Key Features

Engineered with cutting-edge technology and attention to detail, the WeatherTech FloorLiner HP Rear offers a range of features designed to maximize protection and usability:

• Custom laser-measured fit for 2019–2026 Ram 2500/3500 Mega Cab rear footwells ensures precise coverage without gaps.
• Constructed from a durable Thermoplastic Elastomer (TPE) compound that is both soft to the touch and highly resilient.
• Advanced retention system with non-slip nibs keeps the liner securely locked in place, preventing unwanted movement.
• Beveled edges maintain stability by preventing the liner walls from curling or folding inward.
• Watertight sill design around retention clasps prevents liquids and debris from leaking onto the vehicle’s carpet.
• Latex and PVC-free material composition makes the liner environmentally friendly and 100% recyclable.
• Optimal side trim lines expose the vehicle’s seal plate for a seamless, factory-like appearance.
• Resistant to cracking, curling, and breakdown even under extreme weather conditions.

Construction & Design

The FloorLiner HP is crafted from a proprietary Thermoplastic Elastomer (TPE) compound, combining the flexibility of rubber with the toughness of plastic. This advanced material ensures the liner remains pliable in cold temperatures and durable under heat, resisting cracking and warping over time. The tan color option is designed to blend naturally with many Ram interior trims, providing a clean and integrated look.

Each liner is laser-measured and molded to the exact contours of the Ram 2500 and 3500 Mega Cab rear footwells, ensuring full coverage of the carpeted surfaces as well as the front, back, and sides of the footwell area. The design includes a raised lip to trap dirt and liquids, preventing them from spreading to the vehicle’s interior.

Installation & Fitment

Installation is straightforward and requires no modifications to your vehicle. The FloorLiner HP fits directly into the rear footwell of compatible Ram Mega Cab models and secures firmly using the vehicle’s existing retention system. Non-slip nibs on the underside of the liner engage with the carpet to prevent shifting during use, ensuring a stable and secure fit. This product is designed specifically for the rear seating area of 2019–2026 Ram 2500 and 3500 Mega Cab trucks equipped with 6.7L Diesel or 6.4L 392 engines.
