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 beehive valve springs allow you to drop in a more aggressive cam without machining your spring seats (most applications). 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.
