Wiseco Chevy LS 4.000in Bore 1.165in CH 10.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle the toughest conditions. Designed and machined in the USA from 2618 aluminum, these pistons offer improved tensile strength, making them a solid choice for heavy to severe duty race builds where reliability is key.

Each piston features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and performance under extreme stress. This set is designed to remove limits for those pushing their engines hard.

This set includes eight pistons, each with a 4.000-inch bore, a 1.165-inch compression height, and a 0.927-inch pin diameter. Please note 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.
