Description
Valve spring selection directly impacts your engine’s ability to maintain proper valve control under high RPM conditions, especially in forced induction or heavily modified applications. The Isky 1.625 springs deliver the consistent seat pressure and damping characteristics needed to prevent valve float while minimizing parasitic losses. These are the springs serious builders choose when stock components won’t cut it.
