Wiseco Chevy LS 4.030in Bore 1.165in CH 5.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which gives them improved tensile strength for the demands of heavy to severe duty applications. They're designed to handle the stress and heat that come with pushing an engine hard, making them a reliable foundation for your build.

Wiseco has packed a lot of smart features into these pistons. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for both power and longevity. The fully machined crown ensures accuracy, and they also feature forced pin oiling to keep the wrist pins well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, which is a big plus when you're running an engine at its limits.

This set includes eight pistons, each with a 4.030-inch bore, a 1.165-inch compression height, and a 0.927-inch pin diameter. Keep in mind these are intended for racing and performance builds, and they are not CARB approved, so they cannot be shipped to California. For a robust bottom end that can take a beating, these Wiseco pistons are a well-built option.
