2020-2023 GM 1500 Bedxtender HD Max Black (AMP74841-01A)

Maximize the hauling potential of your Silverado or Sierra with the AMP Research Bedxtender HD Max. Featuring a classic U-shape design, this extender is engineered to provide the maximum possible cargo volume, allowing you to securely haul motorcycles, outdoor gear, or building materials with the tailgate open. When the extra length isn't required, simply flip the extender inward to create a partitioned area that prevents tools, groceries, or smaller equipment from shifting toward the cab. This rugged, high-capacity solution is the ultimate tool for GM owners who need to make the most of their truck bed space.
