Through PSI’s program of continuous product improvement, the 1200 Series builds on the success of the 1000 Series by employing advanced heat-treating operations. These heat treatments increase the strength of the base materials. This increase in strength results in improvement to the fatigue limit of the wire and better resistance to load loss. These factors together allow the engine builder to push the valve train set-up to the next level.
