2003-2008 Nissan 350Z Single Valve Springs by Ferrea

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 springs 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 todays aggressive valvetrain combinations.

Please Note: This Spring to be used with Factory Valves with recess tip and Ferrea Titanium Retainer # E11060 AND Factory supplied Spring Seat Locator
