Wiseco Chevy LS 3.800in Bore 1.165in CH 10.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength to handle the demands of severe duty race applications. The 3.800-inch bore size is specific to certain Chevrolet LS engine configurations, and the 1.165-inch compression height is a critical measurement for setting up your engine's valve timing and piston-to-valve clearance. Each piston in this set of eight features precision machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring efficient combustion and durability under high stress.

Wiseco's Professional Series pistons are designed for builders who need robust components for heavy-duty performance. The fully machined crown ensures consistent combustion chamber volume, while the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life. Forced pin oiling is incorporated to ensure the wrist pin receives adequate lubrication, a crucial detail for high-performance engines that see constant, heavy use. These pistons are engineered and machined in the USA, reflecting a commitment to quality and performance for serious racers and builders.

When rebuilding or modifying your LS engine for demanding performance, these Wiseco pistons offer a well-built foundation. Keep in mind that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
