Wiseco Chevy LS 4.155in Bore 1.165in CH -2.00 CC Piston Set

When you're building a serious performance engine, especially for racing, you need parts that can handle the stress. This set from Wiseco gives you eight Professional Series forged pistons, designed to take on heavy and severe duty applications. They're made in the USA from 2618 aluminum, which is chosen for its improved tensile strength, meaning it can handle higher pressures and temperatures without deforming.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features to ensure a solid seal and prevent detonation. They also come with an ArmorGlide skirt coating. This coating helps reduce friction for smoother operation, resists seizure if things get hot, and contributes to quieter running. The fully machined crown is ready for your build, and the forced pin oiling design helps keep the wrist pins properly lubricated under extreme conditions.

This set includes eight pistons, each with a 4.155-inch bore, a 1.165-inch compression height, and a 0.927-inch pin diameter. Keep in mind these are intended for racing and severe duty builds, and they are not CARB approved, so they cannot be shipped to California.
