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 the perfect 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 ideal for stock or mild compression ratios up to 10.5:1, perfect for those looking to enhance their engine’s performance without compromising on reliability. Additionally, these pistons are designed to run on pump fuel, making them a versatile choice for a wide range of applications.

Whether you’re cruising down the highway on your Harley Davidson FLHR Road King or tearing up the track on your FXDWG Dyna Wide Glide, these cast pistons will deliver the power and durability you need to take your ride to the next level.

So, if you’re looking to upgrade your engine with top-of-the-line pistons that offer unmatched performance and reliability, look no further than the KB Hypereutectic alloy pistons. Trust in their quality craftsmanship and innovative design to elevate your riding experience to new heights.
