Protect your Ford Super Duty truck bed with the WeatherTech ImpactLiner, part WET39604IM. Custom designed for select 2017-2025 Ford F-250 and F-350 Super Duty models with an 8-foot bed, this heavy-duty bed liner helps shield the factory bed from dings, dents, scratches and everyday wear caused by lumber, tools, paver bricks, furniture and other cargo. Its laser-measured design follows the complex contours of your truck bed for a precise fit and dependable coverage. The black finish provides a clean, professional appearance while helping your truck bed maintain a like-new look.
Made from the same durable injection-molded material used in WeatherTech FloorLiner HP products, the ImpactLiner offers a strong alternative to traditional spray-in bed liners. It can also be installed over an existing spray-in liner to add another layer of protection. Patent-pending raised impact rings on the underside help disperse the force of impacts while elevating the liner to promote airflow beneath it, allowing moisture to escape. Textured ribbing across the top surface adds traction to help reduce cargo movement during transport.
Raised side and rear walls help protect the surrounding bed surfaces and contain spills, while the scratch-resistant, UV-stable material is designed to resist fading and withstand demanding use. Unlike spray-in liners that require professional installation, the WeatherTech ImpactLiner ships ready for convenient do-it-yourself installation. It is also easier to clean and maintain because the material does not attract dust and dirt as readily as many other bed liner surfaces. Proudly designed, engineered and manufactured in the USA by WeatherTech using American raw materials, this custom truck bed liner delivers durable protection for work, hauling and everyday use.
