1.225in to 1.570in Diameter 1.153/1.56 OD 0.82/1.155 ID Dual Valve Spring - Set by Ferrea
Harmonics or high frequency fatigue is present in all racing engines and will usually destroy the valvetrain if not controlled. Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear.
Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicon steel. Our springs are heat-treated and stress relieved, which dramatically increases the spring's life. Our valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today's aggressive valvetrain combinations.
