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

The damper is integrated into the dual spring design to help control harmonics and prevent valve float. This is especially important in high-RPM or high-stress engine conditions to maintain consistent valve operation.

Are these valve springs suitable for stock engines?

These valve springs are specifically designed for high-performance engine builds and are generally not recommended for stock applications. They are intended to work with performance camshafts and higher engine speeds where stock springs may not suffice.

What is included in this set of valve springs?

This set includes 16 dual valve springs with dampers, which is typically enough for a standard V8 engine. It's always a good idea to confirm your specific engine's requirements before purchasing.
