Ferrea Valve Spring-SB S 1290 105/293 LS1-LT1 BH
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. These
springs are manufactured with state-of-the-art equipment. Our springs are heat-treated and stress relieved, which
dramatically increases the spring’s life. Strict quality control procedures and cycle testing ensures consistency from
batch to batch. Ferrea valve springs provide the stability needed for high lift, high rpm racing engines, while
minimizing the load loss for today’s aggressive valvetrain combinations.
We expanded our Springs offering to include many new designs and applications. Our goal is to provide the best
possible valve-train combinations for all racing environments from circle track, drag racing, motorcycle racing and
offshore marine racing.
