With a 500 lb/in spring rate, these units provide the necessary force to maintain valvetrain integrity in high-lift, high-RPM applications, ensuring your engine remains responsive and powerful.
These springs are crafted to handle the stress of aggressive camshafts and high-speed operation. The dual-spring design, combined with an effective damper, works to suppress harmful harmonics that can cause valve bounce and power loss. By maintaining consistent seat and open pressure, these springs allow your engine to reach its full potential without the risk of valvetrain instability.
