Wiseco Honda K-Series +10.5cc Dome 1.181x86.0mm Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series piston kit is a prime example, designed for serious builders working on Honda K-series engines. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding builds.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for keeping combustion pressure where it belongs. The crown is fully machined, and the piston pin features forced oiling to ensure it stays well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and keep things quieter. These pistons are built to handle heavy to severe duty performance applications, making them a solid choice for racing or high-performance street builds.

This kit includes four pistons, each with a +10.5cc dome and a bore size of 86.00mm. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
