AMP Research 2004-2012 Chevy/GMC Colorado/Canyon Standard Bed Bedxtender - Black

Slant-back design lets you haul even more. Gives smaller pickups the extra enclosed space needed to secure full-size motorcycles, bikes or any extra-long cargo that you need to haul with the tailgate open. From hay bales to Hondas, it's there when you need it. And when you don't, it flips forward to keep your smaller cargo safe and organized in the truck bed.
