About This Product
This Kibblewhite valve spring kit is designed specifically for 1957 to early 1983 Sportster models. It is an ideal choice for OEM-style rebuilds where maintaining stock specifications is a priority while still upgrading the component quality. The kit includes springs, steel upper and lower collars, and valve keys. These springs are made from high-quality chrome silicone wire that has been shot-peened and heat-treated for a long service life. Designed for a maximum valve lift of .400 inches, they provide 95 lbs of seat pressure and 330 lbs of open pressure. By reducing total valvetrain mass, this kit helps improve engine efficiency and reliability. This complete kit is sold as a set.
Manufacturer part number: 20-20440.
