Features
Lightweight Dual Drag Race Valve Springs
Features
- Higher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential
- Dual spring design reduces friction, which generates less heat and translates into greatly reduced load loss
- Extensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective
- Smaller diameter, lightweight dual design allows engine to rev higher with improved valve train control
- Accepts smaller, lighter retainers which also promotes higher revs
- Ultra clean, high tensile strength chrome silicon material
- Super Finished multi-step surface enhancement significantly improves fatigue strength
- Ideal loads for multiple applications with minimal load loss
