Overview
These pistons are OE quality and have the same great OE features such as compensated ring grooves to assure proper ring loading and oil control, as well as expansion controlled designs for small fitting clearances to reduce engine noise, wear, emissions, and improve oil control. We use one of the largest OE piston manufacturers in the world - leaving nothing to chance.
Features & Benefits:
- Hypereutectic piston cast with FM S2N proprietary alloy
- DUROSHIELD® skirt-coated piston helps prevent scuffing of skirt and cylinder wall
- to improve piston-to-ring side sealing, providing exceptional blow-by control, improved efficiency and better economy
- Moly-graphite coating extends engine life
- Up-tilt ring grooves to improve piston-to-ring side sealing, providing exceptional blow-by control, improved efficiency and better economy
- Prevents damage from inadequate lubrication on start-up
- Elastoval design decreases crown temperature, reducing the risk of engine knocking in hotter, higher pressure engines, while maintaining high structural strength
