About This Product
For those performing a stock-style rebuild on a 1936 to 1947 Knucklehead, this Kibblewhite valve spring kit offers modern reliability without needing complex modifications. These springs are manufactured from high-quality chrome silicone wire that has been shot-peened and heat-treated to ensure maximum durability. The kit is designed to handle valve lifts from the stock .348-inch up to a maximum of .415-inch. Sold as a kit, it includes the springs, steel upper collars, lower collars, and valve keys. Because these are stock-style replacements, they can be installed as a direct fit, making them an excellent choice for maintaining the classic performance of your vintage Harley.
Manufacturer part number: 20-20425.
