Small Diameter “Max-Life” Dual w/Damper Valve Spring
Better HFDTM (High Frequency Dynamics) Than Any Other Low-Mass Design
Designed for maximum endurance in sustained high RPM dirt late model applications employing super lightweight valve components: (7mm diameter intake and 5/16” diameter exhaust valves) along with titanium valve locks, lightweight “tool steel” retainers and large dia/heavy wall pushrods. Coupled with the above components, the natural frequency separation of the Centrifugally Dampened™ #1410ML yields superior valve control over any current valve spring designs.
