We also utilize computer software that allows us to ensure that the harmonics are under control. All Supertech valve springs are made with premium super clean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high rpms. Using high quality steel alloy also provides the added benefit of better structural memory for all of our springs, giving your performance racing engine a serious competitive advantage.
