Designed specifically for 1999-2006 GM 2500HD and 3500HD trucks with a 6.5-foot bed, plus 2007 Classic models, this liner delivers real-world toughness where it counts. It is made from high-density polyethylene, which means it handles impacts, shifting cargo, and daily abuse without cracking under pressure. Whether you are hauling tools, gear, or weekend toys, it protects your bed from dings, scratches, and wear that can ruin resale value and create long-term headaches. The liner’s non-pooling floor design helps keep water and debris from collecting, so your cargo stays drier and cleaner. Custom-molded for a snug fit, it looks like it came from the factory but performs like aftermarket armor. It is built for truck owners who do not baby their beds and need something that can keep up. Plus, with a lifetime warranty and American assembly pride built in, you are investing in protection that lasts.

Precision Molded Protection With Durability You Can Trust

Rugged Liner’s C65U99 Under Rail Bed Liner is a perfect blend of thoughtful design and rugged engineering. Every inch is custom-molded to precisely contour the 6.5-foot bed of 1999-2006 GM 2500HD and 3500HD models, as well as 2007 Classic editions, ensuring a tight fit that won't slide around or shift during use. Its high-density polyethylene construction is formulated to offer maximum impact resistance while maintaining flexibility under varying temperatures. The under-rail design keeps the liner securely nested beneath bed rails, making it ideal for use with tonneau covers or camper shells. Built-in 2x4 inserts allow for easy two-tier stacking, expanding your truck’s cargo versatility without extra tools or equipment. The liner’s surface is engineered to reduce cargo shifting while maintaining enough texture for easy cleanup.
