Construction & Design

The WeatherTech Trunk Cargo Liner is crafted from a proprietary thermopolyolefin (TPO) material, specifically formulated to balance durability with flexibility. This custom blend ensures the liner withstands heavy use without cracking or warping, even under extreme temperature fluctuations. The raised lip design effectively traps liquids and debris, preventing them from reaching the carpet and causing stains or damage.

The textured finish not only enhances grip for cargo but also adds a refined look that complements the rugged interior of your Ram truck. Each liner is precision-cut using computer-aided design to guarantee a perfect fit, ensuring full coverage without interfering with cargo space or vehicle features.
