Wiseco Chevy LS 3.780in 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 a prime example, designed for serious racers and builders who need parts that can handle extreme conditions. If you're putting together a heavy or severe duty race engine for your Chevy LS, these pistons are built to take the punishment.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown is ready for your build, and they come with forced pin oiling to keep things well-lubricated.

This set includes eight pistons, each with a 3.780-inch bore and a 1.165-inch compression height. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming to push their LS engine to the limit, these pistons offer a solid foundation.
