Wiseco Chevy LS 4.080in 1.165in CH -20.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is built with that reputation in mind, designed for Chevy LS engines that will see heavy or severe duty use. If you're building a serious race engine or a street/strip machine that needs to handle a lot of power, these pistons are a solid choice.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they also come with forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. For added durability and reduced friction, the skirts are coated with ArmorGlide, which helps resist seizure and makes operation quieter.

This set includes eight pistons, each with a 4.080-inch bore, a 1.165-inch compression height, and a -20.00cc dish volume. The pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for demanding performance builds where reliability and strength are paramount.
