1957-1979 Harley-Davidson Sportster Main Drive Gear Seal, 4-Speed

This main drive gear seal is constructed with a durable steel housing to provide a secure and stable fit within the transmission assembly. It is engineered to provide a high-performance seal for the main drive gear, preventing transmission lubricant from escaping along the shaft. Designed to endure the thermal demands and mechanical stress of the Ironhead engine, this direct-fit component ensures the long-term reliability of your gearbox and maintains a clean operating environment.

This part fits 1957-1979 Harley Davidson Sportster models including the Sportster 1000, Sportster Standard, Super CH, and Super H.
