CAST PISTONS TWIN CAM 88CI 8.8:1 .020 2008 Harley-Davidson FXCW Softail Rocker 21mm: main jet 95KB Hypereutectic alloy pistons are cast with a 16% high silicon content that has very high thermal barrier properties along with a low thermal expansion rate, allowing tight piston to cylinder wall clearances. This makes them ideal for air cooled engines, offering optimal ring seal, quieter engine running and reduced wear. Hypereutectics are best suited for stock or mild compression ratios up to 10. 5: 1 running on pump fuel.
