The KPMI Cylinder Stud Kit (Part Number 80-82650) is designed for high-performance Yamaha engine applications, offering exceptional strength and durability. Crafted from premium-grade 8740 material with a yield strength of 180,000 psi, these studs are engineered to withstand demanding conditions. The heat-treated, fine grain construction ensures optimal toughness, while the rolled threads after heat treatment maximize compressive stresses, providing superior strength and fatigue life. Ideal for racing or high-stress environments, these studs maintain their integrity under extreme heat and pressure. The case end threads are engineered with a slight interference fit to ensure reliable thread contact at elevated temperatures, reducing the risk of loosening during operation. Each stud is centerless ground to guarantee perfect concentricity, which contributes to consistent performance and precise engine assembly. The black oxide finish enhances corrosion resistance and offers an attractive appearance, making these studs both functional and visually appealing. Suitable for professionals and enthusiasts seeking reliable, high-performance engine components, the KPMI Cylinder Stud Kit ensures your Yamaha engine remains secure and performs at its best under intense conditions.
