The AMP Research Bed X-Tender HD Max is perfect for loading extra cargo. This truck bed extender utilizes the tailgate as a floor and extends the available space for hauling above capacity. This increases the length of your storage space by 2ft.

Lightweight aluminum construction provides easy handling and corrosion resistance. Black and Silver finishes are available for multiple styles and vehicle color schemes. These colors are applied in powder coat for the very best longevity.

AMP uses a U-shaped design for optimal increase in area and nylon uprights for strength. This bed extension can quickly and easily be flipped into the truck bed for a closed tailgate where it can still be used to keep fuel containers and other items from sliding around.
