Wiseco Chevy LSX 4.155in Bore 1.110in CH 11.70 CC Piston Set

If you're building a serious performance engine for your Chevy LSX, these forged pistons from Wiseco are a solid choice. They're designed to handle the demands of heavy to severe duty racing applications, meaning they're built tough for when you're pushing your engine to its limits. Wiseco makes these in the USA from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum, making them well-suited for high-stress environments.

You'll find precision machining throughout, including the ring grooves, which have features for better ring seal. They also come with an anti-detonation groove to help prevent damage under high cylinder pressures. The piston crown is fully machined, and they feature forced pin oiling to keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a nice touch for a performance part like this.

This set includes eight pistons, and they're designed for a 4.155-inch bore with a 1.110-inch compression height and a 0.927-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For a high-performance build, these Wiseco pistons are a well-built option.
