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 springs life.

Ferrea valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for todays aggressive valvetrain combinations. Ferreas wide range of retainers are available for Domestic, Sport Compact and Motorcycle markets. We currently offer four different types of retainers to choose from: Titanium, Lightweight Tool Steel, Steel and Aluminum Magnesium retainers, all of which are CNC machined to perfection and offer superior strength and stability.
