This professional-grade valve stem seal provides a precision-engineered sealing solution for routine valvetrain maintenance and cylinder head rebuilds. Manufactured from premium FKM rubber (Viton), this robust seal is engineered to withstand extreme combustion temperatures, aggressive engine oils, and constant friction without degrading. It delivers an exact, reliable fit to regulate oil flow down the valve guide, prevent oil consumption, and maintain optimal engine compression.

This fits 1984-2025 Harley-Davidson Evolution, Twin Cam, and Milwaukee-Eight Dyna, Softail, Touring, Sportster, and Trike models.
