Silv-O-Lite’s hypereutectic pistons use an alloy containing 15 - 16% silicon. In addition to greater strength, scuff and seizure resistance, the hypereutectic will improve groove wear and resist cracking in the crown area where operating temperatures are severe.
IMPORTANT: Hypereutectic aluminum has 15% less thermal expansion than conventional piston alloys. When using Hypereutectic pistons Silv-o-Lite recommends 40% increase in listed top ring end gap.
