Why Conical Springs Outperform Traditional Designs
Conical springs use variable coil diameter and spacing to naturally dampen valvetrain harmonics—reducing shock, minimizing wear, and extending component life. Compared to cylindrical or beehive springs, conical designs offer superior harmonic stability, making them ideal for engines pushed to the edge by aftermarket tuning.
Built for Reliability and Longevity
Each spring undergoes a multi-step heat treatment and receives a super-finished surface for enhanced durability and consistent performance. Whether you're chasing higher RPMs, more aggressive cam profiles, or elevated boost pressures, this kit is engineered to keep your VR30 valvetrain dialed in.
