Wiseco Chevy LS 4.085in 1.165in CH -20.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially pistons, for high-performance applications. This Professional Series piston set is built for Chevy LS engines and is designed for serious racers and builders who need parts that can handle heavy to severe duty. They are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

These pistons come with precision ring grooves, an anti-detonation groove, and other features to improve ring seal. They also have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and the forced pin oiling helps keep things lubricated. If you're putting together a serious race engine or a severe duty performance build, these pistons are made to withstand the stress.

This set includes eight pistons, each with a 4.085-inch bore and a 1.165-inch compression height, using a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
