Piston kits & Components

KB forged pistons are made from 4032 forged alloy with an 11% silicon content, formed in a forging press and then fully machined. Due to the material and manufacturing process these pistons have superior crack resistance under detonation or pre-ignition...

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...
