Wiseco Chevrolet LS 4.070in Bore 1.304in CH -3.20 CC Professional Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. If you're building a serious LS engine for your 1997-2004 Chevrolet Corvette, or another compatible GM vehicle, this Professional Series piston set is built to handle extreme conditions. These aren't your average pistons; they're designed from the ground up for heavy to severe duty racing and performance builds where reliability under stress is critical.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential when dealing with the high pressures and temperatures of a performance engine. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. The piston crown is fully machined, and they feature forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even under demanding use.

This set includes eight pistons, each with a 4.070-inch bore, a 1.304-inch compression height, and a 0.927-inch pin diameter. They are designed to fit LS engines and are a solid option for builders looking for pistons that can withstand the rigors of competition or high-performance street driving. Please note that these pistons are not CARB approved and cannot be shipped to California.
