The valve springs from Supertech are made exclusively from extremely high-quality materials and thanks to the latest technology with the highest precision. In the case of the springs, it is a particularly pure chrome-silicon-vanadium-steel alloy. Thanks to this material, these sport springs are perfect for high-performance engines and high speeds. Furthermore, minimal wear can be guaranteed even under heavy loads.

Furthermore, all products are tested in a number of programs and wear fatigue is simulated in order to prevent them and to counteract them with the help of the latest materials and construction methods.
