1.677 Triple Valve Springs

The 1.677 Triple Valve Springs by MANLEY are designed for engine builders and automotive enthusiasts seeking high-RPM reliability and consistent valve control. These springs are ideal for performance engines used in drag racing, road racing, or street applications that require sustained high-lift cam operation.

Engineered to handle aggressive camshaft profiles, these triple valve springs provide the necessary valve seat pressure and damping characteristics to prevent valve float. The design features three nested coil springs that work together to deliver superior frequency isolation and progressive spring rate characteristics, which are essential for maintaining precise timing across the RPM range.

Serious engine builders and motorsports competitors rely on these springs for their ability to reduce harmonic resonance and minimize coil bind risk. The precision manufacturing tolerances typical of MANLEY springs ensure consistent load rates, which is critical for balanced cylinder-to-cylinder valve timing and preventing individual spring failure that could lead to engine damage.
