Wiseco Chevy LSX 4.005in Bore 1.110in CH 11.80 CC Piston Set

If you're building a high-performance Chevrolet LSX engine, this set of Wiseco pistons is designed to handle some serious punishment. These are their Professional Series forged pistons, meaning they're built with no compromises for racers and builders who push their engines hard. They're made from 2618 aluminum, which is a strong material chosen for its high tensile strength, making these pistons well-suited for the demands of heavy to severe duty racing applications.

Wiseco machines these pistons right here in the USA, and they've included a lot of features to ensure durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep things quieter. The fully machined crown is ready for whatever you throw at it, and the forced pin oiling system helps keep the wrist pins lubricated under extreme conditions.

This set includes eight pistons, each with a 4.005-inch bore, a 1.110-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. For serious LSX builds, these Wiseco pistons are a solid choice.
