Wiseco Chevy LS 4.155in 1.165in CH -23.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for Chevy LS engines and is designed for serious racers and builders who need parts that can handle heavy to severe duty use. These aren't your average pistons; they're packed with features aimed at improving both performance and durability under extreme conditions.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated, which is crucial for longevity in high-stress engines.

This set includes eight pistons, each with a 4.155-inch bore and a 1.165-inch compression height, using a 0.927-inch pin diameter. Keep in mind these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine that needs to withstand serious abuse, these pistons are a solid choice.
