Wiseco AC/HON B 4v DOME +8.25 STRUT 8500XX Piston Shelf Stock *SINGLE PISTON ONLY*

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series forged piston is built with that same focus, designed for serious racers and builders who push their engines hard. It's made from 2618 aluminum, which is forged and machined in the USA for improved tensile strength, making it a solid choice for heavy to severe duty race builds.

This piston features precision ring grooves, an anti-detonation groove, and other features to improve ring seal. It also comes with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. The crown is fully machined, and it includes forced pin oiling to keep things well-lubricated under demanding conditions. This is a single piston, intended for use in Honda B16A engines with an 85.00 mm bore.
