Wiseco Chevy LS 4.030in Bore 1.165in CH 10.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.030-inch bore size is a common specification for many Chevrolet LS engine applications, and the 1.165-inch compression height is crucial for achieving the desired 10.00 CC combustion chamber volume when paired with the right cylinder heads.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure robust performance under severe conditions. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly, all contributing to improved durability and efficiency in high-stress applications.

This set includes eight pistons, designed to withstand the rigors of severe duty race builds. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. It's always recommended to consult your engine builder or refer to Wiseco's installation instructions for specific details regarding assembly and compatibility with other engine components.
