What is the primary function of these valve springs?

These valve springs are designed to close the engine's valves quickly and reliably after they are opened by the camshaft. For performance applications, they are built to handle higher lift camshafts and increased engine speeds without losing tension or causing valve float.

What does 'SPRING-1.550' refer to?

The '1.550' in the part name refers to the outer diameter of the valve spring in inches. This measurement is critical for ensuring the spring fits correctly within your cylinder heads and works with the appropriate retainers.

Are these valve springs suitable for stock engines?

These valve springs are intended for performance engine builds and may not be necessary or optimal for a stock application. They are designed to handle higher stresses associated with modified camshafts and increased RPMs.
