Shopper Award

For almost 50 years we have been manufacturing hard core racing components for various types of engines in wide range of categories. Our R&D department continue to innovate and produce products that keep up with today's fast growing automotive market.

Our technology allows us to provide the highest level of performance and reliability for our customers. Our association with many of the industry's leading head manufacters has given us the opportunity to implement these race proven high quality designs for all categories of racing.

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.
