Upgrade your Twin Cam engine with the high-performance KPMI Cylinder Studs, designed to deliver maximum strength and durability. Crafted from premium 8740 alloy steel with a yield strength of 180,000 psi, these studs are engineered to withstand the most demanding conditions in your engine. Their fine grain, heat-treated construction ensures superior toughness, while the rolled threads after heat treatment maximize compressive stresses and extend fatigue life, providing long-lasting reliability. The case end threads feature a slight interference fit to maintain optimal thread contact at elevated temperatures, preventing loosening during operation. Each stud is centerless ground to guarantee perfect concentricity, resulting in precise fitment and consistent performance. Finished with a premium black oxide coating, these studs not only perform excellently but also offer an attractive appearance that resists corrosion and wear, maintaining their integrity over time.
