Protect the cargo area of your 2021–2023 GMC Yukon XL or Yukon Denali XL with the WeatherTech SeatBack Cargo Liner HP with Bumper Protector, Part 401466IMSK. Designed for coverage behind the second-row seating, this custom-fit liner safeguards the cargo floor and the backs of the rear seats when they are upright or folded down. Its durable, rubber-like thermoplastic elastomer construction helps defend against water, mud, grass, dirt, pet hair, spilled groceries, sports equipment, and other everyday cargo-area messes. The integrated bumper protector helps shield the vehicle during loading and unloading.
The patent-pending expandable accordion hinge allows the rear seats to move into the full-down position while maintaining continuous protection across the cargo area and seat backs. Water-retention ribbing helps contain moisture and spills, reducing the risk of messes spreading throughout the vehicle. Non-slip nibs on the underside and hook fasteners help hold the liner securely in place, whether it is installed on the cargo floor or extended over the seat backs. The one-piece design also makes installation, removal, and cleaning straightforward.
The WeatherTech SeatBack Cargo Liner HP features a trimmable outline that can accommodate ISOFIX child-seat attachments while helping the liner remain properly positioned. Its flexible material is engineered to withstand extreme weather conditions without breaking down and is 100% recyclable. The liner contains no latex, PVC, cadmium, or lead, making it a practical choice for families, pet owners, outdoor enthusiasts, and anyone who regularly uses the cargo area. Custom-fit coverage, durable construction, and a clean black finish provide dependable protection while complementing the interior of your vehicle.
