What Owners Say
Owners and enthusiasts recognize Supertech SPT Dual Valve Springs as proven components for high-performance builds, with the dual spring design specifically engineered to prevent valve float at elevated RPM ranges beyond 10,500+ and support power levels exceeding 800 horsepower. The primary consideration among builders is whether dual springs are necessary for their application, as they add rotating mass compared to lighter beehive alternatives—a trade-off that matters most for extreme builds rather than moderate upgrades. Some users note the springs require appropriate tools for installation, as their higher spring rates demand more compression force than stock components. These springs have established a solid reputation across multiple platforms for serious engine builders pushing RPM and power limits.
