Product Description

Hypereutectic Cast Piston

  • SKU: 824-01003
  • Manufacturer part number: KB258.020
  • UPC: 800745060389

Vehicle compatibility is shown in the fitment information below.

KB 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.
