Wiseco Chevy LS 4.065in Bore 1.165in CH 0.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Chevy LS engines that demand serious durability. If you're putting together a heavy-duty race engine or a severe-duty build, these pistons are designed to handle the stress and deliver consistent performance when you need it most.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to resist deformation under extreme pressure. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for both power and engine longevity. They also come with 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 system ensures the wrist pins stay well-lubricated.

This set includes eight pistons, each designed for a 4.065-inch bore with a 1.165-inch compression height and a 0.927-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for the highest levels of performance and reliability in their LS engine, these Wiseco pistons are a solid choice.
