Howards Cams Pro-Alloy Dual Valve Springs are specially developed from low stress, high endurance alloy. The Pro-Alloy valve springs feature a low fatigue rate when compared to other roller springs. These valve springs have been cycle tested to 12 million cycles with no breakage. Each spring is coiled using the most advanced CNC winders available. The springs are then parallel ground, stress relieved, shot-peened and heat-treated to Howards Cams' precise standards.
