What is the purpose of a dual valve spring with a damper?

A dual valve spring offers two different spring rates, helping to control valve float at high RPMs and provide better stability. The damper is an internal coil that reduces harmonic vibrations within the spring, further enhancing valvetrain stability and preventing wear.

What materials are these Ferrea valve springs made from?

These valve springs are constructed from a strong, durable alloy specifically chosen by Ferrea for high-performance engine applications. This material is selected to withstand the intense forces and heat generated in demanding engine builds.

What other components are typically needed when installing these valve springs?

When installing performance valve springs like these, you'll generally need compatible valve retainers, valve locks (keepers), and potentially upgraded camshafts and pushrods depending on your engine build. Always refer to your engine builder's specifications for a complete list of required components.

About this part

Product Details

This is a set of 16 Ferrea dual valve springs, designed for high-performance engine builds where precise valve control is critical. These springs feature a dual-rate design, meaning they offer different spring pressures at different points in their travel. This setup helps to control valve float at higher RPMs and provides a more stable valvetrain, especially when you're pushing your engine hard. The integrated damper works to reduce harmonic vibrations within the spring, further improving stability and preventing premature wear.

Ferrea is known for using high-grade materials, and these springs are no exception. They are constructed from a strong, durable alloy that can withstand the intense forces and heat generated in a performance engine. The specific dimensions, with an outer diameter ranging from 1.570 inches down to 1.025 inches and an inner diameter from 1.135 inches down to 0.74 inches, are engineered to work with specific camshaft profiles and cylinder head configurations. This dual-rate design with a damper is a smart way to achieve improved valve control without sacrificing too much low-end response, making them a solid choice for serious engine builds.

When installing these springs, it's important to ensure your camshaft and retainers are compatible. Ferrea designs these for demanding applications, so proper installation according to your engine builder's specifications is key to unlocking their full potential. This set includes everything you need for a complete engine build, providing a well-built valvetrain component that contributes to overall engine reliability and performance under stress.
