The PAC Racing HR Series Valve Spring is engineered for high-performance engines that require superior valve control. This dual-spring design with an integrated damper provides the necessary spring rate to handle aggressive camshaft profiles while effectively managing harmonics that can lead to valve float at high RPMs.
When you push your engine to the limit, your valvetrain is the first line of defense. The HR series springs are manufactured using premium materials to ensure consistent pressure and long service life, even under extreme heat and stress. The dual-spring configuration offers a safety net; should the outer spring experience fatigue, the inner spring helps maintain control, preventing catastrophic engine damage. Whether you are building a naturally aspirated powerhouse or a forced induction engine, these springs provide the reliability you need. Explore the full range of performance springs at GGCRACING.
