Wiseco Chevy LS 4.125in Bore 1.165in CH 6.00 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 serious racers and builders who push their Chevy LS engines hard. These aren't your average pistons; they're packed with features designed for heavy to severe duty race builds, giving you the confidence to remove your limits.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions. You'll find precision ring grooves, anti-detonation grooves, and other features that help 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 ensures accuracy, and forced pin oiling helps keep the wrist pin lubricated under extreme stress.

This set includes eight pistons, each designed for a 4.125-inch bore with a 1.165-inch compression height and a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a severe duty LS engine, this set is designed to handle the stress.
