For midsize truck owners who wanted the massive 35-inch tire capability of the Bison or AEV Edition but didn’t check that box at the dealership, American Expedition Vehicles (AEV) has just released a no-compromise solution. AEV is now offering fully integrated, turn-key conversion packages for the Chevrolet Colorado ZR2 and GMC Canyon AT4X.
These packages bring professional-grade off-road hardware to the factory ZR2 and AT4X trims, elevating their capability to the highest level without sacrificing factory drivability.
The headline for most enthusiasts will be the $7,975 package designed specifically for standard ZR2 and AT4X models. While these trucks are incredibly capable straight from the factory on 33-inch rubber, it is no secret that many owners eventually look to move up to 35-inch tires for better ground clearance and a much more commanding stance. Traditionally, stuffing 35s under a Colorado or Canyon requires a lift kit or aggressive trimming. That route can negatively alter the suspension geometry and ruin the highly tuned ride quality of the factory Multimatic DSSV dampers.
AEV solves this problem beautifully. Their solution utilizes the AEV HighMark Fender Flares to open up the wheel wells and provide the necessary clearance without requiring a massive suspension lift. This preserves the incredible factory ride and handling characteristics both on the highway and on the trail. You can view the full details and options directly on the AEV Colorado page and the AEV Canyon page.
What is Included in the $7,975 Package?
This package focuses heavily on stance and clearance, effectively giving a standard ZR2 or AT4X the aggressive “Bison look” with OE-level engineering.
- 35-inch Tires: A full set of BFGoodrich 315/70R17 All-Terrain KO2 tires for proven, reliable traction.
- AEV Wheels: Buyers get their choice of the race-inspired Salta XR wheels or the beadlock-capable Crestone DualSport wheels.
- AEV HighMark Fender Flares: The secret ingredient to fitting 35-inch tires while maintaining proper factory suspension geometry and full suspension articulation.
- AEV Aesthetics: The package includes the AEV Paint Appearance Package featuring custom graphics for the hood, roof, and tailgate. It also includes AEV Branding and the signature windshield banner to complete the look.
The “Bison Completion” Package
AEV certainly hasn’t forgotten about those who already own a factory ZR2 Bison or Canyon AT4X AEV Edition. For $4,570, current owners can add a “Standard Content” package to finish out their ultimate overlanding rig. This package prominently features the COMEUP Slim 9.5rs Winch. This is a synthetic rope winch boasting 9,500 pounds of pulling power, and it is designed specifically to mount perfectly inside the factory AEV stamped steel front bumper. The package also includes the custom AEV Paint Appearance Package to make the truck stand out even more on the trail.
Available Upgrades and Warranty Backing
Beyond the base packages, AEV is offering several premium add-on options to further armor and enhance these trucks. Buyers can add the legendary AEV snorkel to draw in the cleanest and coolest air possible on dusty trails. Other serious upgrade options include Hot-Stamped Boron Steel Skid Plates for incredible underbody protection, heavy-duty rear differential covers, a stamped steel rear bumper, and vertical tire mounts for the truck bed.
Perhaps the most important aspect of this announcement is the factory-level backing. Every AEV turn-key conversion is covered by a 3-year or 36,000-mile warranty. This offers serious peace of mind and proves that these upgrades are engineered and validated to perform seamlessly with the OEM platform for the long haul.
