SET OF SIXTEEN

For Over 45 Years Ferrea has been manufacturing hard core racing engine valves and components for various types of engines in a wide range of categories worldwide. Ferrea uses the latest technological advances gained through the development of engine valve programs for Formula 1, Indy Car, NASCAR, Sprint Car, Drag and Road racing teams. This technology allows Ferrea to provide the highest level of performance and reliability for their customers.

Details of this specific product are as follows:

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.
