Why Conical Springs Outperform
Conical valve springs are proven to outperform cylindrical and beehive designs by naturally damping valvetrain harmonics. Their tapered coil diameter and spacing act as built-in shock absorbers, reducing stress and wear—especially vital in engines pushed to the edge by aggressive aftermarket setups.
