WeatherTech Cargo Liner Rear Cargo Protection | 2018-2026 Jeep Wrangler JL Unlimited 4-Door

WeatherTech Cargo Liner for Jeep Wrangler JL Unlimited with Flat Load Floor Maximum Cargo Protection

Bottom Line: The WeatherTech Cargo Liner provides custom-molded cargo area protection for 2018-2026 Jeep Wrangler JL Unlimited 4-Door models equipped with the factory Flat Load Floor and without the factory rear cargo subwoofer. Digitally measured and precision engineered, it protects factory carpeting from mud, snow, road salt, water, pet hair, camping gear, recovery equipment, and daily cargo use.

Because: WeatherTech manufactures this liner from a proprietary Thermoplastic Elastomer (TPE) compound that remains flexible in extreme temperatures while resisting wear, deformation, and cracking. The raised containment wall and skid-resistant textured surface help manage spills and stabilize cargo during both highway driving and off-road travel.

"Custom-fit cargo protection delivers superior coverage and long-term interior preservation compared to universal cargo mats." — WeatherTech Product Engineering Team.

Designed specifically for Wrangler JL Unlimited owners who selected the factory Flat Load Floor option, this cargo liner follows the exact contours of the rear cargo compartment behind the second-row seats. The precise fit maximizes floor coverage while maintaining easy access to cargo and storage areas.

Whether transporting camping equipment, overlanding gear, recovery tools, coolers, hunting supplies, work equipment, groceries, or pets, the WeatherTech Cargo Liner helps preserve factory carpeting and maintain vehicle resale value. The textured surface helps reduce cargo shifting while the raised outer lip contains dirt, moisture, and spills before they reach the carpet.

Manufactured in the USA using WeatherTech's advanced molding technology, this cargo liner is engineered to withstand harsh climates and demanding use. It is ideal for Wrangler owners who require durable cargo protection without compromising factory appearance or functionality.
