Ferrea Single Beehive Ovate PAC Alloy Valve Spring | 1994-1998 Toyota Supra (S2021)

1994-1998 Toyota Supra Beehive Ovate PAC Alloy Valve Spring by Ferrea

Ferrea‚¬™s PAC Alloy Beehive Valve Spring series are available for domestic performance street/strip and racing applications. These single Beehive form valve springs are designed and optimized to reduce valvetrain harmonics, provide greater spring stability, and reduce spring and retainer masses for increase performance and durability in today‚¬™s harsh racing engines.

PAC Alloy Beehive Valve Springs are developed from premium grade super-clean PAC Alloy material designed for racing applications. These valve springs are crafted using the latest technology in manufacturing and processing techniques through the use of state-of-the-art equipment unmatched throughout the industry. Our springs are progressively coiled with tighter tolerances, heat treated, stress relieved, and multistage shot peen for extended life and durability. Strict quality control procedures and cycle testing ensures consistency from batch-to-batch.

Ferrea has expanded their valve spring line offering PAC Alloy Beehive Ovate (Oval/Multi-Radius) wire shape designed to withstand aggressive endurance requirements. Key advantages in using an ovate wire shape are better heat dissipation for longer life, and valvetrain stresses are more effectively distributed over the entire wire shape extending spring life and enabling more horsepower. They have the highest level of fatigue resistance available, while minimizing load loss for today‚¬™s aggressive valvetrain combinations.

PAC Racing develops beehive springs with aid of RPD (Rapid Prototype Development) technique to ensure that the engine runs as expected. Numerous spring designs are evaluated and tested before the final spring shape is determined.

Please Note: This Spring requires Ferrea Titanium Retainer # E12029 and Factory Spring Shims.
