Valve springs compress and rebound hundreds of times a second. Make sure your next set of valve springs are built to last—and built to win! Trick Flow® by PAC Racing dual valve springs are specifically designed for cams with aggressive profiles, and are available with damper coils for extra spring surge prevention. PAC springs are CNC coiled from high tensile-strength, extra-durable Pacaloy chrome-silicon steel and double shot-peened beyond Aerospace Material Specifications (AMS) reliability standards.
