WeatherTech 421731IM SeatBack Cargo Liner HP Grey with 3rd Row Seating

The WeatherTech 421731IM SeatBack Cargo Liner HP delivers complete, custom-fit cargo area protection for Tahoe and Yukon models equipped with 3rd row seating — in a sleek High-Performance Grey finish. Unlike standard cargo mats that only cover the floor, this one-piece liner shields both the cargo floor and the backs of your rear seats, giving you uninterrupted protection whether your seats are up or folded down.

At the heart of this liner is a patent-pending expandable accordion hinge, which flexes with your rear seats as they move between their upright and full-down positions — eliminating gaps, exposed carpet, and seat back damage. A laser-measured, custom-fit design ensures a precise, factory-like fit with no trimming required.

Key Features:

• One-piece construction covers the cargo floor and rear seat backs simultaneously
• Accordion hinge maintains full coverage when seats are folded flat
• Water retention ribbing system traps spills and prevents moisture from seeping into carpet
• Non-slip nibs and hook-and-loop fasteners keep the liner securely anchored on both the floor and seat backs
• Made from heavy-duty thermoplastic elastomer (TPE) — flexible in extreme temperatures and 100% recyclable
• Free of latex, PVCs, cadmium, and lead
• Trimmable outline accommodates ISOFIX child car seat attachments
• Designed and manufactured in the USA
• Easy tool-free installation and removal
• Compatible with WeatherTech CargoTech cargo containment system (sold separately)

Perfect for hauling pets, sports equipment, groceries, strollers, tools, or anything else that can create a mess. When it's time to clean, simply remove the liner and rinse away dirt and debris. WeatherTech TechCare Cleaner (sold separately) handles tougher scuffs and spills.
