Wiseco Honda 4v DOME +6.5cc STRUTTED 89MM Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle heavy to severe duty in race builds. These pistons are designed to remove your limits when you're pushing your engine hard.

Each piston is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding use. They feature precision ring grooves, an anti-detonation groove, and other features to help seal the rings better. The crown is fully machined, and they have forced pin oiling to keep things lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and makes operation quieter.

This is a set of four pistons, each with an 89.00 mm bore and a 31.00 mm compression height. The pin diameter is 0.866 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
