COMP Cams Beehive 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.
