Wiseco Chevy LS Series +9cc Dome 1.311x4.020in Pistons Shelf Stock

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy LS engines. The +9cc dome volume is a specific design choice that impacts compression ratio, and the 4.020-inch bore size is crucial for matching your engine's needs. Wiseco's Professional Series is engineered for builders who demand durability and performance in heavy to severe duty race applications.

These pistons feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to ensure the wrist pins stay lubricated under high stress. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. This attention to detail means these pistons are made to handle the rigors of demanding builds.

This set includes eight pistons, designed to fit your Chevy LS engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
