About This Product
If you are building a high-performance 1936 to 1947 Knucklehead, this Kibblewhite valve spring kit is a necessary upgrade. Designed for racing and high-lift builds, this kit helps reduce total valve train mass while providing the stability needed for cams up to .480-inch lift. The springs are wound from premium chrome silicone wire, then shot-peened and heat-treated for a long fatigue life. This comprehensive kit is sold as a kit and includes the springs, steel upper collars, lower collars, and valve keys. Note that these must be used with KPMI valve guides, and stock-dimension guides will require shortening and machining according to the included instructions.
Manufacturer part number: 20-20170.
