Ferrea 330lbs Rate Inch Dual Valve Spring | 1994-1998 Toyota Supra (S10109) Ferrea Racing

1994-1998 Toyota Supra Dual Valve Springs by Ferree 

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 is 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 ensure consistency from batch to batch. Ferrea Valve Springs provides 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 # E11037 and TWO Ferrea Spring Seat Locators: #SL1001 and #SL1060 (Discard OEM Spring Seat Locator)
