The Precision Inner Fender Seal Kit (Left & Right, FSK 4440 70) provides a complete pair of inner fender seals designed for 1970 model-year vehicles using the FSK 4440 specification. These seals restore the factory gap and protection between the inner wheelhouse and outer fender, keeping water, road debris, and dust out of the inner fender area to reduce corrosion and interior damage. Molded from weather-resistant EPDM rubber for long-term flexibility and a consistent seal, the kit delivers OEM-style fit and durable performance. Ideal for restoration projects and routine maintenance, this kit simplifies replacement and helps preserve vehicle value.
