Wiseco Chevy LS 4.165in Bore 1.165in CH -23.00 CC Piston Set

When you're building a serious performance LS engine, you need components that can handle the stress. This set gives you eight Wiseco Professional Series forged pistons, ready to be installed in your Chevrolet LS engine. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-performance applications.

These aren't just basic pistons; they're packed with features for racers and builders who push their engines hard. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and the forced pin oiling helps keep the wrist pin lubricated under extreme conditions. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, all while being designed to withstand heavy to severe duty performance builds.

This set includes eight pistons, each with a 4.165-inch bore, a 1.165-inch compression height, and a -23.00cc dish volume. The wrist pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
