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 Triple Sportsman valve springs are designed for bracket drag racing, with higher spring rates for use on ultra high-revving, high-horsepower engines. 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.
