Tough Enough To Handle Every Load You Throw In

Whether you’re tossing in bags of gravel, hauling tools for the jobsite, or heading out with weekend gear, the Rugged Liner C67U20HD Under Rail Bedliner is built to keep your truck bed protected from it all. Made from thick, high-density polyethylene, this liner delivers serious defense against scratches, dents, and wear that can break down your truck bed over time. It’s custom molded to fit 2020-2024 GM 2500HD and 3500HD models with a 6.9-foot bed and no factory storage boxes, offering a seamless look and snug fit. The under rail design keeps the liner tucked neatly below the bed rails, allowing compatibility with most bed covers and accessories. The skid-resistant surface helps keep your cargo from sliding around while the non-pooling floor design means water and debris won’t gather in low spots. Backed by a lifetime warranty and proudly assembled in Missouri, this bedliner is a long-term investment in the life of your truck. Tough, affordable, and designed to work as hard as your truck does.

Built With Engineering That Works As Hard As You Do

The Rugged Liner C67U20HD is more than just a protective shell, it’s a purpose-built solution designed with practical features and long-term reliability in mind. Its dense polyethylene structure is engineered for impact resistance, meaning it absorbs the brunt of heavy drops and sharp gear without warping or cracking. Molded specifically for your GM truck, it includes integrated 2-inch by 4-inch slots that allow you to build two-tiered cargo platforms for better load organization. Front rail and tailgate protection are built-in, shielding the highest-contact zones from abuse over time. The liner’s texture is not only skid-resistant but also reduces wear from vibration and shifting cargo. While it installs quickly with basic tools, proper securing is crucial to prevent lift during highway speeds. And with its resistance to pooling water, it helps you avoid corrosion and buildup in the bed. For those who value both protection and utility, this liner gets the job done without compromise.
