1996-1998 Toyota MR2 Dual 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 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.

Please Note: This Spring requires Ferrea Titanium Retainer # E11123 and Ferrea Spring Seat Locators # SL1134. Discard OEM Factory Spring Seat Locator
