KB Performance KB266.030 Cast Piston Kit (80ci., Domed) - .030in. Oversize to 3.528in., 10.5:1 Compression

Kb Pistons KB266.030 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.

High-quality premium performance pistons are a special hypereutectic T5 aluminum alloy This alloy makes it possible to build a lightweight piston that makes more power, runs great, uses less fuel and lasts longer than other pistons Kit includes 2 cast pistons, 1 set of Hastings moly rings and piston pin clips Instructions included Use lock rings MFG #RRN-81 pkg. of 4
