WeatherTech Cargo Liner w/ Bumper Protector | 2018-2026 Jeep Wrangler JL Unlimited 4-Door

WeatherTech Cargo Liner with Bumper Protector for 2018-2026 Jeep Wrangler JL Unlimited 4-Door

Bottom Line Up Front: The WeatherTech 401171SK Cargo Liner with Bumper Protector provides precision-fit cargo protection for 2018-2026 Jeep Wrangler JL Unlimited 4-Door models equipped with the fold-flat cargo floor and without the factory rear cargo subwoofer. Designed using advanced laser measurements, it delivers exceptional containment for mud, snow, water, pet hair, recovery gear, camping equipment, and everyday cargo while helping preserve factory interior surfaces.

Because: WeatherTech utilizes digital laser-scanning technology to achieve vehicle-specific coverage, while raised containment walls and proprietary TPE construction help trap liquids, debris, and spills before they reach factory carpeting. The integrated bumper protector adds an additional layer of protection during loading and unloading.

"Vehicle-specific cargo liners offer superior protection, coverage, and retention compared to universal cargo mats." — A widely accepted principle among automotive interior protection engineers and aftermarket vehicle accessory specialists.

The WeatherTech Cargo Liner is engineered specifically for Jeep Wrangler JL Unlimited owners who demand maximum interior protection without sacrificing functionality. Whether transporting recovery gear, camping equipment, pet crates, hunting supplies, groceries, tools, sports equipment, luggage, or overlanding accessories, the liner helps keep the factory cargo area protected from wear and contamination.

Unlike generic cargo mats, the 401171SK is digitally laser measured to match the contours of the Wrangler JL Unlimited cargo area. This precise fit provides superior coverage and helps prevent debris from migrating underneath the liner.

One of the most valuable features is the integrated bumper protector. When loading coolers, toolboxes, generators, camping equipment, pet carriers, or cargo cases, the fold-out bumper protector shields the painted rear bumper from scratches, abrasions, and scuff marks. Once loading is complete, the protector folds neatly back into the cargo area.

WeatherTech's proprietary thermoplastic elastomer (TPE) material is engineered to remain flexible in cold temperatures while maintaining structural integrity in hot conditions. This makes it particularly well suited for year-round use, including winter snow, muddy spring trails, wet fall conditions, and summer road trips.

The raised perimeter walls create a containment reservoir that helps capture water, mud, snow, dirt, pet accidents, and liquid spills. This design helps reduce cleanup time and protects factory carpeting from long-term damage.

The textured anti-slip surface also helps reduce cargo movement while driving. Combined with WeatherTech's durable construction, this creates a premium cargo management solution for Jeep owners who regularly use their vehicle for work, adventure travel, overlanding, pet transport, and recreational activities.

For Wrangler JL Unlimited owners seeking maximum cargo-area protection while maintaining vehicle value and interior appearance, the WeatherTech 401171SK remains one of the most trusted solutions available.
