The PAC Racing PAC-1214 valve springs provide a high-performance valvetrain upgrade for Ford 4.6L 2V modular engines. As part of the 1200-series, these ovate beehive springs are designed to offer improved stability and reliability over stock components. They serve as a direct-fit, drop-in replacement, allowing for installation using stock retainers and seats without requiring additional head machining. Technical specifications include a seat pressure of 100 lbs at an installed height of 1.640 inches, with an open pressure of 265 lbs at 1.080 inches. With a spring rate of 275 lb/in and a coil bind height of 1.040 inches, they accommodate a maximum valve lift of 0.600 inches. Installation should be performed by verifying all specifications with the manufacturer or a professional engine builder before final assembly to ensure correct fitment within your specific engine configuration.
