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

The damper is designed to help control spring harmonics and prevent valve float, especially at high engine speeds. This helps ensure consistent valve train operation and reliability under demanding conditions.

Are these springs suitable for stock engines?

These dual valve springs with dampers are specifically built for high-performance engine builds. They offer increased seat and open pressures that may be excessive for a stock engine's valve train.

What information do I need to confirm these springs will work with my camshaft?

You'll need to compare the spring's specifications, such as installed height, seat pressure, and open pressure, against the requirements listed by your camshaft manufacturer. This ensures proper valve train geometry and function.

Product Details

This is a set of 16 dual valve springs from Ferrea, part number S11012. These springs are built for high-performance engine builds where precise valve control is critical. They feature a dual spring design with an integrated damper to help control harmonics and prevent valve float at high RPMs. The springs have an inner diameter ranging from 0.74 to 1.145 inches and an outer diameter from 1.04 to 1.56 inches, with a free height that allows for a wide range of installed heights.

Ferrea is known for making well-built engine components, and these valve springs are no exception. They are constructed from strong materials designed to withstand the intense pressures and temperatures found in performance engines. The dual spring setup offers increased seat pressure and open pressure compared to single springs, which is essential for keeping the valves sealed tightly against the cylinder head during aggressive camshaft profiles and high engine speeds. The included damper is a key feature for preventing spring surge and ensuring consistent valve train operation, especially when you're pushing your engine hard.

When you're building a performance engine, the valve springs are a crucial component that needs to be up to the task. This set of 16 Ferrea dual springs with dampers is designed to provide the reliability and performance needed for demanding applications. Make sure to consult your engine build specifications and camshaft requirements to confirm these springs are the right match for your specific setup.
