Performance Springs Holden Alloytec & GM SIDI V6 PACALOY Beehive Valve Spring & Titanium Retainer Kit

This PVS Single PACALOY™ Ovate Beehive Valve Spring and Titanium Retainer Kit is designed for Holden Alloytec and GM SIDI V6 engines, including 3.0L, 3.2L, and 3.6L variants. It provides improved valvetrain stability, reduced mass, and reliable valve control for performance-focused street and track builds.

Manufactured in the USA, these PACALOY™ beehive valve springs utilise an ovate single-spring design to minimise harmonic resonance while maintaining consistent pressure throughout the valve lift range. Compared to conventional spring configurations, the beehive design reduces valvetrain inertia, improving RPM stability and valve control under increased load.

The kit includes lightweight titanium retainers, further reducing reciprocating mass and supporting accurate valve motion when paired with performance camshafts. Installed pressures are optimised for engines requiring improved control without excessive spring load, making this kit suitable for naturally aspirated and mild forced-induction applications.

This package is ideal for Alloytec and SIDI V6 engines where reliability, precision, and improved valvetrain performance are required.
