Description

This KPMI® O.E.M. replacement kit is designed to give stock pressures and work with stock cam profiles. This kit is manufactured to original O.E.M. specifications using premium modern materials, design protocols and manufacturing techniques. All of the components in this O.E.M. style spring kit are the high quality parts you expect from KPMI®. Valve springs are wound from Super Clean chrome silicon valve spring wire that has been heat treated and shot peened. The retainers, keepers, and bases are modeled using FEA analysis to maximize mechanical strength. Components are interchangeable with O.E.M. components unless otherwise noted.
