1.465 Dual Valve Spring Kit w/Damper

The 1.465 Dual Valve Spring Kit w/Damper from HOWARDS RACING COMPONENTS is a precision-engineered valve spring assembly designed for high-performance racing engines that demand reliable valve control and extended rpm capability. Built for serious engine builders and race teams, this dual-spring configuration provides the stability needed in competitive applications where valve float prevention and consistent lift characteristics are critical.

This valve spring kit features a dual-spring design with a verified spring rate of 425 lb/in and a 0.950 inch coil bind specification, delivering the pressure curve necessary to control valve motion across the entire engine speed range. The 1.465 inch outside diameter allows for compact installation in modern cylinder heads while maintaining adequate spring seat contact. The kit includes chromoly steel retainers and locks, chosen for their superior strength-to-weight ratio and resistance to fatigue failure common in racing environments.

This kit is ideal for engine builders working with aluminum or iron cylinder heads in small-block and mid-displacement applications. The integrated damper minimizes harmonic vibration in the spring stack, reducing the risk of spring surge that can lead to premature wear or catastrophic failure during maximum effort runs. Whether you're assembling a circle-track engine, bracket racer, or street performance build, this kit addresses the core requirement of maintaining valve timing integrity under sustained high-load conditions.
