Description

The Trick Flow by PAC Racing TFS-16519-16 are beehive-style valve springs engineered to improve engine performance and reliability. Manufactured in the USA by PAC Racing for Trick Flow Specialties, these springs provide a significant upgrade over stock components. Each spring in this set features a 209 lbs./in. spring rate, delivering 90 lbs. of seat pressure at 1.600 inches installed height and 205 lbs. of open pressure at 1.020 inches. This configuration supports up to .600 inches of valve lift, making them suitable for performance camshafts. The springs have a coil bind height of 0.980 inches and an outside diameter of 0.940 in./1.050 in., designed to fit within stock valve seats and work with stock retainers. These valve springs are specifically designed for use with Ford 4.6L/5.4L 2V engines, particularly those that are naturally aspirated. They are intended as an upgrade for performance applications, providing the necessary support for increased engine speeds and camshaft profiles.
