MACE Performance Valve Springs — Built for Stable Lift & Confident Valve Control

Valve springs are essential for maintaining accurate valve motion when lift, duration and airflow demands rise. Experience exceptional reliability with our high-performance valve springs formed from premium Japanese spring wire—chosen for purity, tensile strength, and superior fatigue resistance. Engineered for high-RPM and heavy-load conditions, they deliver stable valve control and reduced float even under aggressive cam or boosted setups. Precision-wound, heat-treated, and shot-peened, they maintain consistent performance under extreme stress. Built for serious enthusiasts who demand strength, control, and durability.

These valve springs suit Holden vehicles fitted with Ecotec L36 and L67 Supercharged V6 engines.
