1.490 Valve Springs

The 1.490 Valve Springs from ISKY CAMS are designed for automotive enthusiasts and engine builders who require reliable valve control in high-RPM applications. These springs play a crucial role in closing intake and exhaust valves with the necessary timing and force, making them essential for performance engine builds, whether for street use or track racing.

Manufactured from premium-grade alloy steel, these valve springs utilize precision winding techniques to ensure consistent load rates and minimal variance between individual springs. The 1.490 measurement indicates the outer coil diameter, which is a standard specification that affects spring rate and pressure characteristics, crucial for compatibility with various camshaft profiles.

Engine builders working on small-block Chevrolet, Ford, Mopar, or Japanese platforms will find these valve springs particularly beneficial. They are designed to work effectively with quality valve seats, retainers, and locks, ensuring a valve train that can maintain tight tolerances under extreme stress, whether in naturally aspirated or forced induction setups.
