Dual valve springs are designed for high-performance and racing builds that require increased seat and open pressure for superior valve control at elevated RPM.

Supertech valve springs are manufactured from premium Chrome Silicon alloys and heat-treated for fatigue resistance, while the included titanium retainers reduce valvetrain mass to improve control at higher engine speeds.

Features

• High-tensile dual spring construction for increased control
• Titanium retainers reduce mass and increase RPM capability
• Computer-modeled spring profiles for harmonic stability
• Designed to maintain consistent pressures under extreme conditions
• CNC-machined components for exact fit and long-term reliability

Benefits

• Superior valve control for high-lift/high-RPM applications
• Reduced valve float and improved stability at speed
• More consistent performance under sustained load
• Durability proven in high-stress environments
• Optimized for performance street and track builds
