COMP Cams Beehive Valve Springs are revolutionizing performance street/strip applications. These valve springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and the retainer. For street/strip applications, these valve springs are the best choice possible. Because of the unique Beehive design, the valve train can handle more rpm and more aggressive cam profiles for occasional bracket racing but still retain durability for street driving.
