Wiseco Chevy LS 4.070in Bore 1.165in CH 10.00 CC Piston Set

When you're building a serious performance LS engine, you need parts that can handle the stress. This set includes eight forged pistons from Wiseco, designed for heavy to severe duty race applications. Each piston is forged and machined in the USA from 2618 aluminum, giving it improved tensile strength for demanding builds.

These aren't just basic pistons; they're packed with features for racers. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The fully machined crown ensures accuracy, and the forced pin oiling helps keep the wrist pins lubricated under extreme conditions. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set is intended for builders who are pushing their LS engines to the limit. They are designed to withstand the rigors of racing and severe duty use, offering a solid foundation for a high-performance engine build. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
