Wiseco Chevy LT1 4.065in Bore 1.105in CH -6.90 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle severe duty. They are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to handle the stresses of demanding engine builds.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. Plus, these pistons come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizure, all crucial for keeping your engine running smoothly under extreme conditions. The fully machined crown also contributes to their robust design, ensuring they are ready for heavy use.

This set includes eight pistons, each with a 4.065-inch bore and a 1.105-inch compression height. They also feature forced pin oiling to ensure the wrist pins stay well-lubricated. Keep in mind these are not CARB approved and cannot be shipped to California.
