This FKM rubber valve stem seal provides a precise, high-performance barrier to prevent engine oil from entering the combustion chamber through the valve guides. The premium FKM material is engineered for exceptional heat resistance and chemical stability, ensuring the seal remains pliable and effective under the extreme temperatures of the cylinder head. This direct-fit component helps reduce oil consumption and exhaust smoke while protecting the valves from carbon buildup, supporting overall engine efficiency and longevity.

This valve stem seal fits 1999-2017 Harley Davidson Dyna, Softail, Touring, and Trike models equipped with the Twin Cam engine.
