Isky 1.560 Valve Springs 9975

Valve springs are the unsung foundation of any high-revving engine—they're responsible for controlling rocker arm geometry and preventing float at peak RPM. The Isky 1.560 springs deliver the stiffness and consistency you need to maintain precise valve control under extreme load, whether you're building a street performance engine or a full-race package. With a dual-spring design and damper, these springs handle the harmonic complexities of aggressive cam profiles without sacrificing reliability.
