Wiseco Chevy LS 4.125in Bore 1.165in CH -12.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious Chevy LS engine builders who demand top-tier performance and durability. These aren't your average pistons; they're designed from the ground up to handle the stress of heavy to severe duty racing builds, giving you the confidence to push your engine's limits.

Each piston is forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is critical for consistent power and engine health. 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 pin lubricated under high loads.

This set includes eight pistons, each designed for a 4.125-inch bore with a 1.165-inch compression height and a -12.00cc dish volume. If you're building a high-performance LS engine for racing or severe duty, these pistons are a solid choice to form the foundation of your build. Please note that these pistons are not CARB approved and cannot be shipped to California.
