Valve Springs, Retainers are crucial components in an engine's valvetrain system. They work together to control valve motion by maintaining constant pressure between the camshaft and the valves. Upgrading valve springs and retainers to high-performance parts is essential for engines with aggressive camshafts, high RPM applications, and increased valve spring pressures. When choosing valve springs and retainers, consider factors like spring rate, material composition, and compatibility with other valvetrain components.
