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. They are suited for Street or Race applications with power adders such as NOS or boost. All Twin Cam and Sportster application feature coated skirts.
