• Designed for high-revving engines above 6000 RPM
• Made from silicone-treated steel for durability
• Prevents valve float at high RPM
• Requires machining of valve spring boss for installation

High-performance engines that reach 6500 RPM or more require added protection to prevent valve float, which can severely affect engine performance. The Dual Hi-Rev Valve Springs from CB are engineered specifically for these high-revving engines, ensuring valve stability and optimal performance even under extreme driving conditions.

Manufactured from silicone-treated steel, these valve springs are built to withstand the intense stress of high-performance driving. They provide the necessary strength to keep your engine running smoothly at higher RPMs. However, it is important to machine the cylinder head valve spring boss before installation to ensure proper fitment and function of the dual valve springs.
