High performance racing components, valves, pistons, springs, valve train engine components manufacturer and supplier. Production of SuperTech racing valves begin with a one piece forging, where the head of the valve is forged under a slow two-step process to keep a good material grain flow. The forging is then CNC machined in several steps to ensure the precision of the final dimensions. SuperTech then do another heat treatment for stress relieving followed by a nitride hardening treatment (or coating process depending on the application). Lastly, they do one more grinding, followed by our patented Superfinishing of the surface to ensure that each valve is free of any imperfections and the dimensions are precise.
