All Supertech valve springs are made from premium Superclean Chrome Silicon Vanadium Steel alloy for increased high-rpm performance and durability. The use of a high quality steel alloy also offers the added benefit of a better structure for all our springs. Our valve springs are computer designed to ensure wire tension levels do not exceed the limits of tension defined in the fatigue charts. We also use computer software that allows us to ensure that these are harmonically under control. This combined with our high quality steel alloy allows supertech valve springs to be more durable under extreme conditions, giving your performance bike a serious competitive edge in performance and durability. Supertech holders/retainers are manufactured with high quality military certified titanium alloy and are CNC machined for a tight fit. Our high-quality holders are among the best in the industry.
