About This Product
For those rebuilding a classic 1948–1965 Panhead, this Kibblewhite valve spring kit is an excellent choice for maintaining stock specifications. These springs are wound from high-quality chrome silicone wire, then shot-peened and heat-treated to ensure a long fatigue life. The kit is rated for up to .415-inch valve lift and provides a steady 129 lbs of seat pressure, making it ideal for OEM-style rebuilds. This complete kit includes the springs, upper and lower steel collars, and valve keys. It is a reliable way to restore the valvetrain performance of your vintage Harley-Davidson while benefiting from modern manufacturing materials.
Manufacturer part number: 20-20430.
