For 100 years Silv-o-lite has produced high quality OE replacement pistons for engine rebuilding. Every manufacturing process is done in house, including alloying the aluminum, casting, heat treating, diamond machining, and a full array of anodizing and coatings for the piston crowns, ring grooves, and skirts.

Anodizing Features:
  • Limits micro welding of ring to groove in severe conditions
  • Produces a very hard surface for ring to rotate on
  • Creates barrier from corrosive fuels
