1.460 Dia. Dual Valve Springs- .700 ID.

The 1.460 Dia. Dual Valve Springs with .700 ID from COMP CAMS represent a critical upgrade for serious engine builders and high-performance mechanics looking to maximize valve control and RPM capability. These dual valve springs are engineered for applications demanding superior spring rate stability and consistent valve seating across aggressive cam profiles. Whether you're building a street performance engine, a weekend track car, or a competition-grade powerplant, dual valve springs provide the mechanical advantage needed to keep pace with modern, aggressive camshaft timing events.

Dual spring assemblies work by combining an outer and inner spring with different rates, allowing engineers to achieve a higher installed seat pressure while minimizing coil bind and resonance issues that plague single-spring designs. The 1.460-inch outer diameter and .700-inch inner diameter configuration delivers the precise spring geometry COMP CAMS is known for, ensuring consistent load curves and rapid valve return without chatter or float at peak RPM. This dual-spring design reduces harmonic distortion during valve events, extends component lifespan, and improves overall valvetrain reliability—critical when operating at elevated engine speeds where single springs would fatigue prematurely or lose control of valve motion.

These springs are ideal for small-block and mid-size engine platforms that run aftermarket or OEM-aggressive camshafts, particularly in street-strip and drag racing applications where valve float cannot be tolerated. Installation requires proper valve spring seat height measurement and selection of compatible retainers and keepers; most seasoned mechanics pair these springs with COMP CAMS roller rocker arms and precision-ground cam shafts for a complete valvetrain package. Verify your engine block's valve spring pocket dimensions and consult your cam manufacturer's spring rate recommendations before ordering to ensure optimal performance and longevity.
