Engineered for high-output Honda K-Series race builds, these Wiseco Professional Series forged pistons are designed for builders who demand maximum thermal stability and tensile strength. Machined in the USA from premium 2618 aluminum alloy, this shelf stock kit is purpose-built to withstand the extreme cylinder pressures of heavy to severe-duty performance applications.

Each piston features Wiseco’s proprietary ArmorGlide skirt coating, which reduces friction and provides superior seizure resistance for quieter, more reliable operation. The fully machined crowns incorporate anti-detonation grooves to protect the ring land while forced pin oiling ensures the wrist pins remain lubricated under high-load conditions.
