Performance Springs Ford Barra XR6 BA/BF/FG/FGX PACALOY Beehive Valve Springs

PACALOY™ ovate beehive valve springs for Ford Barra BA/BF/FG/FGX engines. Direct drop-in replacement using factory retainers and locks.

These PVS Single PACALOY™ Ovate Beehive Valve Springs are designed as a direct drop-in upgrade for Ford Barra BA and BF engines, offering improved valve control while retaining the factory valve spring retainers and locks.

Manufactured in the USA, these springs feature PACALOY™ ovate wire technology, which improves fatigue resistance and long-term durability under repeated high-load cycles. The beehive profile reduces mass at the retainer end of the spring, improving valvetrain stability and helping control valve motion at higher engine speeds.

Designed for straightforward installation, these valve springs install at a 95 lb seat pressure and deliver 235 lbs of open pressure at 0.500” lift, making them suitable for performance camshaft applications where improved control is required without moving to heavier dual-spring setups.

This spring-only package is ideal for Barra owners looking for a reliable, cost-effective valvetrain upgrade while continuing to use OEM retainers and locks.
