Construction & Design

The FloorLiner HP Rear is crafted from an advanced Thermoplastic Elastomer (TPE) compound that combines the flexibility of rubber with the durability of plastic. This material is engineered to withstand extreme temperatures, heavy wear, and exposure to chemicals without degrading. Unlike traditional floor mats, the TPE compound remains pliable in cold weather and resilient in heat, ensuring long-lasting protection.

WeatherTech’s precision laser measurement process guarantees a perfect fit that contours precisely to the rear footwell of Ram 2500 and 3500 Mega Cab trucks. The liner’s raised edges and deep channels trap dirt, water, and debris, preventing them from spreading onto your vehicle’s carpet. The retention system and non-slip nibs keep the liner firmly in place, eliminating movement and enhancing safety.

Installation & Fitment

Installation of the WeatherTech FloorLiner HP Rear is straightforward and requires no modifications to your vehicle. Simply position the liner in the rear footwell of your Ram 2500 or 3500 Mega Cab, aligning it with the factory floor contours and retention points. The specially designed retention system will lock the liner securely, preventing any shifting during vehicle operation. This ensures a hassle-free installation process that can be completed in minutes.

Designed exclusively for 2019–2022 Ram 2500 and 2019–2026 Ram 3500 Mega Cab models equipped with 6.7L Diesel or 6.4L 392 engines, this FloorLiner HP Rear guarantees a precise fit and maximum coverage for your truck’s rear interior.
