Our 2021+ F-150 & Raptor Bed Channel Stiffeners fix a common problem faced by truck owners. The bed channels of pickup trucks are susceptible to cracking and damage over time, especially when subjected to heavy payloads, fifth-wheel mounts, overland bed racks, camper shells, or off-roading stresses. The brackets provide rigidity to help minimize the sheet metal of the truck bed from extreme torque. Our brackets add an extra 3/8-inches of steel, composed of a 3/16-inch stiffener and a 3/16-inch backer plate. At the top of each bracket are accessory mounting locations suitable for accessories like a whip flag or antenna mount. Keep your F-150 going strong for years to come with our heavy-duty bed channel stiffeners. As always, these are Made in America.* Please Note: Some drilling is required for installation.
