The PAC Racing HR Series Valve Spring is designed for the performance enthusiast who needs reliable valve control in high-stress environments. Featuring a dual spring and damper configuration, this spring is built to handle the demands of aggressive camshafts while maintaining consistent spring pressure. With a spring rate of 469 lb/in, it provides the necessary force to prevent valve float at high RPMs, ensuring your engine breathes efficiently throughout the power band.
The HR Series is a staple in the racing community, known for its ability to resist fatigue and maintain pressure over long service intervals. The inclusion of an internal damper is a key feature, as it effectively manages spring surge and harmonic resonance that can lead to premature failure in lesser springs. Whether you are running a street-strip vehicle or a dedicated track car, these springs provide the stability needed to push your engine to its limits. When you choose PAC Racing, you are choosing industry-leading technology that has been proven on the track. Enhance your engine's reliability and performance with these premium springs from GGCRACING.
