This PVS Single PACALOY™ Ovate Beehive Valve Spring and Titanium Retainer Kit is engineered for Ford XR8 5.4L 4-valve Modular V8 engines, delivering improved valvetrain stability, reduced mass, and reliable control in performance street and track applications.
Manufactured in the USA, these PACALOY™ valve springs utilise an ovate beehive design to reduce harmonic resonance while maintaining consistent spring pressure across the operating range. The single spring configuration lowers overall valvetrain weight compared to traditional dual spring setups, helping improve engine response and high-RPM stability.
The kit is supplied with lightweight titanium retainers, further reducing reciprocating mass and improving valve control under aggressive cam profiles. Installed pressures are optimised for performance camshaft applications while maintaining compatibility with properly set up factory and aftermarket valvetrain components.
This package is ideal for naturally aspirated or mild forced-induction builds where reliability, precision, and reduced valvetrain inertia are critical.
