Wiseco Chevy LS 4.030in Bore 1.165in CH -9.00 CC Piston Set

When you're building a high-performance Chevrolet LS engine for serious racing or severe duty applications, the pistons are a critical component. This set of eight forged pistons from Wiseco is designed to handle the extreme demands of competition. They are made in the USA from 2618 aluminum, which offers improved tensile strength to withstand the high pressures and temperatures found in racing engines.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features that improve ring seal for better combustion efficiency. The piston crowns are fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins properly lubricated under load. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is notable in a high-performance build.

This set is intended for builders who are pushing their LS engines to the limit. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete build, be sure to check the manufacturer's recommendations for rings and other necessary components.
