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.

The design and processes on these dual valve springs are optimized to reduce valvetrain harmonics and provide greater stability on high horsepower applications. We use high grade premium super-clean PAC alloy materials and maintain tight tolerances for those unique aftermarket cylinder heads.

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.
