The PSI Beehive Valve Spring Set 1516ML is engineered for high-performance racing applications, offering superior durability and performance enhancements tailored specifically for Circle Track and Road Circuit teams. This series builds upon the benefits of the renowned 1200 series by incorporating an advanced in-house nitriding process. This process increases the surface strength of the wire, enhancing fatigue resistance and longevity, even under the extreme stresses of competitive racing. While the nitriding process introduces a slight softening of the core material, it significantly boosts endurance, making it ideal for applications that demand extended durability without compromising performance.
- Advanced Nitriding Process: Increases surface strength while optimizing the material for enhanced endurance and fatigue resistance.
- Designed for Circle Track and Road Circuit Racing: Ideal for teams focused on endurance and long-term reliability, where resistance to fatigue is critical.
- .660″ Lift Capability: Engineered for high lift applications, allowing for improved airflow and overall engine performance.
- Beehive Design: Reduces mass, improves stability, and minimizes valve float for more consistent performance across a range of RPMs.
- Enhanced Material Properties: The nitriding process balances increased surface hardness with a slightly softened core, optimizing strength without compromising flexibility.
- Not Recommended for Drag Racing: The trade-off in core hardness is less suitable for drag racing, where peak strength is prioritized over endurance.
