Wiseco Chevy Big Block 4.630in Bore 1.120in CH 15.60 CC Piston Set

This is a set of 8 forged pistons from Wiseco, designed for Chevrolet Big Block engines. These pistons feature a 4.630-inch bore and a 1.120-inch compression height, with a 15.60 CC dish volume. They are built from 2618 aluminum, which is forged and machined in the USA to give you improved tensile strength for demanding applications.

Wiseco has packed these Professional Series pistons with features for serious racers and builders. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crowns are fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, make operation quieter, and resist seizure.

These pistons are designed and built to handle heavy to severe duty performance builds. Keep in mind that this set is not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's installation instructions for details on fitting these pistons to your specific engine build.
