Wiseco Chevy LS 4.075in Bore 1.165in CH 10.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy LS engines. The 4.075-inch bore size and 1.165-inch compression height are key dimensions for many LS engine builds, especially those aiming for increased displacement and power. Wiseco machines these pistons in the USA, ensuring precise tolerances for critical components like the ring grooves and pin bores.

You'll find features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements designed to handle the stress of heavy to severe duty racing applications. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins lubricated under extreme conditions. A notable feature is the ArmorGlide skirt coating, which Wiseco developed to reduce friction, resist seizure, and contribute to quieter operation, all important factors when pushing an engine to its limits.

This set includes eight pistons, along with premium rings, ready for a demanding build. Keep in mind these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
