Wiseco Chevy LS 4.035in 1.165in CH -17.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for Chevy LS engines that will see heavy use and demanding race conditions. These aren't your average pistons; they're built from the ground up to handle serious power and stress, making them a solid choice for builders who want to push their engine's limits.

Each piston is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for durability under high loads. You'll find precision ring grooves, an anti-detonation groove, 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 and forced pin oiling are further details that show these pistons are made for severe duty performance applications.

This set includes eight pistons, each with a 4.035-inch bore and a 1.165-inch compression height. The pin diameter is 0.927 inches. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine for racing or severe duty, this set offers a well-built foundation.
