About This Product
This Athena engine seal is designed for the early era of Harley-Davidson performance, fitting 1952–1956 K and KH models as well as 1957–1971 XR and Ironhead Sportsters. Replacing OEM 63858-49, it is a critical component for any mechanic or owner looking to keep their vintage machine in top running condition. These older engines demand precise sealing to maintain performance, and Athena provides a reliable solution that stands up to the heat and vibration of an Ironhead motor. Whether you are performing a routine service or a complete engine overhaul, this gasket ensures a professional-grade seal for your classic Sportster.
