Bushwacker Ultimate BedRail Caps have earned their name. They stand up to hard use, protecting your truck bed’s top edge from dents, dings, and scratches. They’re also great at covering minor damage. Ultimate BedRail Caps are made in the USA from our exclusive Dura-Flex(R) 2000 TPO, the same ultra-tough material we use to make Trail Armor(R) for Jeeps. They’re extra thick, to absorb impact and resist warping. And, they’re 100% UV protected, to prevent chalking. For all that toughness, they install easily with their doubly secure 3M adhesive and Bushwacker’s proprietary screw-clip system. Your bed rail caps are engineered specifically for your GMC so they fit factory-tight, with close tolerances and smoothly finished edges. For perfectly fitted bed rail protection, nothing else matches the Ultimate. Ultimate BedRail Caps from Bushwacker.
