Wiseco Chevy Big Block 4.610in Bore 1.060in CH 48.70 CC Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chevrolet Big Block engines with a 4.610-inch bore. These are Wiseco's Professional Series pistons, built for serious racers and builders who need components that can handle heavy to severe duty performance applications. They are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds.

You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. The pistons also come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown ensures accuracy, and forced pin oiling is incorporated to keep the wrist pins lubricated under high stress.

These pistons are intended for racing applications and are not CARB approved, meaning they cannot be shipped to California. If you're rebuilding a high-performance Big Block for racing, these pistons are a solid option to consider for their robust construction and specialized features.
