KB piston designers have pushed the PM process to new levels with KB's unique rib design for skirt strength, in addition to metal removal under the pin boss for weight reduction. This distictive KB design affords you, the racer, unparalleled piston durability and longer piston life. Every feature of the KB piston is carefully engineered to provide the most consistent, high-tech piston on the market. We pay close attention to the little things because we know they can mean big results. KB's hypereutectic alloy produces lower rates of thermal conductivity.
Thermal conductivity is reduced by about two-thirds.
That translates to less heat transmitted down the piston skirt and into the oil, leaving more heat available to move the piston.
