WeatherTech 421865SK Grey Cargo Liner with Bumper Protector

The WeatherTech 421865SK is a vehicle-specific Grey Cargo Liner and Bumper Protector combo engineered to provide complete rear cargo area and bumper protection for the 2026 Hyundai Ioniq 9. Each liner is computer-designed for a precise, custom fit — delivering far superior coverage compared to universal cargo mats.

The cargo liner is constructed from WeatherTech's proprietary custom-blended TPO (thermopolyolefin) material that is wear resistant while remaining flexible under temperature extremes, ensuring year-round performance. A raised perimeter lip (typically 1.25") contains spills, dirt, grease, and debris within the liner, keeping them away from factory carpeting and upholstery. The textured, non-slip surface finish helps prevent cargo from shifting during normal driving.

This kit pairs the cargo liner with WeatherTech's Bumper Protector — a highly durable vinyl fabric cover that snaps onto the cargo liner via stainless, rust-resistant snaps. Simply unroll the Bumper Protector over the rear bumper during loading and unloading to shield the paint surface from dings, scratches, and scuffs. When not in use, the protector rolls up and secures neatly with integrated hook-and-loop straps. Note: Cargo Liners ordered with Bumper Protectors come with snaps pre-installed; the Bumper Protector cannot be added to a standard Cargo Liner after purchase.
