What is the purpose of the damper in these valve springs?

The damper integrated into these dual valve springs is designed to control harmonics within the spring. This helps to prevent excessive oscillation and resonance, which can lead to valve float and reduced performance, especially at high engine speeds.

Are these springs suitable for a stock engine rebuild?

These valve springs are specifically engineered for high-performance engine builds and aggressive camshaft profiles. While they can be used in some modified stock applications, they are typically intended for engines with upgraded valvetrain components and higher RPM capabilities.

What is included in this set of valve springs?

This set includes 16 dual valve springs, which is the standard quantity needed for a V8 engine. It is important to verify your specific engine's requirements to ensure you have the correct number of springs.
