The KB Hypereutectic alloy pistons are a true marvel in the world of engine components. Crafted with a 16% high silicon content, these pistons boast exceptional thermal barrier properties and a low thermal expansion rate. This unique combination allows for tight piston to cylinder wall clearances, making them an ideal choice for air-cooled engines.

One of the standout features of these pistons is their ability to provide optimal ring seal, resulting in quieter engine running and reduced wear over time. This is crucial for maintaining the longevity and performance of your engine, especially in high-stress situations.

The Hypereutectic alloy construction also makes these pistons well-suited for stock or mild compression ratios up to 10.5:1, making them compatible with pump fuel. This versatility ensures that these pistons can cater to a wide range of engine setups, providing reliability and performance in various applications.

Whether you’re cruising down the highway on your Harley Davidson FLHT Electra Glide or tearing up the trails on your FXDWG Dyna Wide Glide, these cast pistons will deliver the power and durability you need to conquer any terrain. Upgrade your engine with the KB Hypereutectic alloy pistons and experience the difference in performance and reliability.

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.
