The .937 Dia. Inner Valve Springs with .697 ID (SKU COM974-16) are precision-engineered components designed for serious engine builders and performance enthusiasts who demand reliable valve train control. These inner valve springs are essential for maintaining proper valve seating, preventing valve float at high RPM, and ensuring consistent engine performance across demanding driving conditions.

Manufactured to exacting tolerances, these inner valve springs feature a .937-inch outer diameter and a .697-inch inner diameter, precisely matching OEM and aftermarket valvetrain geometry. They work in tandem with outer springs to control valve velocity, reduce wear on valve seats and guides, and provide the dual-spring system necessary for stable operation at elevated RPM levels. The spring rate and preload characteristics are calibrated to complement popular performance camshaft profiles, preventing valve bounce and maintaining crisp throttle response.

These inner valve springs are ideal for engine builders tackling cam upgrades, top-end rebuilds, or complete engine assembly on street and competition platforms. They pair effectively with COMP Cams outer springs and valve components for a cohesive valvetrain package that handles moderate to aggressive cam profiles, ensuring durability and reliability in performance applications.
