Designed for the 1967-1972 GM Suburban Truck, these back left and right cargo door seals replace OEM #3909343 and #3909344, ensuring a precise fit. Crafted from high-quality ozone-resistant EPDM rubber, these seals are built to last and maintain their shape over time. They mount directly onto the cargo doors using weatherstrip adhesive (not included), providing a secure and reliable seal. These seals are engineered to keep your climate-controlled air inside while blocking out weather, drafts, and road noise, enhancing your driving comfort. Fitment includes Chevrolet and GMC Suburban models from 1967 to 1972, such as the C10, C20, K10, K20, and their GMC equivalents. With their durable construction and excellent sealing properties, these seals are a practical upgrade for restoring your Suburban’s functionality and comfort.
