’s crawling trails, tackling tough terrain or towing adventure toys on the weekend, the Silverado HD ZR2 and HD ZR2 Bison can handle it all.

The HD ZR2 is instantly recognizable with the ZR2 family’s front grille, which represents the expressive styling the ZR2 family of trucks values. Unique wheel opening moldings featuring integrated mud guards, ZR2 badging on the grille bar and a higher stance further strengthen HD ZR2’s image. Both trucks also wear the “flow-tie” emblem. The suspension is raised approximately 1.5 inches (38 mm), front and rear, compared to other Silverado HD 4WD models.

Its off-road-capable features and content also include:

  • Specific front upper and lower control arms and specific steering knuckles
  • Multimatic DSSV Dampers
  • Larger steel transfer case skid plate and front aluminum skid plate
  • Rear e-locker
  • 35-inch Goodyear Wrangler Territory MT tires mounted on 18 x 9-inch aluminum wheels.

HD ZR2 also includes a new Off-Road mode, which incorporates learnings from the Colorado ZR2 and Silverado 1500 ZR2. When engaged, it adjusts various vehicle calibrations, such as the anti-lock brakes, traction control and stability control, to optimize their performance for off-road driving. In addition, Off-Road mode alters throttle progression and transmission shifts, and the locking rear axle does not have a speed limitation.

Ready to Roam: Chevrolet Introduces Silverado ZR2 Bison

DETROIT – Building off the success of the recent Silverado ZR2 launch, Chevrolet introduced the first-ever special edition Silverado ZR2 Bison in collaboration with American Expedition Vehicles (AEV), a premium off-road aftermarket manufacturer. This truck was uniquely tuned to unlock new heights in 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.”

AEV has a strong track record for providing accessories that excel in overland expedition environments. The 2019 Colorado ZR2 Bison quickly became the most popular special edition package offered with the Colorado ZR2. 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

“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. 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.

This truck reaches new levels of off-road confidence also in part due to the high-quality steel integrated in the AEV bumpers and underbody protection. The AEV-stamped steel front and rear bumpers are constructed of 3-millimeter-thick steel and are powder and e-coated. The press-hardened steel used for the underbody skid plates is three-and-a half times stronger than an equivalent cold-stamped high-strength steel plate and provides incredible resistance to underbody damage.

Bolstering the truck’s resume for off-road strength, 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

Bison customers will continue to enjoy ZR2’s standard features:

  • Standard 6.2L V-8 engine with 10-speed automatic transmission delivers 420 horsepower and 460lb-ft torque to power through tough terrains
  • Multimatic 40-millimeter DSSV spool-valve dampers, which feature:
    • Three separate spool valves to control damping
    • Three connected chambers for fluid flow
  • Uniquely 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

The Silverado ZR2 Bison exclusive body-color grille bar provides contrast to the black grille design and prominently features the signature ZR2 badge on the front of the truck to the right of the iconic Chevy “flow tie.” On the rear, the bold black matte finish on the standard Multi-Flex tailgate is unique to the Bison design and allows the centered Chevrolet bowtie to stand out.

Tastefully integrated into the design, Silverado ZR2 Bison customers will enjoy discovering 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.

The Silverado ZR2 Bison is expected to start production in early 2023 with an MRSP of $78,490 with dealer freight charge included2.

Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, available in nearly 80 countries with nearly 2.7 million cars and trucks sold in 2021.

GMC Unleashes the New 2023 Sierra 1500 AT4X AEV Edition

GMC revealed the new 2023 Sierra 1500 AT4X AEV Edition today at Overland Expo Pacific Northwest. The AEV Edition pushes the already highly capable, premium off-road Sierra 1500 AT4X trim to new heights, and provides unique styling cues and extreme off-road capability.

“GMC has been a pioneer in the premium off-road space and this Sierra 1500 AT4X AEV Edition raises the bar yet again,” said GMC Global Vice President Duncan Aldred. “Our customers want an uncompromising combination of on-road technology and off-road capability. Leveraging GMC’s unwavering dedication to providing premium trucks and American Expedition Vehicle’s expertise in engineering and integrating performance-driven parts and accessories, this truck provides extreme capability, technology and comfort.”

