What is the primary benefit of using dual valve springs with a damper?

Dual valve springs offer increased stability and control over a wider range of engine speeds. The integrated damper helps to suppress harmonic vibrations within the spring, reducing the risk of valve float and ensuring more consistent valve operation, especially in high-RPM performance engines.

What material are these Ferrea valve springs made from?

These valve springs are constructed from high-tensile strength steel. This material is chosen for its ability to withstand the significant stresses, heat, and constant cycling that performance engines experience.

Are retainers and valve seals included with this set of valve springs?

This product listing is for a set of 16 dual valve springs with dampers. It does not explicitly state that retainers or valve seals are included. It is recommended to check the manufacturer's detailed product information or contact customer support for a complete list of included components.

Product Details

If you're building a high-performance engine, you need valve springs that can keep up. This set of 16 dual valve springs from Ferrea, part number S11014, is designed to handle the demands of aggressive camshaft profiles and high RPM operation. They feature a dual spring design with an integrated damper to control harmonics and prevent valve float, ensuring reliable performance under stress.

Ferrea is well-known for its commitment to quality in engine components. These springs are constructed from high-tensile strength steel, chosen for its ability to withstand the constant cycling and heat generated in performance applications. The specific dimensions, with an inner diameter ranging from 0.74 to 1.145 inches and an outer diameter from 1.04 to 1.56 inches, are critical for matching with specific camshafts and cylinder heads. The included damper plays a crucial role in reducing spring surge and maintaining consistent valve control, especially at higher engine speeds where stock springs might falter.

This set includes everything needed for a complete engine build, with 16 springs to cover all cylinders. When installing performance valve springs, it's important to ensure your camshaft and retainers are also suited for the increased spring pressures to avoid premature wear or component failure. Always refer to the manufacturer's installation guidelines for proper setup and compatibility checks.
