Construction & Design

The WeatherTech High Performance FloorLiner is constructed from premium Thermoplastic Elastomer (TPE), a material known for its flexibility, toughness, and resistance to environmental stressors. Unlike traditional rubber mats, TPE offers a softer feel underfoot while maintaining exceptional durability. This material withstands harsh weather conditions including extreme heat, cold, and moisture without cracking or warping.

The liner’s design incorporates precise laser measurements to ensure every contour and edge aligns perfectly with the Jeep Grand Cherokee L’s third-row floor. The high sidewalls and watertight sill are engineered to trap liquids and debris, preventing damage to the vehicle’s interior and simplifying cleanup.

Installation & Fitment

Installation is straightforward and requires no modifications to your Jeep Grand Cherokee L. The floor liner simply lays into place, secured by anti-skid nibs that keep it firmly positioned even during active driving. Its custom-fit design ensures no gaps or overlaps, providing full coverage and protection for the third-row carpet area.

This floor liner is specifically designed to fit Jeep Grand Cherokee L models from 2021 to 2024, guaranteeing compatibility and optimal performance.
