Shot peening is applied to high-quality valve spring silicon chromium steel oil tempered wire (JISSWOSC-V) to improve metal fatigue strength.
This prevents heat sagging even during long-term use at high temperatures, ensuring stable performance. Made in Japan for peace of mind.
Please select the product with the optimal spring rate after fully understanding your vehicle's engine horsepower and peak power generation RPM.
