The Sifton Nitrate Valve and Spring Kit is a complete valvetrain replacement package for select Harley-Davidson Shovelhead FL models. Designed for dependable service and straightforward installation, this kit includes two intake valves and two exhaust valves with a durable nitrate finish, along with a complete valve spring set, keepers, and upper and lower collars. The components are matched to support consistent valve operation in properly maintained Shovelhead engines.
This kit is a practical choice for engine rebuilds, cylinder head service, and valvetrain restoration projects where replacing related components together can help simplify installation. The nitrate-finished valves provide a hard, wear-resistant surface, while the included springs, keepers, and collars help complete the valve assembly without requiring separate sourcing for each primary component. Verify engine specifications and existing valvetrain components before installation to ensure proper compatibility and setup.
The Sifton valve and spring kit fits 1966 through 1975 Harley-Davidson FL models, including FL applications from 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, and 1975. Professional installation or service by a qualified motorcycle technician is recommended, including inspection of valve guides, seats, springs, retainers, and related hardware before assembly. Follow the motorcycle manufacturer’s service procedures for valve adjustment, spring installation, and final engine inspection.
