Review MANLEY Engine Valve Spring

The Manley 221449P-16 Engine Valve Spring is a high-performance aftermarket valve spring designed to deliver superior reliability and durability for racing and high-performance applications. This valve spring is specifically engineered for use in pushrod engines with a 16mm (0.630 inches) intake valve diameter.

The Manley valve spring is manufactured from chrome silicon alloy material, which provides excellent fatigue strength, resilience, and the ability to withstand the extreme forces encountered during high RPM operation. The spring's open-ended design ensures optimal valve control and reduces the risk of valve bounce, ensuring consistent engine performance.

This valve spring features a dual-spring design, with a tall primary spring and a shorter secondary spring, providing a stable valve train and improved valve control under high engine loads. The spring's compression height is 11.5mm (0.453 inches), and the installed height is 13.5mm (0.531 inches), making it suitable for use in performance engines with increased valve lift.

The Manley 221449P-16 Engine Valve Spring comes with a set of titanium retainers, which offer superior strength, durability, and weight reduction compared to traditional steel retainers. The retainers are also designed to provide a positive seal against the valve stem, reducing the risk of valve float and ensuring consistent valve action.

This valve spring is engineered to meet the demanding requirements of racing and high-performance applications and is suitable for use in both naturally aspirated and forced-induction engines. It is recommended for use in pushrod engines with high RPM operation, large valve sizes, and increased valve lift, making it an excellent choice for high-performance applications.

In summary, the Manley 221449P-16 Engine Valve Spring is a high-performance aftermarket valve spring designed to deliver superior reliability, durability, and improved valve control for racing and high-performance applications. Its open-ended design, dual-spring configuration, and use of chrome silicon alloy material and titanium retainers make it an excellent choice for high RPM, high-lift, and high-load applications.
