Wiseco Chevy SMALL BLK 1.420 4165A Piston Shelf Stock

Forged from 2618 aluminum, this Wiseco piston is built for demanding Chevy Small Block applications. The material choice here offers improved tensile strength, which is crucial for handling the higher stresses found in performance and racing engines. This piston is designed to be a robust component for builders looking for durability under heavy use.

Beyond the strong aluminum forging, this piston features Wiseco's ArmorGlide skirt coating. This coating helps reduce friction during operation, leading to quieter running and improved seizure resistance, which is a notable benefit in high-performance scenarios. The crown of the piston is also fully machined, with precision ring grooves and an anti-detonation groove, along with features that enhance ring seal. Plus, it includes forced pin oiling to ensure the piston pin stays well-lubricated, further contributing to its ability to withstand severe duty.

This is a shelf stock piston, meaning it's a popular, readily available option for many Chevy Small Block builds. Keep in mind that this part is not CARB approved and cannot be shipped to California.
