Valve Springs

Trick Flow® by PAC Racing Beehive Valve Springs

Trick Flow by PAC Racing Beehive Valve Springs are manufactured to Trick Flow’s rigorous, world-class standards. Every spring is CNC coiled from high tensile-strength, extra-durable Pacaloy™ chrome-silicon steel and double shot-peened beyond Aerospace Material Specifications (AMS) reliability criteria. These beehive springs allow you to drop in a more aggressive cam without machining your spring seats. The springs feature heavyweight spring rates but still fit inside the stock valve seats and can be used with the stock retainers.
