Our High RPM Dual Valve Springs have been manufactured using only the world's best Japanese Kobe steel and designed with more seat pressure and increased lift capability to maximize their valve control performance. Our final stride to acheive the highest quality spring was adding the dual chamfered ends to minimize weater and tear on the retainers and seats.
