1.437 Dia. Dual Valve Springs- .695 ID.

The COMP CAMS 1.437 Dia. Dual Valve Springs with .695 ID are precision-engineered components designed for high-performance engine applications where reliable valve control and consistent lift are critical. These dual valve springs represent the performance standard for racing engines, street performance builds, and competition powerplants where factory spring rates cannot deliver the rigorous demands of aggressive cam profiles. Built by COMP CAMS—a trusted leader in valvetrain technology—these springs provide the damping characteristics and load stability required when stock springs fail under modified engine conditions.

The dual spring design combines an outer primary spring with an inner auxiliary spring to eliminate valve float, reduce harmonic resonance, and maintain precise closure rates across the entire RPM range. With a 322 lb/in spring rate and a 1.150 inch coil bind specification, this assembly delivers controlled preload while preventing coil stacking at maximum lift. The 1.437 inch outer diameter and .695 inch inner diameter bore ensure compatibility with standard valve spring seats found on most American V8 and small-block platforms. The compact 4.05-inch length simplifies installation while maintaining optimal spring geometry for both intake and exhaust valve applications.

These 1.437 Dia. Dual Valve Springs are ideal for engine builders, race teams, and performance enthusiasts upgrading camshaft packages beyond original equipment specifications. Whether you're installing a radical hydraulic roller cam, a solid roller profile, or a street/strip combination grind, this spring set delivers the valve control necessary to maximize lift and duration without sacrificing reliability. Installation requires proper seat and guide inspection, and springs should be checked for free length before assembly to ensure correct preload and installed height. Each unit ships individually, allowing builders to purchase the exact quantity needed for multi-cylinder engine builds.
