Wiseco Chevy Small Block 4.060in Bore 1.250in CH -1.70 CC Piston Set

This Wiseco Professional Series piston set includes eight forged pistons, designed for Chevrolet small block engines with a 4.060-inch bore. These pistons are 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 conditions.

Each piston features precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the pins lubricated. Wiseco also includes an ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and contribute to quieter operation. These are no-expense-spared pistons aimed at pushing performance limits.

This set is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. For builders looking for robust components for a high-performance engine, these pistons offer a well-built option with features geared towards durability and consistent performance under stress.
