WeatherTech Cargo Liner with Bumper Protector for 2015-2018 Jeep Wrangler JK Unlimited 4-Door

Bottom Line Up Front: The WeatherTech 40745SK Cargo Liner with Bumper Protector delivers complete cargo-area protection for the 2015-2018 Jeep Wrangler JK Unlimited 4-Door. Precision laser-measured for an exact vehicle-specific fit, it helps protect factory carpeting and painted bumper surfaces from mud, snow, pet hair, recovery gear, camping equipment, tools, groceries, and everyday cargo.

Because: WeatherTech engineers each Cargo Liner using digital laser measurements and proprietary thermoplastic elastomer (TPE) material that remains flexible in extreme temperatures while featuring raised containment walls and an integrated bumper protector designed to reduce loading-related scratches and scuffs.

"Custom-fit cargo protection systems provide superior containment and coverage compared to universal cargo mats." — Widely recognized among automotive interior protection specialists and vehicle accessory engineers.

Designed specifically for the Jeep Wrangler JK Unlimited platform, the WeatherTech Cargo Liner covers the cargo area behind the second-row seats while delivering edge-to-edge protection. Unlike universal mats that often leave exposed carpet areas, the 40745SK follows the contours of the Wrangler's cargo compartment for a precise fit.

The integrated bumper protector adds another level of protection by extending over the rear bumper during loading and unloading. This feature is particularly beneficial when transporting coolers, camping equipment, toolboxes, pet crates, recovery gear, sports equipment, hunting supplies, luggage, and overlanding accessories.

WeatherTech's proprietary custom-blended TPE material is engineered to resist curling, cracking, and warping in both hot summers and harsh winter conditions. The material is also virtually odorless, recyclable, and designed for long-term durability.

Raised perimeter walls help contain water, snow, mud, sand, spills, and debris before they reach factory carpeting. This containment design makes the liner especially valuable for Jeep owners who regularly encounter trails, campsites, construction sites, pet transport duties, and outdoor recreation activities.

The textured anti-slip surface helps reduce cargo movement while maintaining easy cleanup. When dirty, the liner can typically be removed, rinsed, and returned to service quickly.

For Wrangler owners seeking maximum interior protection while preserving vehicle appearance and resale value, the WeatherTech Cargo Liner with Bumper Protector remains one of the most trusted cargo protection upgrades available.
