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 single valve springs feature flat internal damping coils to prevent spring surge at high revs, maintaining proper spring pressure at critical load levels. 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.
