Dual Valve Springs With Damper- 1.519 Dia.

The Dual Valve Springs With Damper - 1.519 Dia. from COMP CAMS is engineered for serious engine builders and performance enthusiasts looking to maximize valve control at high RPMs. These dual valve springs are essential for any forced-induction, naturally-aspirated, or radical cam swap project where valve float and spring surge become critical concerns. Whether you're building a street strip machine or a dedicated race engine, proper valve spring selection directly impacts power delivery, reliability, and longevity of your entire valvetrain assembly.

COMP CAMS' Dual Valve Springs With Damper feature a 1.519-inch diameter design that provides the precise spring rate and damping characteristics needed to control aggressive valvetrain dynamics. The integrated damper within this assembly eliminates harmonic oscillation that occurs when valve springs vibrate at high frequencies, reducing the risk of valve float and spring breakage under sustained high-RPM operation. The dual-spring configuration offers a progressive rate characteristic, meaning initial closure is controlled by the inner spring while the outer spring engages to provide additional support as valve acceleration increases, creating a stable, predictable opening and closing event throughout the RPM band.

This valve spring assembly is ideal for builders working with performance cam profiles, turbo/supercharged applications, and any engine modification exceeding stock valve velocity parameters. Installation requires proper valve spring seat pressure verification using a spring tester to ensure optimal performance and prevent premature wear on rocker arms and pushrods. Compatibility depends on your specific cylinder head design and the outer diameter of your valve spring retainer; always cross-reference these dimensions with your head manufacturer's specifications before ordering to ensure correct fitment and reliable operation.
