About this part

Product Details

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston kit is a prime example, designed for Chevy LS engines that demand serious durability. These aren't your average pistons; they're built from the ground up for heavy to severe duty racing builds where every component needs to perform under extreme stress.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for handling high combustion pressures. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. 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 further contribute to their robust design, making them ready for the toughest conditions.

This kit is intended for builders who are pushing their LS engines to the limit. While these pistons are built for performance, please note they are not CARB approved and cannot be shipped to California. Ensure you check all manufacturer specifications and local regulations before installation.
