Why Conical Springs?
Conical springs outperform traditional cylindrical and beehive designs by naturally dampening valvetrain harmonics. Their tapered coil geometry helps absorb shock and reduce stress, extending component life and improving stability at high RPM.
Built for Extreme Conditions
Each spring undergoes a multi-stage heat treatment and super-finishing process to maximize durability and performance. Whether you're chasing higher RPMs or running aggressive cam profiles, this kit is built to keep up with the demands of modern turbocharged engines.
