  • Hard anodized top ring groove eliminates micro welding of the ring to the groove; this maintains a flat and smooth surface for the best ring seal and top ring groove
  • Skirt coating eliminates piston rock for the best possible ring seal with no piston slap noise
  • Hard anodized crown to aid in heat deflection and to reduce corrosion from alcohol fuels
  • Includes pistons, rings, pins and clips
