Protect Your Truck Bed Without Sacrificing Style Or Function

If you're serious about keeping your truck bed in top shape, the Rugged Liner C65U14 Under Rail Bed Liner is one of the smartest upgrades you can make. Built specifically for 2014–2019 GM 2500HD and 3500HD models with a 6.6ft bed, this liner offers a snug, custom fit that adds protection without interfering with bed caps or tonneau covers. Unlike spray-in alternatives, this liner is built from high-density polyethylene, giving you superior resistance to dents, dings, and scratches while still being easy to install or remove. Whether you're hauling tools, equipment, or gear for your next weekend getaway, the skid-resistant floor keeps everything from sliding around while reducing wear on your truck bed. Rugged Liner designed this system with durability in mind, so you get lasting performance without the mess or commitment of permanent coatings. The under rail fit also gives your truck a clean look and makes it easier to upgrade or accessorize later. It’s a simple way to boost your truck’s utility and keep it looking sharp for years to come.

Built Tough With Precision And Purpose In Every Inch

Engineered for heavy-duty work and real-world conditions, the Rugged Liner C65U14 is molded with exacting precision for 2014–2019 GM 2500HD and 3500HD trucks with the 6.5ft bed. The under rail design allows compatibility with aftermarket bed caps and tonneau covers while maintaining full protection of the front rail and tailgate. Its high-density polyethylene material offers impressive impact resistance, outperforming thinner liners or basic spray-on options when it comes to withstanding repeated loading and unloading. Integrated non-pooling grooves help drain water efficiently, keeping stored cargo from sitting in moisture. For users who need cargo flexibility, the built-in 2x4 slots allow for two-tiered stacking, which is perfect for separating tools from supplies or keeping delicate items elevated. Each liner is proudly assembled in Missouri and backed by a lifetime warranty, showing Rugged Liner’s commitment to American quality and long-term reliability. Designed with safety in mind, the liner also features a skid-resistant texture and secure fit to reduce shifting during transit and minimize risk under slippery conditions.