The new 2023 Sierra 1500 AT4X AEV Edition is the most off-road capable factory Sierra 1500 ever. Updates include:

  • AEV stamped steel front and rear bumpers with heavy duty recovery points and winch capability (front bumper)
  • Five hot-stamped boron steel skid plates (front approach, steering gear, transfer case, fuel tank and rear differential)
  • Unique, race-inspired, laser-engraved 18-inch AEV Salta wheels in gloss back finish with AEV’s signature recessed valve system for added protection from rocks on the trail
  • 33-inch Goodyear Wrangler Territory MT tires
  • Updated front grille and fascia to accommodate the new bumper and larger tires, gloss black door handles and a black contrast inner tailgate
  • Exclusive AEV branding throughout the vehicle, including on bumpers, embroidered head rests and all-weather floor liners
  • Available off-road rocker panel protectors to help shield the sills and frame rails and an optional bolt-on step assist when not off-roading

“The Sierra 1500 AT4X is an incredibly formidable platform when it comes to on- and off-road performance and capability,” said AEV CEO and founder Dave Harriton. “We took our signature approach to help elevate this truck’s inherent off-road capability to the next level. We are confident customers will love the result.”

The AEV-stamped steel front and rear bumpers are constructed of 3mm, heavy-duty steel and are powder and e-coated for durability as well as UV and corrosion resistance. Additionally, this factory-installed front bumper is winch-capable, something that no other competitor in its class can match.

Five ultra-high-strength, hot-stamped boron steel skid plates help protect the underbody of the Sierra 1500 AT4X AEV Edition. This press-hardened steel is not only 3.5x times stronger than an equivalent cold-stamped high-strength steel part, but it also provides incredible resistance to gouging and bending.

When it comes time to head off-road, the Sierra 1500 AT4X AEV Edition’s bumpers and underbody protection deliver capability never before available in a factory Sierra 1500. When compared to the 2022 Sierra 1500 AT4X, the AEV Edition features improved off- road stats. The front approach angle increases by more than 27% to 32.5 degrees. The departure angle improves to 23.4 degrees (compared to 23 degrees) and the breakover angle improves to 23.0 degrees (compared to 22.7 degrees). The truck’s ground clearance also improves to 11.2 inches (compared to 10.8 inches).

The AEV edition is built on the Sierra 1500 AT4X trim that offers an exclusive premium interior and advanced off-road capability. Headline features include Multimatic DSSV dampers, front and rear e-locking differentials and two-speed transfer case with selectable modes for different off-road conditions such as Terrain mode for one pedal driving and Off-Road mode. All the while, the Sierra 1500 AT4X delivers excellent on- road comfort and trailering capability with a standard 6.2L V-8 engine. The AEV edition also features the luxury-focused and tech-infused AT4X Obsidian Rush interior. The cabin boasts full grain leather-wrapped power-massaging front seats, authentic Vanta ash wood trim, a 12-speaker Bose® Premium Series audio system and more than 40 diagonal inches of combined driver-focused digital displays — the most in its class.

Later in the 2023 model year, a new Sierra 1500 AT4X will be available with AEV- inspired enhancements, including a stamped steel winch-capable front bumper, boron steel front approach skid plate and 33-inch Goodyear Wrangler Territory MT tires. These enhancements will increase the already formidable off-road capability of the AT4X through improved approach, departure and breakover angles, as well as improved ground clearance.

The new 2023 Sierra 1500 AT4X will continue to be a balanced execution that delivers extreme off-road capability when called upon without compromising the on-road comfort, technology and capability that customers have come to expect from a GMC pickup. The new Sierra 1500 AT4X will have a max payload of 1,290 pounds and max trailering of 8,700 pounds.

The Sierra 1500 AT4X AEV Edition and the new AT4X will be available later in the 2023 model year. Stay up to date at
