Construction & Design

The WeatherTech Cargo Liner is crafted from a proprietary custom-blended thermopolyolefin (TPO), a high-quality material known for its exceptional durability and flexibility. This advanced polymer resists cracking, fading, and wear even under harsh temperature extremes, ensuring long-lasting protection for your Ram’s cargo area. The liner’s raised edges are precision-molded to trap liquids and debris, preventing them from seeping onto your vehicle’s carpeting.

The textured finish not only adds a rugged aesthetic but also helps keep cargo securely in place, reducing movement and potential damage during transport. Designed using computer-aided technology, the liner fits snugly to the contours of your Ram’s trunk, providing comprehensive coverage without interfering with cargo space or accessibility.

Installation of the WeatherTech Trunk Cargo Liner is straightforward and requires no modifications to your vehicle. Simply place the liner into the trunk area of your 2025–2026 Ram 2500 or 3500, and it will conform perfectly to the factory dimensions. The custom fit ensures the liner stays securely in place during use, while the flexible material allows for easy removal when cleaning or when you need to access the factory carpeting.

This product is specifically designed for Ram trucks equipped with 6.7L Diesel or 6.4L 392 engines from model years 2025 and 2026, guaranteeing a precise and reliable fit.
