昀椀tment promotes longer component life and
optimizes performance of the entire valve train.
Springs
Advanced spring design
Springs are engineered for each speci昀椀c
application using proprietary advanced spring
design, simulation, and analysis software.
Engineers pay special attention to cam and spring
harmonics, stress, mass, and operating rpm.
Premium grade, super clean
ground chrome silicon wire
X-Rayed at regular intervals to check for
inclusions, heat treated, and shot peened.
Insuring maximum spring life.
Heat treated steel retainers
Proprietary heat treatment process
Creates a hard outer shell with a non-brittle core,
resisting wear and maximizing toughness.
