2.3 Ecoboost Beehive Spring Kit

Race-Ready Valve Control. The Kelford Cams PACALOY Beehive Valve Spring Kit is engineered for serious performance in high-RPM EcoBoost builds. Designed to enhance valve control and resist valve float, these beehive springs support both stock and aggressive aftermarket camshaft profiles for improved top-end power and engine stability. Made from high-strength Pacaloy alloy, the springs offer increased fatigue resistance and longevity under extreme conditions. Their beehive shape reduces mass at the valve tip, improving efficiency and performance at elevated RPMs. Installation is difficult and should be performed by experienced technicians. Cylinder head removal and specialized spring compression tools are required for proper fitment and setup.
