This part cross-references Ford F81Z-2520758-AA for the same application.

Common Problems It Can Address

• Air leakage around the lower door opening
• Water intrusion at the front lower door seal area
• Wind noise entering the cabin
• Worn, cracked, or flattened original door weatherstrip
• Reduced sealing performance from age and exposure

Installation Notes and Tips

Verify the vehicle year, model, and front lower position before ordering. Clean the mounting surface thoroughly before installing the new seal so the clips seat properly and the seal can align evenly along the door opening. Compare the removed seal to the new part number FD0818503 to confirm length, width, and attachment style match the original application.
