Supertech conical valve springs are meticulously crafted from premium materials to reduce valvetrain mass and improve efficiency. Their unique conical shape optimizes spring dynamics, providing superior stability at high RPM and under extreme conditions.
Because each coil has a different diameter, a conical spring has a constantly changing natural frequency, which greatly reduces harmonic resonance. The smaller top coil also allows a lighter retainer, further reducing moving mass.
Ideal for racing and high-performance applications where maximum RPM stability and minimum valvetrain mass are essential.
