Comp Cams 1.589" Beehive Valve Springs

• Provides better valve control and reduced weight of both the spring and retainer

• Engineered with advanced processing techniques for maximum durability
• Available with maximum lift of .590" to .750"

Street/Strip Valve Springs from COMP Cams 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 retainer. These valve springs are the best choice possible for street/strip applications. Because of their unique design, the valve train can handle higher RPM and more aggressive cam profiles for occasional bracket racing but still retain durability for street driving.
