1200 Series
Every PSI spring begins with wire that is made from the highest quality Chrome-Silicon alloys. The 1200 Series builds on this 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.

Max Life Surface Preparation (ML)
A proprietary, multi-step surface enhancement process that has been proven to increase spring endurance, Max Life processing is available for any level of PSI spring and is very beneficial for those looking for increased endurance while maintaining their existing set-up.
