Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicon steel. Their springs are heat-treated and stress relieved, which dramatically increases the spring’s life. The valve springs provide the stability needed for high lift, high rpm racing engines while minimizing the load loss for today’s aggressive valvetrain combinations.
