Wiseco Chevy LS 4.065in Bore 1.165in CH 10.00 CC Piston Set

This is a set of Wiseco Professional Series forged pistons designed for Chevrolet LS engines with a 4.065-inch bore. These pistons are built for serious racers and builders who need robust components for 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, ensuring efficient combustion and durability. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins lubricated under high stress. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. These are designed to be a no-expense-spared component for high-performance engine builds.

This set includes eight pistons, along with premium rings. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing use where emissions regulations may differ.
