Supertech Performance SPR-V1107 High-Performance Valve Springs Chrome Silicon Vanadium Steel

The Supertech Performance SPR-V1107 Valve Springs are precision-engineered performance valve springs designed for high-RPM applications where reliability and durability are critical. Constructed from premium Superclean Chrome Silicon Vanadium Steel Alloy, these springs offer superior fatigue resistance and long service life compared to standard OEM valve springs.

Each spring is computer-designed to maintain wire stress levels within safe operating thresholds, preventing premature failure even under sustained high-performance use. The Chrome Silicon Vanadium alloy provides excellent spring memory retention, meaning the springs maintain consistent pressure and seat load over time — a critical factor in maximizing valve train performance and engine reliability.

Key Features:

• Manufactured from premium Superclean Chrome Silicon Vanadium Steel Alloy for enhanced strength and longevity
• Computer-designed geometry to keep wire stress within optimal limits
• Superior spring memory retention for consistent valve pressure at high RPM
• Engineered for extreme operating conditions including forced induction and high-lift camshaft applications
• Long-term durability under sustained performance use
• Sold individually (per valve spring) — order the exact quantity needed for your application

Supertech Performance valve springs are a popular upgrade for enthusiasts building high-performance street, track, and competition engines. These springs are sold per individual spring — if your engine requires 16 valve springs, order a quantity of 16.
