COMP Cams Race Extreme Dual Valve Spring OD Installed Height

COMP Cams Race Extreme Dual Valve Springs are high-performance engine valve springs built for racing and other demanding valvetrain applications. Each spring assembly pairs an outer and inner spring, which gives the strength and stability needed to control the valve at high RPM and with aggressive camshaft profiles.

Key Features:

• Dual spring design: The nested outer and inner springs make a stronger assembly. It can handle the higher lift found in extreme-stress applications.
• Valvetrain stability: The design helps reduce valve float and control harmonic vibration. It also helps keep spring pressure consistent through the lift cycle.
• Quality materials: COMP Cams makes its dual springs from premium spring wire and tests them extensively. The goal is strength and durability under heavy load.
• Race-focused construction: The springs are for engine builders and racers who need dependable valve control in high-RPM, high-lift engines.
• Matched components: COMP Cams offers compatible retainers, spring cups, seats and locks, so you can build a complete valve spring system.

Spring pressure should be matched to your camshaft, so choose the variant that fits your cam's recommended specifications. COMP Cams is a well-known name in camshafts and valvetrain components. These springs are a good choice for engine builders who want durable, consistent performance in competition engines.
