Construction & Design

The WeatherTech Cargo Liner is crafted from a proprietary thermopolyolefin (TPO) blend, a material known for its exceptional durability and flexibility. This ensures the liner resists cracking, tearing, and deformation even under harsh temperature extremes, from freezing winters to hot summers. The raised edges are precision-molded to trap liquids and debris, preventing them from reaching the carpet below.

The bumper protector complements the liner with a tough vinyl fabric that guards the rear bumper from scratches and scuffs caused by loading gear or pets. Its snap-on design uses stainless steel hardware to resist rust and corrosion, providing long-lasting protection without damaging your vehicle’s finish.

Installation & Fitment

Installation is straightforward and requires no modifications to your Jeep Wrangler Unlimited JK. The cargo liner fits snugly into the rear cargo area, aligning perfectly with factory contours for a seamless look. The bumper protector snaps securely onto the liner, allowing for quick attachment or removal as needed. Both components are designed for easy cleaning—simply remove, hose off, and reinstall.
