Product Description

The Brian Crower BC1040 Dual Valve Springs are engineered for high-performance applications, specifically designed to handle the demands of high-RPM engines. These springs are wound from premium chrome silicone alloy, ensuring durability and consistent pressure over extended periods of high-speed operation.
