COMP Cams Race Sportsman Conical Valve Spring OD Installed Height

COMP Cams Race Sportsman Conical Valve Springs are high-performance engine valve springs for street/strip, circle track, road race and drag race valvetrains. They use a conical design that is self-damping. This helps control valve spring surge and resonance at high RPM.

Key Features:

• Conical design: The coil diameter decreases from bottom to top. This reduces active mass and the force applied to the valvetrain.
• Progressive, self-damping action: The springs dampen coil oscillation without the friction, heat or wear of interference-fit damper systems.
• Higher RPM stability: A progressive natural frequency raises the RPM limit and supports more aggressive camshaft profiles.
• Round wire construction: A super-finish surface treatment is designed to improve spring longevity and lift capability.
• Valvetrain efficiency: Reduced mass and lower applied forces can mean longer valvetrain component life and less parasitic horsepower loss.

Conical springs are normally used with matching COMP Cams retainers and spring seats or locators designed for the conical profile. Choose the spring variant that matches your cylinder head, valve lift and camshaft specifications. COMP Cams backs this line with its reputation for performance valvetrain components.
